Assembly version of Microsoft.CSharp and System.Runtime.CompilerServices.Unsafe in 5.0 is older than the ones in 3.1?

[yyjdelete]

Tested with nightly builds of netcoreapp5.0, this will make app use out of box assembly instead of inbox ones when they are reference from other place.

Seems they are the only two assembly which have older version:

Microsoft.CSharp: 4.0.4 in 5.0, and 4.0.5 in 3.1 and nuget(4.7.0)
System.Runtime.CompilerServices.Unsafe: 4.0.5 in 5.0, and 4.0.6 in 3.1 and nuget(4.7.0)

@Anipik can you review these versioning dependencies?

It looks like you included these in 3.1 changes: dotnet/corefx@eaa4640

But they were missing from 5.0 changes:
dotnet/corefx#41723

This is blocking #2115 which in turn is blocking dotnet/sdk#3884.

The fix was reverted.

Fixed by #2354

@Anipik
Seems the buildin version of System.Runtime.CompilerServices.Unsafe in net5.0(preview) now has two AssemblyRef at the same time: System.Runtime 4.0.0.0 and 5.0.0.0. But it works well and seems nothing is affacted . So is this by design or another issue?
