WindDBG : load right extensions

2012-07-13 2 min read Debug

In order to debug .NET applications, Microsoft provides a tool called WinDBG available in “Windows SDK”.

WinDBG is a native debugger and need additional extensions to work with .NET application. These extensions are different based on technology and .NET version (Silverlight / WPF / .NET 2.0 / .NET 4, etc.).

SOS

SOS.dll (Son Of Strike) is a DLL provided by .NET Framework and is available in folder :

C:\Windows\Microsoft.NET\Framework\

The DLL loading is slightly different if your application is a classic .NET 4 application or Silverlight application. Actually Silverlight uses only a subset of .NET Framework based on coreclr.dll and not clr.dll (mscorwks.dll for .NET 2.0). The extension module to load is not the same (clr for .NET 4 and coreclr for Silverlight).
