C# Snippets - Get CLR Version Info

While having a chit chat with my friend, our discussion got on with, the different versions of C# and CLR and how do they stack up. For me its was something new to hear that the CLR version 3 actually didn't exist at all, instead Microsoft had released service packs for CLR, to contain the changes that came in .NET Framework v3.0 and above. Here is a list of C# and CLR version mapping details which I had collected from other sources.
