Microsoft.CodeAnalysis build error

[mcintyre321]

When testing out MSBuildCache on my solution, I am getting a build error related to Microsoft.CodeAnalysis 3.8.00, from one of our projects that itself references a difference Microsoft.CodeAnalysis version:

https://github.com/microsoft/MSBuildCache/blob/main/Directory.Packages.props#L29 references <PackageVersion Include="Microsoft.CodeAnalysis" Version="3.8.0" /> so it appears they are clashing?

NB I'm using dotnet build here - is it unsupported and I need a VS Install?

dotnet build -c Release

Currently the MSBuild Procjet Cache feature of MSBuild, which MSBuildCache depends on, only supported msbuild.exe (Visual Studio's MSBuild) and not dotnet.

Regarding the error message, I wouldn't think this is related to what you're referencing, as it's the task that's failing to load in the MSBuild process, which is unrelated to what your project references. Do you have a repro or a binlog you can provide so I can look deeper?

This is minimal repro

ConsoleApp1.csproj

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <OutputType>Exe</OutputType>
        <TargetFramework>net9.0</TargetFramework>
        <ImplicitUsings>enable</ImplicitUsings>
        <Nullable>enable</Nullable>
    </PropertyGroup>

  <PropertyGroup>
    <!-- In Azure pipelines, use Pipeline Caching as the cache storage backend. Otherwise, use the local cache. -->
    <MSBuildCachePackageName Condition="'$(TF_BUILD)' != ''">Microsoft.MSBuildCache.AzurePipelines</MSBuildCachePackageName>
    <MSBuildCachePackageName Condition="'$(MSBuildCachePackageName)' == ''">Microsoft.MSBuildCache.Local</MSBuildCachePackageName>

    <!-- Replace this with the latest version -->
    <MSBuildCachePackageVersion>0.1.318-preview</MSBuildCachePackageVersion>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="$(MSBuildCachePackageName)" Version="$(MSBuildCachePackageVersion)" />
    <PackageReference Include="Microsoft.MSBuildCache.SharedCompilation" Version="$(MSBuildCachePackageVersion)" />
  </ItemGroup>
</Project>

&"C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools\MSBuild\Current\Bin\MSBuild.exe" /t:Restore,Build

this is the binlog file

Maybe these steps are missing here?

@foriequal0 I tried that exact project and it worked fine for me.

I can reliably reproduce it on the three different environments (Windows, WSL, Ubuntu)

• First build without obj, bin directory always success.
• Second build always success.
• Build after dotnet clean always fail.

So,

1. Prepare ConsoleApp1.csproj mentioned before, Program.cs with static Main()
2. dotnet msbuild /t:Restore,Build will not error.
3. Second dotnet msbuild /t:Restore,Build also will not error.
4. dotnet clean then dotnet msbuild /t:Restore,Build will error.
5. Again, second dotnet msbuild /t:Restore,Build again will not error.
6. rm -rf bin/ obj/ then dotnet msbuild /t:Restore,Build will not error.
