Visual Studio Freezing On Opening Project

Question

My Visual Studio seems to be freezing/lagging when I open a existing project. I have added NHibernate framework into my code and it seems to lag my computer (at least that's what I think). When I open other projects, I do not lag or freeze at all. The freeze is about 3- seconds to a minute, then it will open my project and it will just act very slowly, it might take 20+ seconds just to switch classes an 20+ more seconds just to type a single character into visual studios.

I was wondering if anyone has had this problem before. If so how did you fix it?

I can't really work on my code until this is fixed. Oh also, when is save the code, it freezes for a good minute or two also.

Answer 1

You can see exactly what VS is doing at any given moment, if you attach a debugger to the devenv.exe process and hit Break when it hangs. Then load the symbols from Microsoft Symbols server and show the call stack for the VS main thread.

I wrote a very detailed article about how to debug crashes and hangs here: http://blogs.msdn.com/kirillosenkov/archive/2008/12/07/how-to-debug-crashes-and-hangs.aspx

From the call stack it should be obvious what is causing the delay.

Answer 2

For me, removing the suo file (from the v14 sub directory) solved the problem...
