I have a Web Application Project that I'm working on.

My solution looks like this :

./MyProject/
./MyProject/dataobjects.cs <- no intellisense
./MyProject/sqlquerying.cs <- no intellisense

./MyProject/default.aspx <- intellisense works here
./MyProject/default.aspx.cs <- intellisense works here
./MyProject/mypage.aspx <- intellisense works here
./MyProject/mypage.aspx.cs <- intellisense works here

Visual Studio 2010 doesn't give me any intellisense options when I work on non-code-behind files like Business Logic Layers and Data Logic Layers . In VS2008, I placed these files in the App_Code folder and intellisense worked fine.

What can I do? Is there a specific folder I need to put these files in to get intellisense?
