for some time i've got a problem debugging my asp.net 3.5 Application with Visual Studio 2012. Each Time i want to observe which values are in an Collection,List or similar classes, Visual Studio hangs for some seconds and then for each Property of the Collection (like Count) there is no Value, but a message which says an timeout occured and i have to step further in the debugger, to activate it again. But when i step further (F10), Visual Studio hangs and i just can kill the w3wp.exe process and start debugging from beginning.
This Problem occurs only in my classic asp.net 3.5 application. Other Asp.net MVC or WinForms applications work just fine!
Anyone an idea?
