Psscor2 is a Windows Debugger extension used to debug .NET Framework (versions 2-3.5) applications. Psscor2 can help you diagnose high-memory issues, high-CPU issues, crashes, hangs and many other problems that might occur in a .NET app; in scenarios involving live processes or dump files. If you’re familiar with SOS.dll, managed-debugging extension that ships with .NET Framework, Psscor2.dll provides superset of that functionality. Most of added functionality helps you identify issues in ASP.NET. For e.g., Psscor2 provides the ability to view: managed call stacks (with source mappings); managed exception information; what types’re in managed heap and their reference chain; which ASP.NET pages’re running on which thread; contents of ASP.NET cache; and much more.
