I came across a strange behavior of VS 2010 Ultimate and other version’s. I had VS 2008 Professional on my laptop and I tried installing VS 2010, it got installed each time but IDE crash was an issue. For instance, if I try to “Add a New Item” to the project IDE will crash and VS 2010 IDE will re-start.

I struggled with this for couple of days, and finally I thought of doing reverse installation. I.e, install VS 2010 and then VS 2008. So I Un-Installed Vs 2008 and VS 2010 (which was crashing) completely.

I did a fresh install of VS 2010, and then VS 2008, it works just fine.
