@manodasanW the test failure in Debug x64 seems unrelated, maybe transient? Could you re-trigger that CI job? 🙂 |

Extracted from #1399
Description
This PR adds a new
MarshalStringAPI:This allows marshalling an
HSTRINGto aReadOnlySpan<char>value, without allocating a temporarystring. The "Unsafe" suffix matches the naming convention in the BCL for methods that are not safe when misused. In this case, callers have to make sure not to escape the returnedReadOnlySpan<char>value outside of the scope where theHSTRINGis valid.Developers can use this where appropriate, and we can also use this in eg. marshalling stubs in the future. Once we update the projections to require C# 11, we can also restore #1399 and leverage this API there as well.
