ASP.NET MVC cannot scaffold with types from a referenced assembly

Question

I am building my very first MVC project and I would like to use scaffold a new view using custom types that exist in a referenced assembly.

Is scaffolding only available for locally declared types?

I add a new view via the "Add View" dialog, I choose to "Create a strongly-typed view" and I pick my class type in the "View data class" drop-down list but the "View content" drop-down list is disabled.

Does anyone know if I am doing something wrong?

Thanks alot!
