C# builds fail with `MissingMethodException` in v20240603.1.0 about runner-images HOT 10 OPEN

I'm seeing the same issue and found it's related to VS 2022 17.10. Looks like it's going to be patched soon per https://developercommunity.visualstudio.com/t/Cannot-build-any-project-after-update-to/10664111.

Thanks for everyone who uploaded the logs. Have a pretty good handle on the situation now. We’ll be patching 17.10 to fix this soon. In the meantime you can work around by installing the following package into impacted projects: Microsoft.Net.Compilers.Toolset at version 4.9.2.

HI @qwertie , Could you please help us to provide repro steps to investigate further.

Sorry, I don't think I'll have time. I was able to work around the issue by using DotNetCoreCLI@2 instead of VSBuild@1:

    - task: DotNetCoreCLI@2
      displayName: Build
      inputs:
        command: 'build'
        projects: $(buildSolution)
        configuration: Release

Hi @qwertie ,

your investigation is good , also look into your version compatibility and configuration values in the project and pipeline .

ex : .Net core or .net SDK versions . .Net 4.8 will support vs2019 and higher.
Default value of configuration is Release , verify it from your end

if you have any questions feel free to ask us , hope your workaround works in your case.
