@jaredpar Jared, would it be possible to run some Roslyn tests to ensure that Roslyn doesn't experience any unexpected failures with this change? |

We need to add the project changes to version this and build it. To the SRM src csproj add <GeneratePackageOnBuild>true</GeneratePackageOnBuild>
<ServicingVersion>1</ServicingVersion> |

I went ahead and did this. |

Backport of #63305 to release/6.0
/cc @davidwrighton
Customer Impact
Enable development of the
CreateSpan<T>support feature within the Roslyn compiler during the .NET 7 timeframe. For complex packaging reasons, the Roslyn compiler cannot take a dependency on bug fixes added to in a development release of the .NET system, so fixes required to develop vNext Roslyn need to be backported to a servicing release of .NET.Testing
The backport includes tests to validate that the MappedFieldStream is aligned as it should be.
Risk
Low risk. This will change the output of various compilers by adjusting padding, but not in a way which is concerning. The Roslyn team has confirmed that this sort of difference is acceptable.
