Answer 1

FYI, I've been working with Microsoft on a solution to this, and it as not as simple as NGENing the assemblies. There are two issues they are working on to address it, one of them is in the Roslyn compiler itself. You can track that bug here: https://github.com/dotnet/roslyn/issues/10413. If the other bug comes up on a public tracker, I will be sure to link to it.
