Description

Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:

  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition

Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.

Customer Impact

None. Infrastructure-only change affecting CI test execution environment.

Regression

No. This is a proactive update to use a newer OpenSUSE version for testing.

Testing

Configuration change only. Will be validated through CI pipeline execution on the updated platform.

Risk

Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.

Package authoring no longer needed in .NET 9

IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older versions.

Original prompt

On helix-queues-setup.yml, Please update Open SUSE testing from to 16.0. Most references will be 15.6 like this this file: https://github.com/dotnet/runtime/blob/main/eng/pipelines/libraries/helix-queues-setup.yml

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh

Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.

@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet

Fixes Issue 
main PR 
Description
Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:
  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition
Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.
Customer Impact
None. Infrastructure-only change affecting CI test execution environment.
Regression
No. This is a proactive update to use a newer OpenSUSE version for testing.
Testing
Configuration change only. Will be validated through CI pipeline execution on the updated platform.
Risk
Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.
Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.

Keep in mind that we still need package authoring in .NET 8 and older versions.

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.

Fixes Issue 
main PR 
Description
Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:
  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition
Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.
Customer Impact
None. Infrastructure-only change affecting CI test execution environment.
Regression
No. This is a proactive update to use a newer OpenSUSE version for testing.
Testing
Configuration change only. Will be validated through CI pipeline execution on the updated platform.
Risk
Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.
Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.

Keep in mind that we still need package authoring in .NET 8 and older versions.
Original prompt
On helix-queues-setup.yml, Please update Open SUSE testing from to 16.0. Most references will be 15.6 like this this file: https://github.com/dotnet/runtime/blob/main/eng/pipelines/libraries/helix-queues-setup.yml

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.

Fixes Issue 
main PR 
Description
Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:
  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition
Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.
Customer Impact
None. Infrastructure-only change affecting CI test execution environment.
Regression
No. This is a proactive update to use a newer OpenSUSE version for testing.
Testing
Configuration change only. Will be validated through CI pipeline execution on the updated platform.
Risk
Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.
Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.

Keep in mind that we still need package authoring in .NET 8 and older versions.
Original prompt
On helix-queues-setup.yml, Please update Open SUSE testing from to 16.0. Most references will be 15.6 like this this file: https://github.com/dotnet/runtime/blob/main/eng/pipelines/libraries/helix-queues-setup.yml

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.

Fixes Issue 
main PR 
Description
Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:
  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition
Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.
Customer Impact
None. Infrastructure-only change affecting CI test execution environment.
Regression
No. This is a proactive update to use a newer OpenSUSE version for testing.
Testing
Configuration change only. Will be validated through CI pipeline execution on the updated platform.
Risk
Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.
Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.

Keep in mind that we still need package authoring in .NET 8 and older versions.
Original prompt
On helix-queues-setup.yml, Please update Open SUSE testing from to 16.0. Most references will be 15.6 like this this file: https://github.com/dotnet/runtime/blob/main/eng/pipelines/libraries/helix-queues-setup.yml

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.

Fixes Issue 
main PR 
Description
Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:
  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition
Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.
Customer Impact
None. Infrastructure-only change affecting CI test execution environment.
Regression
No. This is a proactive update to use a newer OpenSUSE version for testing.
Testing
Configuration change only. Will be validated through CI pipeline execution on the updated platform.
Risk
Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.
Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.

Keep in mind that we still need package authoring in .NET 8 and older versions.
Original prompt
On helix-queues-setup.yml, Please update Open SUSE testing from to 16.0. Most references will be 15.6 like this this file: https://github.com/dotnet/runtime/blob/main/eng/pipelines/libraries/helix-queues-setup.yml

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.

Fixes Issue 
main PR 
Description
Updates OpenSUSE test platform version from 15.6 to 16.0 in Helix queue configurations:
  • eng/pipelines/helix-platforms.yml: Updated helix_linux_x64_opensuse_latest variable
  • eng/pipelines/libraries/helix-queues-setup.yml: Updated extra-platforms CoreCLR queue definition
Both files now reference opensuse-16.0-helix-amd64 container images and openSUSE.16.0.Amd64.Open queue names.
Customer Impact
None. Infrastructure-only change affecting CI test execution environment.
Regression
No. This is a proactive update to use a newer OpenSUSE version for testing.
Testing
Configuration change only. Will be validated through CI pipeline execution on the updated platform.
Risk
Low. Standard platform version update. Helix infrastructure team maintains the referenced container images, and the queue naming convention follows established patterns used for other platform updates.
Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet package's csproj to enable building and bump the version.

