[RESOLVED] VS 2008 express: intellisense not showing namespace

I have a typed data set in the app_code folder. I created a new class (class1.cs) inside the app_code folder, and for some reason, when I type:

using SomeNameSpace1.someNameSpace1

it's as if the above namespace does not exist: "SomeNameSpace1" or "SomeNameSpace1.someNameSpace2" does not exist. If I create the class file outside of the app_code folder, then the namespace DOES exist. What am I missing?

By the way, the namespace i'm trying to use is the typed data set that was auto-generated.

I figured it out, the Build Action was in "Content" instead of "Compile".

Thanks for posting the solution Ben, I think this would be a common problem and it is good to have it documented here.
