We are planning to remove IVT access to dotnet/roslyn from the following assemblies for 16.2 Preview 1:

• FSharp.Editor
• FSharp.LanguageService

These assemblies should be updated to operate correctly without IVT access to roslyn, or use an External Access assembly for all access to Roslyn internals. I will be assisting in the creation of the External Access layer if necessary for these components.
