Support for source generators?

[hutterm]

in a project using a source generator I find that a go to definition results in

is there any way to support this?

tried updating to opts.roslyn_version = "4.9.0-2.23563.2" but that alone doesn't do it

I would appreciate if you could provide a sample project (.cs and .csproj files) to quickly reproduce and try to fix this.

[hutterm]

here is a sample project. go to definition on the Prop fails

Edit: Likely related from upstream: dotnet/vscode-csharp#6426

I think this issue is keeping me from searching for workspace symbols using telescope in a project that uses source generators, meaning I would need to search for files instead.

I think a band-aid fix for now would be for this to ignore invalid URIs if possible, that would at least allow searching for non-generated symbols.

I'd be interested in fixing this, as otherwise this client is a lot better than omnisharp, but I have no idea how.

I've updated my version to 4.10.0-1.24058.1, which is the version currently tracked by the vs-code plugin. This fixes the issue with workspace symbols throwing an error in telescope for me, but the resulting file is empty.

Attempting to navigate to implementations on a partial type with source generated implementations still throws the following error:

Error executing vim.schedule lua callback: ...myNeovimPackages/start/trouble.nvim/lua/trouble/util.lua:158: ENOENT: no such file or directory: source-generated:///Godot.SourceGenerators/Godot.SourceGenerators.ScriptMethodsGenerator/Schnozzle.Logging.Logger_ScriptMethods.generated.cs

Edit: Annoyingly, this still fails if you use a goto_reference on something that has a source generated member...

I'd be curious if this will work for something like CommunityToolkit.MVVM too. I'd love to use this plugin for MAUI development
