I've been writing a VS .NET 2003 add-in for some time now and have
recently lost the abillity to debug my add-in.

I've tried uninstalling and re-installing my add-in using the generated
setup file and I've tried re-creating the commands.

For some reason whenever I try to debug my add-in the second instance
of Visual Studio runs but my add-in code is not loading, i.e. any
breakpoints set in the OnDisconnection method has the warning "The
breakpoint will not hit. No executable code is loaded at the current
location" (even though the add-in has clearly loaded in the second
instance of VS).

It seems as if the add-in being loaded is a different dll to the one
I'm trying to debug.

As anyone got any suggestions?

TIA
