EnsureNETCoreAppRuntime validation failed on 16.8 Preview 4

See original GitHub issue

When an ASP .Net Core web project has RID <RuntimeIdentifier>win7-x64</RuntimeIdentifier>, then project load shows the following error

Project is targeting runtime ‘win7-x64’ but did not resolve any runtime-specific packages for the ‘Microsoft.NETCore.App’ package. This runtime may not be supported by .NET Core.

and the above error is from "C:\Program Files\dotnet\sdk\NuGetFallbackFolder\microsoft.netcore.app\2.1.0\build\netcoreapp2.1\Microsoft.NETCore.App.targets"

I notice this error happening only on 16.8 Preview 4 build. (Version 16.8.0 Preview 4.0 [30509.233.main]) and the Dependencies tree shows some warning

Repro Steps:

Create a ASP .Net Core project and then add win7-x64 as runtime identifier.
unload and reload the project.

This will be fixed in .NET SDK 5.0.101, which I believe will go out together with VS 16.8.3. So no need for a binlog or anything at this point.

I’m seeing this issue since upgrading to VS 16.8.2 for all projects on netcoreapp3.1. Currently not seeing any runtime issues; workaround provided above does hide the error - I would like to remove <EnsureNETCoreAppRuntime>false</EnsureNETCoreAppRuntime> sooner rather than later
