New Post: How to Get Breakpoints Working?

I can't get the breakpoints to work on a NO Word addin. I created the addin using the NO Toolbox. I am using the project created by the toolbox, no mods. I load the project into VS 2015 Community and set a breakpoint on the About click . I run it using F5. Word 2010 loads and the addin installs. I click on About and the message shows the it doesn't breakpoint. If I debug a simple C# program it breakpoints fine. I have never debugged a DLL. Is there something I need to set?

I cleaned the project and built it again. I checked the debug properties and everything appears right, at least to me. I set breakpoints on other lines and nothing works.

Any suggestions are appreciated.
