[SUGGESTION] Option For (Go to definition) to Load Source Over DLL Metadata

Describe the feature you'd like

tl;dl - Omnisharp's F12 loaded referenced source whereas Language Server Protocol loads DLL's metadata

I work on many projects simultaneously. Some are dependent on others. I've always loved that Omnisharp allowed me to edit dependency source code directly in the dependent project. Unfortunately, LSP loads DLL metadata instead of the original source code, even though I add my projects via <ProjectReference />, not <PackageReference />. Can't say how I truly underappreciated a feature until it's robbed from you.

Now, to edit dependencies, I literally need to spin up another editor specific to that file's project, wait for LSP and everything to load just to get intellisense back, just so I can edit/review as easily as I've done during Omnisharp days.

Alternatives considered

Do what Omnisharp did -- have the editor load up the source file so I can simply make the changes I require.

No response

Start by tracing the F12/Go to definition path and how ProjectReference targets are handled, comparing the current DLL metadata behavior with the OmniSharp behavior described. Done means an option lets users load referenced source files instead of DLL metadata.
