unrecognized objects using Facebook c# sdk samples

I'm starting to use Facebook c# SDK. By starting with a sample provided on the source(CSASPNETWebsiteRegistrationForm) I added the references and using Facebook and Facebook.Web but sentences like FacebookAppl开发者_运维技巧ication.Current.AppId are not recognized by Visual Studio.(not exist in the current context). Am I missing something? Sorry for my ignorance

You are missing references to Facebook.dll and Facebook.Web.dll. These are available in the source download in the bin folder.
