Fixes#91131

This is a stripped down version of 9.0 (main) PR #91160 with more targeted fix and same unit test.
Unlike #91160 it doesn't try to fix which status code is reported and always reports Unsupported. This is in line with the .NET 7 behavior.

Customer Impact

Regression against 7.0.
Due to refactoring in the space, on Android and tvOS we started throwing PlatformNotSupportedException for CredentialCache.DefaultCredentials instead of returning StatusCode = HttpStatusCode.Unauthorized (401) as we did in 7.0.

For context:

  • It applies only to Android and tvOS, because those are the only platforms using managed NTLM implementation (introduced in .NET 7.0).
  • In 6.0 and earlier we already threw PlatformNotSupportedException for this case, but it was inconsistent across platforms - it sometimes threw Win32Exception or even internal GssApiException.
  • Refactoring in 8.0 removed several layers of abstractions in NTLM authentication and simplified the space, but as a side-effect removed general try-catch which allowed HttpClient to handle these exceptions and return 401 HTTP status code. How it should behave, depends if one looks at it from the low-level API perspective (NegotiateAuthentication), or from higher-level API perspective (HttpClient) - see discussion in Android NTLM: Empty Credentials now throws PlatformNotSupportedException #91131.

Testing

Unit test is added to simulate the customer scenario. It fails without the fix and succeeds with it.
E2E validation by customer on private build of 8.0 branch - see #91131 (comment)

Risk

Low

Affects only managed NTLM implementation, which is used only on Android and tvOS. Changes only error handling, not main code path.

Fixes#91131
This is a stripped down version of 9.0 (main) PR #91160 with more targeted fix and same unit test.

Unlike #91160 it doesn't try to fix which status code is reported and always reports Unsupported. This is in line with the .NET 7 behavior.
Customer Impact
Regression against 7.0.

Due to refactoring in the space, on Android and tvOS we started throwing PlatformNotSupportedException for CredentialCache.DefaultCredentials instead of returning StatusCode = HttpStatusCode.Unauthorized (401) as we did in 7.0.
For context:
  • It applies only to Android and tvOS, because those are the only platforms using managed NTLM implementation (introduced in .NET 7.0).
  • In 6.0 and earlier we already threw PlatformNotSupportedException for this case, but it was inconsistent across platforms - it sometimes threw Win32Exception or even internal GssApiException.
  • Refactoring in 8.0 removed several layers of abstractions in NTLM authentication and simplified the space, but as a side-effect removed general try-catch which allowed HttpClient to handle these exceptions and return 401 HTTP status code. How it should behave, depends if one looks at it from the low-level API perspective (NegotiateAuthentication), or from higher-level API perspective (HttpClient) - see discussion in Android NTLM: Empty Credentials now throws PlatformNotSupportedException #91131.
Testing
Unit test is added to simulate the customer scenario. It fails without the fix and succeeds with it.

E2E validation by customer on private build of 8.0 branch - see #91131 (comment)
Risk
Low
Affects only managed NTLM implementation, which is used only on Android and tvOS. Changes only error handling, not main code path.

Fixes#91131
This is a stripped down version of 9.0 (main) PR #91160 with more targeted fix and same unit test.

Unlike #91160 it doesn't try to fix which status code is reported and always reports Unsupported. This is in line with the .NET 7 behavior.
Customer Impact
Regression against 7.0.

Due to refactoring in the space, on Android and tvOS we started throwing PlatformNotSupportedException for CredentialCache.DefaultCredentials instead of returning StatusCode = HttpStatusCode.Unauthorized (401) as we did in 7.0.
For context:
  • It applies only to Android and tvOS, because those are the only platforms using managed NTLM implementation (introduced in .NET 7.0).
  • In 6.0 and earlier we already threw PlatformNotSupportedException for this case, but it was inconsistent across platforms - it sometimes threw Win32Exception or even internal GssApiException.
  • Refactoring in 8.0 removed several layers of abstractions in NTLM authentication and simplified the space, but as a side-effect removed general try-catch which allowed HttpClient to handle these exceptions and return 401 HTTP status code. How it should behave, depends if one looks at it from the low-level API perspective (NegotiateAuthentication), or from higher-level API perspective (HttpClient) - see discussion in Android NTLM: Empty Credentials now throws PlatformNotSupportedException #91131.
Testing
Unit test is added to simulate the customer scenario. It fails without the fix and succeeds with it.

E2E validation by customer on private build of 8.0 branch - see #91131 (comment)
Risk
Low
Affects only managed NTLM implementation, which is used only on Android and tvOS. Changes only error handling, not main code path.
