Actually, why not just use the Strong type instead of the interface to begin with? I have a visual control that I'll use to display the RobotDeck. This control will be in a different assembly, our controls assembly. I did not want to introduce a dependency to our manufacturing assembly.

WebJul 15, 2013 · Generic constraints are not members of a type. But generic constraints are inherited on generic methods, right? That’s true, though what is inherited is the method and the constraint comes along with it. What is a bit odd is: generic constraints on methods are invisibly inherited when overriding, which has always vexed me.
