Login using Facebook, missing namespace?

Question

I am trying to integrate a login with facebook feature in my website and following this article .

This line gives me a "Missing directive or assembly reference error. The type or namespace could not be found." I have placed the binaries as well.

API api = new API();

Which namespace contains the API class or is it no longer supported?

Answer 1

Facebook API class doesn't exist anymore

Answer 2

If you're using Visual Studio, press Ctrl + . while your caret is within API to see what namespaces contain the API class.
