title: How do I create a GUI add in for excel?
body: <p>I've done some mucking around on Google but I still can't find what project this would be in Visual Studio. I want to create a GUI add in for Excel, for example a dock window on a ribbon with a windows form. What project would this be in Visual Studio? I have tried Excel add in but I don't know if this has the GUI component I'm looking for.</p>
