The error message is: "CSC : error CS9057: The analyzer assembly '/home/build/powershell/src/System.Management.Automation/SourceGenerators/PSVersionInfoGenerator/bin/Linux/netstandard2.0/SMA.Generator.dll' references version '4.9.0.0' of the compiler, which is newer than the currently running version '4.8.0.0'."

Steps to Fix:
1. Update the compiler to version 4.9.0.0 or higher.
2. Ensure all dependencies are compatible with the new compiler version.
3. Rebuild the project to verify the error is resolved.

I went through the history and ran some additional tests; here is a summary of my findings:

• Despite trying to update versions, the latest PowerShell appears to depend on a dotnet compiler version that's newer than the latest available (still in prerelease phase) and it's not something that we build.
• This was previously discovered and deferred to later with the hopes that updates would solve it. This does not appear to have been the case yet.
• Phil wrote a good summary of our options. I've replicated them below as potential next steps.
• The latest Powershell and .NET builds are from mid August. Perhaps a new version is around the corner with .NET 9 now up to RC1.

Next steps and options:

One way or another, this will require more in-depth conversations to decide which path to take. Options include:

• Build a new SDK package from a different source to the runtime so we have an SDK version newer than that packaged currently?
  • May make sense as I think we're doing this already for other packages. But as far as I can tell, this still won't solve the fact that it wants a compiler version only found in the prerelease SDK.
• Patch the SDK requirement in powershell and hope nothing breaks?
  • Doesn't seem like best practice, and at best a bit of a hacky workaround without proper testing.
• Propose an upstream patch to powershell to not depend on an SDK version that is not packaged by Wofli or Ubuntu
  • Not sure why but it doesn't seem like this is really happening or reported elsewhere with powershell specifically, so this may make sense to do regardless.

• https://github.com/PowerShell/PowerShell/releases/tag/v7.4.5
  • Shows minimum .NET SDK version of 8.0.400, which appears to require compiler version 4.9.0.0 based on running the image build.
• https://github.com/dotnet/dotnet/releases/tag/v8.0.8
  • I would think since 8 > 400, this would provide the required compiler, but it seems to only provide version 4.8.0.0.

  • This help article discusses the exact error we're getting. .NET 9 will "detect and automatically adjust for this problem scenario", meaning that once it's out of prerelease and we can use it, it may resolve the issue all by itself.
