Intellisense in App_Code in VS2010

Question

Hi,

I've just upgrade my web application from vs2008 to vs2010, I create a new web app from vs2010, then copy across all the existing files from vs2008, then I add a new class file to App_Code folder, the intellisense is not showing up for everything and class etc is also not color in the right color. However, when I open the existing class I created earlier from vs2008, intellisense just working fine and all classes are in different color as well, if I make a copy of existing class, the copied class does not support the intellisense as well. However, if I shut my VS, and reopen it, they all appear to be support with intellisense for existing class, but once I created a new class, intellisense is not support.

Can you tell me what's wrong here? Thanks

I had the same problem after installing some update. The only solution was to reinstall vs2010.

Also try to reset settings:Tools->Import and Export Settings
