MSBuild does not resolve WindowsBase correctly

See original GitHub issue

Describe the bug

I am working with third-party components (DevExpress) and their new release based on .NET 6 appears to have exposed a potential bug in MSBuild’s assembly resolution logic. There appears to be a versioning conflict between two WindowsBase DLLs in the WindowsDesktop and NETCore SDKs. For further details, please see this public support ticket. In particular, this reply.

The issue applies to both .NET 6 and .NET 7 WindowsDesktop projects.

To Reproduce

Here is a sample project you can build to reproduce. Just build it and look in the Visual Studio build output to see the below lines.

Maybe dotnet/sdk would be a better fit for this. There are some issues that sound related, for instance WindowsBase NETCoreApp vs WindowsDesktopApp Do not autoreference WindowsBase.dll in Microsoft.NetCore.App

@hyke123 It has not been resolved as of the latest VS version (17.5.3). No one from MS has commented here on the issue yet - still waiting.👀
