Debugging a different version of .NET runtime

Copy the mscorwks.dll from the machine that has a different .NET version (than the version running on your debugging desktop) to the C:temp directory. Rename the file with the name “mscordacwks” and the version of .NET framework it came from, like this: mscordacwks_2.0.50727.1433.63.dll

In WinDBG, issue the following command: cdb -z c:tempmscordacwks_2.0.50727.1433.63.dll
