GoContextMenu and ASP.Net

I’m looking into the processor sample app for context menu functionality. The code for context menu was originally commented out, but when I try to enable it compilation fails. It seems there is no such thing as GoContextMenu object in the GoWeb assembly.
I want a context menu to popup when user right-clicks a node.
I have only access to the evaluation version at the time.

That new functionality has been implemented for version 2.5.
