Here's what I did:
From VS2010 > new C# Project (from Other Project Types > Extensibility > Shared Add-in) > some basic configuration in the Connect class
After that I set in the project properties > debug > start external program, the path for winword (C:\Program Files (x86)\Microsoft Office\Office12\WINWORD.EXE)
When creating a shared add in, the setup files are in a separate project, in the same solution. so i did a build for the add-in, and installed it.
when i start word (separately or from Start with debug from visual studio) the add-in runs fine, but it can't seem to hit any breakpoints?
If I modify something and do just Build, when i start word again, the changes are there, so it must be the correct dll that word is loading
Question is of course, how do i get breakpoints to work?
