Where does the bug appear (feature/product)?

Cursor IDE

Describe the Bug

A critical feature is using “Go To Definition” in c# . I Tried F12, Ctrl+Click, Right Click - none of them work.

I tried:

Uninstalling extensions
Reinstalling extensions (and reloading)
Uninstalled Cursor, cleared app data
Doesn’t work

Steps to Reproduce

As soon as I open Cursor, I’m unable to use “Go To Definition”. I see that the shortcut is mapped, but pressing F12 (or using any other method) doesn’t do anything

Expected Behavior

Hey! I had the same issue ,not 100% sure which step fixed it, but here’s what I did:

Installed the DotRush extension.

Opened the command palette (Cmd/Ctrl + Shift + P) and ran:

→ DotRush: Pick Project or Solution files

(selected a file manually).

Then used Developer: Reload Window to refresh everything.

Initially, “Go to Definition” still didn’t work, but after selecting the project through DotRush and reloading the window, it started working normally again (F12, Ctrl+Click, etc).

It seems the C# language server wasn’t properly loading the project before DotRush pointed to the correct file.
