Visual Studio Debugger not attaching to Unity

Question

I\'m having issues getting Visual Studio\'s debugger to attach to Unity - editing and compiling scripts inside VS is working fine - however, when clicking \"Attach to Unity\

Answer 1

I had the same problem, except that the tool didn't print any unity process... Uninstalling Xamarin as well didn't help, and in fact I was just not able at all to attach unity throw the tool. (Attach process did worked, but no breakpoint in code can be reached).

In fact, it was because I renamed "Unity.exe" to Unity "5.3.4f1.exe".

Visual Studio Tools for Unity need to attach to the process Unity, and no other name can be handle for now.
