Description

Was working fine with image
Image: windows-2022
Version: 20241021.1.0
Included Software: https://github.com/actions/runner-images/blob/win22/20241021.1/images/windows/Windows2022-Readme.md
Image Release: https://github.com/actions/runner-images/releases/tag/win22%2F20241021.1

And stop working with image
Image: windows-2022
Version: 20241113.3.0
Included Software: https://github.com/actions/runner-images/blob/win22/20241113.3/images/windows/Windows2022-Readme.md
Image Release: https://github.com/actions/runner-images/releases/tag/win22%2F20241113.3

The code was the exact same an it just stop building with this error:

##[error]C:\Program Files\dotnet\sdk\9.0.100\Sdks\Microsoft.NET.Sdk.StaticWebAssets\targets\Microsoft.NET.Sdk.StaticWebAssets.Compression.targets(241,5): Error MSB4018: The "ApplyCompressionNegotiation" task failed unexpectedly.

System.ArgumentException: An item with the same key has already been added.

   at Microsoft.Build.BackEnd.TaskExecutionHost.Execute()
   at Microsoft.Build.BackEnd.TaskBuilder. <ExecuteInstantiatedTask>d__26.MoveNext()

It look like it's related to the Visual Studio Version (17.11 vs 17.12)

Would it be possible to have an image without DotNet 9?

Image version and build link

Image: windows-2022
Version: 20241113.3.0

Is it regression?

20241021.1.0

Expected behavior

Projects targeting .NET 8 (LTS) should continue to do so.

Actual behavior

Builds fails. Unable to use pipelines with DotNet8 - Blazor projects

Repro steps

dotnet/sdk#44784
dotnet/aspnetcore#57518

I was able to fix visual studio build task ( VSBuild@1) by specifying a stable SDK version in my global.json file. I set it to use .NET SDK 8.0.100, which bypassed the error completely.

for the DotNetCoreCli task ( DotNetCoreCLI@2) Im able to bypass it using

# Forces the pipeline agent to use the specified SDK version
- task: UseDotNet@2
  inputs:
    packageType: 'sdk'
    version: '8.0.100'
    installationPath: $(Agent.ToolsDirectory)/dotnet
  displayName: "Forces the pipeline agent to use the specified SDK version : 8.0.100"

But the problem persist when the blazor project have dependencies in DotNet Framework when using :

# Forces the pipeline agent to use the specified SDK version
- task: UseDotNet@2
  inputs:
    packageType: 'sdk'
    version: '8.0.100'
    installationPath: $(Agent.ToolsDirectory)/dotnet
  displayName: "Forces the pipeline agent to use the specified SDK version : 8.0.100"

- task: DotNetCoreCLI@2
  inputs:
    command: 'publish'
    publishWebProjects: false
    projects: '**/src/SSAMTA. BlazorApp/SSAMTA. BlazorApp.csproj'
    arguments: '--configuration Release --output $(Build.ArtifactStagingDirectory) /p:Version=$(myBuildNumber)'
    zipAfterPublish: True
  displayName: 'Build and Publish Blazor App'
