[severity:I'm unable to use this version]
1. Create a .NET 5 console app. I am using .NET SDK 5.0.302.
2. Set the TFM to target Windows to pull in the Windows targeting package: net5.0-windows10.0.19041.0
3. You will see the Windows SDK reference pack with the properties:

4. Override the version by setting the property, for example 10.0.19041.17
5. You will see that the Microsoft.Windows.SDK.NET.Ref Version is updated, however the version of the binaries (Microsoft.Windows.SDK.NET, WinRT.Runtime) are not updated in the UI.

I need to close and reopen the solution for these versions to be updated.
