MonoDevelop debugging always hangs when attempting to attach to Unity

I’m having this issue where when I attempt to debug some code using Monodevelop I consistently get a hang when attempting to attach to the unity process. I have gotten it to work once or twice, but in general it pretty much never works.

Coworkers have no issues debugging the same project on both PC and Mac, so I don’t think it’s an issue with my project.


Repro steps:

1. Launch Unity
2. Launch Monodevelop
3. In Monodevelop Run->Attach To Process
4. Clicking attach...
