I have a vague idea Visual Studio allows you to run a second sandboxed instance where the add-in is being in fact loaded. That'd allow you to debug your add-in code and such.

Is this effectively possible? How would I go about doing that?

I'm currently using a single instance of Visual Studio. I'm having the problem that as I load and run the add-in, it won't allow me to compile again until I restart that instance of Visual Studio as there seems to be no way to unload the add-in. Even using two instances of Visual Studio wouldn't really help in here. There must be an easier way, how do you guys do it?

Thanks
