Description

I am working on an extension for Visual Studio. This implements a Language Server (LSP) also. Both extension and LSP are written in C#.NET. Is it a requirement that Language Server run in a separate process? Or can the Language Server be implemented as a dll and run in the same process as the extension and devenv ?

I am exploring if we can have both language server and extension run in the same process so that overhead of inter process communication can be avoided.
