I have this form class which starts like this:

Namespace Framework

    Public Class Robot
        Inherits System.Windows.Forms.Form

Then, from the client application, I want to benefit from it such as:

Public Class Main
    Inherits Framework.Framework.Robot

There must be something I am missing here because I get:

Base class 'Framework.Framework.Robot' specified for class 'Main' cannot be different from the base class 'System.Windows.Forms.Form' of one of its other partial types.
