Script to load sos within Windbg based on .NET Framework version

I often debug  .NET Framework v 2.0 / v 4.0 code within windbg. In v 2.0 the main clr dll was called “mscorwks.dll” and in v 4.0 it is called “clr.dll”.  As many of you are aware , to load sos in v 2.0 we would have to enter “.loadby sos mscorwks” and in v 4.0 it would be “.loadby sos clr” . This was a pain for me. Came up with a script to automate loading sos based on clr version !
