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 ?

Hello, you can see How the LSP works:
A language server runs in its own process, and tools like Visual Studio or VS Code communicate with the server using the language protocol over JSON-RPC.
@Anna Xiu-MSFT Thanks. Yes. language server is supposed to run in its own process.
I was exploring if there is a way to get this working in the same process as the extension. In my case, both language server and extension are written in C# and if they run in the same process, overhead of inter process communication can be avoided. Any leads on this will be greatly helpful.
Hello, I am sorry. I suppose it is hard to do. You can also send feedback here:

While it's technically possible to run a Language Server (LSP) as a DLL within the same process as a Visual Studio extension, it’s generally recommended to run the LSP in a separate process. This approach ensures better stability, isolation, and performance. Running the server separately prevents issues like crashes from affecting the entire devenv.exe process and provides better resource management (GitHub)(Telerik.com).
