CS8032: Build task may fail using Azure DevOps CI/CD pipeline

[Benny56]

The build task used in a Azure DevOps CI/CD pipeline may fail with a #CS8032 warning when the default .NET compiler is invoked.

It worked for me to make sure that the latest compiler version is used.
I have added to my .csproj:

<PackageReference Include="Microsoft.Net.Compilers" Version="3.8.0">
  <PrivateAssets>all</PrivateAssets>
  <IncludeAssets>runtime; build; native; contentfiles; analyzers</IncludeAssets>
</PackageReference>

Finally the project was built.
