  • Article

PSSCOR extension is a debugger extension which is super-set of SOS.DLL. It is used for debugging .NET issues with WinDBG, such as high memory / CPU usage, crashes, etc...

We have released PSSCOR2 for .NET 2.0 related issues before and we were using PSSCOR4 for a long time in Microsoft for .NET 4.0 related issues and now it is available for public download.

You can download PSSCOR4 extension from Microsoft download page:

Psscor4 Managed-Code Debugging Extension for WinDbg
https://www.microsoft.com/downloads/en/details.aspx?FamilyID=a06a0fea-a4d4-434e-a527-d6afa2e552dd

Here is the overview taken from the same page:

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. For example, Psscor4 provides the ability to view:

  • managed call stacks (with source mappings)
  • managed exception information
  • what types are in the managed heap and their reference chain
  • which ASP.NET pages are running on which thread
  • the contents of the ASP.NET cache
  • and much more.

Enjoy PSSCOR4 :)