Keep in mind that we still need package authoring in .NET 8 and older versions.
Original prompt
On helix-queues-setup.yml, Please update Open SUSE testing from to 16.0. Most references will be 15.6 like this this file: https://github.com/dotnet/runtime/blob/main/eng/pipelines/libraries/helix-queues-setup.yml

Looks like I didn't properly test Ubuntu 26.04, at least not in all test runs, before merging. My mistake. @tarekgh
Looks like very famiiar glob/loc issues for a new generation of Linux distros. We hit similar sorts of issues with Ubuntu 24.04 and Debian 13 when we were adding coverage for within the last 18 months. These issues should be resolved as part of a new PR, but this is the first I'm seeing them so registering them here and since they are easy to see here.

@richlander I’m currently out and won’t be responsive, but I’ve created PR #122480 to address the failures you’re seeing. If needed, feel free to merge it before merging yours.
@jeffhandley The change I made here is effectively a breaking change, and I’ve addressed the issue in .NET 11. I expect that anyone using .NET 10 on Ubuntu 26.04, or any distro with ICU v87, may run into a similar issue with the Japanese calendar. The breaking change affects the minimum supported date for the Japanese calendar, so the impact should be minimal, but we should keep an eye out for any scenarios where users might encounter problems. If necessary, we can consider porting the fix to .NET 10.

[release/10.0] Update OpenSUSE container references to 16.0 and add t…
e08f350
…est compatibility fixes (#122373)
main PR #122371
# Description
Updates OpenSUSE container version from 15.6 to 16.0 in Helix pipeline
configuration for Linux x64 CoreCLR extra-platforms testing, and
includes necessary test fixes to ensure compatibility with OpenSUSE
16.0.
**Infrastructure Changes:**
- **`eng/pipelines/libraries/helix-queues-setup.yml`**: Updated queue
name and container image from `openSUSE.15.6` to `openSUSE.16.0`
**Test Compatibility Fixes (backported from main PR #122371):**
1. **Platform Detection**: Added `IsOpenSUSE16` property to
`PlatformDetection.Unix.cs` to detect OpenSUSE 16.0 and OpenSUSE Leap
16.0
2. **Networking Tests**: Added `ActiveIssue` attribute to skip
`Package_Unsupported_NTLM` test on OpenSUSE 16, which ships with broken
gss-ntlmssp 1.2 (similar to Ubuntu 24 and 26)
3. **Globalization Tests**:
- Added Unicode 17.0 IDNA test data and test infrastructure for ICU 78+
compatibility
- Updated test data factory to use appropriate Unicode version based on
ICU version
**Note:** Japanese calendar changes were intentionally excluded from
this PR as they constitute a breaking change that requires servicing
approval. The existing test fix from commit ff082da is sufficient for
OpenSUSE 16.0 compatibility.
# Customer Impact
None. Infrastructure-only change for CI/CD pipeline testing with test
compatibility fixes to ensure test suite passes on the new platform.
# Regression
No. This is a container version update to align with current OpenSUSE
releases, with corresponding test fixes to handle platform-specific
behavior differences.
# Testing
CI/CD pipeline validation through runtime-extra-platforms workflow. Test
fixes ensure that the existing test suite works correctly on OpenSUSE
16.0 by:
- Skipping tests that fail due to known platform limitations
- Updating test data to match newer ICU versions
# Risk
Low. Changes include:
1. Single line container version reference update in pipeline
configuration
2. Platform-specific test skips and data updates that don't affect
runtime behavior
3. All changes are test-only fixes that ensure compatibility without
modifying production code
4. Japanese calendar breaking changes were reverted to maintain
servicing policy compliance
# Package authoring no longer needed in .NET 9
IMPORTANT: Starting with .NET 9, you no longer need to edit a NuGet
package's csproj to enable building and bump the version.
Keep in mind that we still need package authoring in .NET 8 and older
versions.
