Lag caused by Microsoft .NET Framework [CLIENT]

I found out that lately a lot of peolpe have had heavy visual lag issues, after an in depth research on the net I found out that Microsoft .NET Framework might actually be the problem. I have been lagging for at least 4-5 patch continuosly, after unistalling Microsoft .NET Framework as suggested in a post I managed to recover all my FPS and game is no longer laggy. I'd suggest there should be further investigation about this issue/incompatibility.
