Visual Studio Add-in Problem

I appologize if this is in the wrong forum, but i didnt see a forum dedicated to general Visual Studio issues...

I'm attempting to write an add-in which will allow me to integrate some custom applications with Visual Studio .NET... I've read the MSDN documentation on using the Add-In wizard, but seem to have an inconsistancy.. Once I create and build the add in, I 'start' the add-in which causes another copy of Visual Studio to start. However, the add-in is not visable in this 'child' copy of visual studio..

If I exit completely out of all Visual Studio contexts, then properly 'install' the add-in, it is now available to visual studio, however I am unable to rebuild the application due to file sharing issues (Which i expect...)

I understand why its preferable that the 'parent' VS *not* use the plug in, but for some reason when the child VS starts, it doesnt seem to be able to find the plugin...

Any help would be greatly appreciated..
