title: Find all reference on all projects in solution
body: <p>My solution contains multiple projects (say P1, P2). In project dependencies, I set P2 to depend on P1, so P2 uses some classes in P1. When I do a Find All References on a class/method of P1, the result shows only the occurences in P1; not the occurences used in P2. Is there a way to have Find All References work on the entire solution?</p>
