Great information, Thanks!

I have disabled the MM.NET and MM Infragistics projects from being rebuilt (as per MM.NET Dev topic).
This allows me to keep a pulse on MM.NET while debugging my application.

I like the runtime debugging of symbols you described as follows:
"...Debug | Windows | Modules. Find the .dll that your .cs file belongs to, right click, choose "reload symbols", navigate to the .pdb (same name as the .dll) and choose it. You'll see now that symbols are loaded for that object."

Again thanks.
