Version Used: VS 16.9.0 Preview 3.0

Steps to Reproduce:

1. Create 2 projects with roslyn code generators, A and B. Projects A and B use the same roslyn analyzer
   

2. Project B references Project A.

3. Try to open both of the generated files with the same name.

Expected Behavior: When opening the generated files, file A should be different from file B

Actual Behavior: Both file links open the same physical file. Additionally, when using F12 on members of the generated files, you will be pointed to the same file whether you are trying to view A.GeneratedMember or B.GeneratedMember
