I have only visual studio 2010 in my machine. But, when I look at the visual studio command prompt for "clrver", it shows two versions of CLR are installed in my machine - v2.0.5 and v4.0.3
From this link, I understand only the CLR version v4.0.3 should be available in my machine. http://msdn.microsoft.com/en-us/library/bb822049.aspx
But I am confused how I got v2.0.5. please explain?
