I have a Visual Studio 2010 solution in which I am debugging two websites at the same time. Shortly after starting debugging and something gives an error, Visual Studio freezes and I get a tray icon and the message "Visual studio is busy. Microsoft Visual Studio is waiting for the internal operation to complete. If you regularly encounter this delay during normal use, inform about this Microsoft problem. Sometimes I can exit the iis express process through the tray icon and get Visual Studio to respond, but sometimes I have to kill the iisexpress task.
I linked the debugger from another instance to the problem instance until the moment of freezing and did not find anything useful.
I connected two separate instances of the debugger to the two iisexpress processes, and when I start debugging the site, the debuggers automatically join the iisexpress processes.
I found this article, but the links seem to address asp.net 3.5, and mine are 4.0 projects.
Visual Studio 2010 freezes when asp.net site debugging starts
Does anyone else experience this and know the fix?
