Visual Studio hangs when changes are made to source codes in Asp.Net App_Code folder

My Visual Studio will ha开发者_如何学JAVAng everytime I make some small changes to the Codes in the App_Code folder.

I checked in the folder.. there are about 91 Files in 62 Folders.

Any suggestions on how I can improve its performance?

There's a similar report on the connect.microsoft.com site. The microsoft solution pointed to a plugin Document!X, but that didn't seem to cover all reported cases. There are a couple of comments which states that the problem occurs without the plugin (like this post).

Other people in my office have also confirmed that this problem is happening for them. Maybe it's a common plugin we all use. But, I'm hoping there is a setting we can change to prevent this.
