No, there are two different solutions.

I have a usercontrol in it's own solution in it's own folder. One project in a stand alone solution.

Then want to use the control it in a separate WinForms project. So in my WinForm project I created a reference to the user conrol. .Net makes a copy of the control's DLL in the WinForm's project Bin folder.

I then go back to the user control solution and make a change. The copy of the DLL containing the user control that's in the WinForm's Bin folder is now out of date.
