<ProjectGuid> ignored ?

[goswinr]

I undestand that a <ProjectGuid> is no longer needed or desired.
But it seems that even if it is present it is silently ignored. Is that intended?
Where would I look for the official documentation of this behavior?
I need to have a Guid in my dll in order to load it as a plugin into another App.
I had to look at the IL to see that the Guid is missing. I got it back via an AssemblyInfo File.

The [assembly: Guid(...)] attribute determines an assembly's GUID.

In .NET Framework, the project GUID was synchronised between .sln, .csproj and AssemblyInfo.cs.

In SDK-style projects, the project GUID only exists in the .sln file. Looking at the generated obj\Debug\netstandard2.0\MyProject.AssemblyInfo.cs will show there is not [assembly: Guid] attribute for the assembly. Each time you build your project, a different Guid will be used. If you require a specific Guid, you must add the attribute yourself.
