User-controls development for Sharepoint

Many people develop custom user-controls for Sharepoint. When doing so, I often found many a developer deploying each change they make, attaching the debugger to the w3 process in order to debug their code. However this is not required, simply create a testpage in you project, then add your usercontrol to that testpage, F5 and voila, no need to deploy all the time to test. You also avoid A LOT of iisreset. Hope this helps a few.
