Failures with Cannot implicitly convert type 'System.ReadOnlySpan<int>' to 'System.Span<int>' seem related.

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

With this roslyn update, the generated iterator state machine
for this test includes a Dispose method which assigns null to the
array, inhibiting dataflow analysis.

@copilot fix this error: src/libraries/System.Net.Http/src/System/Net/Http/Headers/HttpHeaders.cs(1209,42): error CS8620: (NETCORE_ENGINEERING_TELEMETRY=Build) Argument of type 'string[]' cannot be used for parameter 'values' of type 'Span<string?>' in 'void HttpHeaders.ReadStoreValues<string?>(Span<string?> values, object? storeValue, HttpHeaderParser? parser, ref int currentIndex)' due to differences in the nullability of reference types.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

With this roslyn update, the generated iterator state machine
for this test includes a Dispose method which assigns null to the

@copilot fix this error: src/libraries/System.Net.Http/src/System/Net/Http/Headers/HttpHeaders.cs(1209,42): error CS8620: (NETCORE_ENGINEERING_TELEMETRY=Build) Argument of type 'string[]' cannot be used for parameter 'values' of type 'Span<string?>' in 'void HttpHeaders.ReadStoreValues<string?>(Span<string?> values, object? storeValue, HttpHeaderParser? parser, ref int currentIndex)' due to differences in the nullability of reference types.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).

Fix MemoryMarshal.Cast implicit conversion error after Roslyn update (#…
df29b24
…121414)
The Roslyn 4.14.0 compiler update introduced stricter type checking for
`MemoryMarshal.Cast` when called directly on arrays, now returning
`ReadOnlySpan<T>` instead of `Span<T>`.
## Changes
- **JsonDocument.MetadataDb.cs**: Explicitly convert byte array to
`Span<byte>` before casting to `Span<int>` to preserve write access
```csharp
// Before
Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase);
// After Span<int> newDbInts = MemoryMarshal.Cast<byte, int>(newDatabase.AsSpan());
```
The writable span is required since the code modifies elements via
`newDbInts[i] -= locationOffset`.

Fix CS8620 compiler error in HttpHeaders after Roslyn 4.14.0 update (#…
6e2757c
…121601)
Fixes compilation error introduced by Roslyn 4.14.0's stricter type
checking for array-to-span conversions.
main PR: #121343
# Description
Roslyn 4.14.0 no longer allows implicit conversion from `string[]` to
`Span<string?>`. Fixed by explicitly converting arrays to spans in
`HttpHeaders.GetStoreValuesIntoStringArray`:
```csharp
// Before
ReadStoreValues<object?>(values, info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
// After ReadStoreValues<object?>(values.AsSpan(), info.ParsedAndInvalidValues, descriptor.Parser, ref currentIndex);
```
# Customer Impact
Blocks servicing release builds. No runtime behavior change.
# Regression
No - compiler enforcement tightening from dependency update.
# Testing
Verified compilation fix. No functional changes to test.
# Risk
Minimal. Surgical two-line change converts array to span where method
signature already required it. Identical pattern to fixes in #121414 and
BigInteger.cs (46bb931).
