Go-to-Definition from C# into F# always opens metadata instead of real source

[oseifrimpongg]

I’m working in a mixed solution that contains both C# and F# projects.
When I navigate from C# into an F# type using F12, VS Code always opens the metadata-as-source view, even though the actual .fs file exists in the same solution.

Expected behavior:

F12 should jump to the real F# source file when the type is defined in a referenced F# project.

Actual behavior:

F12 consistently opens the generated metadata view instead of the .fs implementation.

Is there a setting that does this? I have done some research and toggled a couple of the settings, however, none of them are able to solve my problem. This feature works perfectly in Rider, however, I'm not the best Rider fan and would want to have my flow in VSCode.

This has been an open issue for years on the C# plugin unfortunately dotnet/vscode-csharp#1623

Is there any way I can help (absolute noob here btw :)

I don't have a good handle on the whole shape of the problem anymore. It involves trying to contribute this to vscode-csharp, but there are a lot of technical (sharing project information) and political (getting the maintainers of vscode-sharp to care) hurdles.
