[LSP] Adding new files to the project?

[vincentwoo]

Hi there,

I have omnisharp-roslyn running in -lsp mode. I initialize omnisharp in a directory with a sln and csproj file, along with a Program.cs lying around. I find that if I change Program.cs and send textDocument/completion requests, I get results back.

I find also, however, that if I save, say, Foo.cs, and notify omnisharp about it with a textDocument/didOpen subsequent textDocument/completion results return only empty array.

Is there some other call that omnisharp requires in LSP mode to register new files in the current directory?

Anyone know anything about this? Still seems to be happening as of latest release. What sequence of notifications must be sent to the LSP to inform them of a new .cs file? We are sending didOpen / didChange.

I also find that I can only get publishDiagnostics results from the LSP regarding a file if that file is present when the LSP boots up - if I create a file (and inform the LSP of the file through didOpen/didChange) it does not ever emit diagnostics events for that file.

I believe sync issues (at least partially) are fixed with:

• Update OmniSharp.Extensions.LanguageServer to "0.14.2" to fix synchronisation Update OmniSharp.Extensions.LanguageServer to "0.14.2" to fix synchronisation #1791

The underlying issue was in LSP library:

• Fix TextDocument synchronization for LSP3 csharp-language-server-protocol#199
