Go to Definition fails over LSP for source generated files

[davidwengier]

Something is violating the expectations of the new Uri code:

Found while investigating #69732 and there is a link to a repro solution in there, but essentially execute a Go to Def via LSP to a source generated document.

I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

@davidwengier Nothing to do with the new URI code; this just isn't supported yet. The support is coming with #68771 and dotnet/vscode-csharp#5858.

Thanks, I was just about to comment that realisation, now that I've had time to think. I was so excited to get an exception investigating that competition issue, I just logged it right away :)

Feel free to close this as a dupe, though I have to ask - is that PR going to make things work in VS? Thats where I hit this, from a Razor file.

Oh I thought that was VS Code. Uh, regular VS will require some different work, so let's keep this open then.
