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

• Microsoft.CodeAnalysis.Razor.Workspaces
• Microsoft.CodeAnalysis.Remote.Razor
• Microsoft.VisualStudio.Editor.Razor
• Microsoft.VisualStudio.LanguageServices.Razor

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.
