How to enable LSP mode on omnisharp-vscode client?

[patilarpith]

Looks like the default launch option on the VSCode plugin is not LSP mode. How do I configure the plugin to start Omnisharp server is -lsp mode and use LanguageServer client for communication?

I saw a config with the name razor.plugin.path. Just changing this to Microsoft.AspNetCore.Razor.LanguageServer.Common.dll works?

@patilarpith What are you trying to do? The C# extension doesn't use LSP to communicate with omnisharp. We therefore don't expose a way to start it in lsp mode.

Sorry for the late response.

I remember @mholo65 mentioning that he's able to run VSCode & OmniSharp-Roslyn in LSP mode. As I'm seeing some unusual behaviour with OmniSharp-Roslyn with monaco-languageclient, I was hoping the VSCode jsonrpc messages could provide some insight

@patilarpith as @rchande pointed out, OmniSharp-VSCode doesn’t run in LSP mode. You can however, quite easily create a custom VSCode extension that pkugs into OmniSharp-Roslyn running in LSP mode. See example here
