can a dll file be called somethiong else

We could have multiple implementations of this interface in our main project or in seperate assemblies that would all look similiar to this class with slightly different implementations: (Of course, in a real application the interface for the plug-in would probably be much more complex but we'll keep it simple here to keep the focus on the technique.) Once we have a class that implements this interface, it can be 'plugged' into the host application by dropping the containing dll into a specified folder which provides the host application with a 'pluggable' implementation of the exposed interface.įor this article we'll be using a the following very simple interface that will allow us to build plug-in components that the host can use to perform a calculation on two integers and expose the symbol representing the calculation. The host will then load different implementations based on some criteria that we'll be choosing. Using this technique, we will use the standard GOF State Pattern by having a host application expose a piece of functionality as interface.
