Cannot go to definition of generated files

[YelovSK]

I am generating some code with incremental generators. Trying to go to the definition does not do anything in Zed with OmniSharp or Roslyn.

This is the Roslyn log when I try to go to the definition:

In the attached video, you can see it doesn't work in Zed, but works in e.g. VS Code with the C# extension.

To support this, the ability to fetch content of virtual documents via LSP will need to be added to Zed. Then, dotnet/roslyn#80276 will need to be implemented in Roslyn.
