Can I safely remove ASP .NET MVC 2 from Visual Studio if I use ASP .NET MVC 3?

I'm trying to speed up my computer a little bit, and apart from these useful tips I'm trying to remove all Visual Studio extensions and add-ins that I don't use anymore.

I noticed I have both ASP .NET MVC 2 and 3 installed side-by-side, and I don't use version 2 at all.

Can I safely delete the old version, or does 开发者_JAVA技巧MVC 3 depend on MVC 2?

I don't want to mess up my working environment.

Yes.
MVC 2 and MVC 3 are completely independent.

Yes, I did this myself. In fact when I first installed MVC3 there was a known conflict whereby MVC3 won't work properly unless MVC1 is uninstalled first. Can't remember the details but yes you can remove MVC1 and MVC2 leaving MVC3 intact fine.
