We first build a public class library, which is referenced in both the main application and all extension class libraries, because we define the "Constitution" (interface) that is used to standardize the behavior of the component. This class library is named Commonlib, the code is as follows, very simple, no more than 10 lines.
This interface has only one method saysomething, we will use a few classes to implement it, each class is wri
