Psscor4 is a Windows Debugger extension used to debug .NET Framework 4 applications.
Psscor4 can help you diagnose high-memory issues, high-CPU issues, crashes, hangs and many other problems that might occur in a .NET application; in scenarios involving live processes or dump files.
If you are familiar with SOS.dll, the managed-debugging extension that ships with the .NET Framework, Psscor4.dll provides a superset of that functionality. Most of the added functionality helps you identify issues in ASP.NET.
Give Psscor4 a try to see just how useful it can be for debugging your .NET Framework 4 apps!
