Errors not showing up until I open file where error occurs

[marcinjahn]

I noticed that csharp-ls will not show me errors in my repository until I open the files with issues manually.
E.g., if I change the name of some class (without using LSP rename feature), and that class is being instantiated in other files, I will not get any errors until I start opening each one of these other files.

Is it an expected behavior? In solutions with tens of projects, it's quite inconvenient.

I'm using csharp-ls with Neovim and the https://github.com/Decodetalkers/csharpls-extended-lsp.nvim.

Can confirm I can see this on VS Code, at the very least.
The issue is that csharp-ls does not implement the "workspace/diagnostic" LSP request and thus client is left to its own devices to accumulate diagnostics from the server as it sends them only for files that have been open recently.
