So I've still got my IPerson interface here, but I've simplified it, with just first name and last name. And I've got an abstract class called Employee. Because it's abstract, I can't create an instance of the Employee class, but I'm defining it as a base class for others to implement. So we've got our properties from the interface. We've got a StartDate that's a property. And then we get into the abstract part here. Now I have properties and I have methods. And if you recall, when we do properties that get and set, though, we often just simplify them like I've done here, actually result in methods. We have a get EndDate and a set EndDate method. So those, just like regular methods, can be marked as either virtual or abstract. Now abstract, as we see here for the ProcessPayroll method on line 24 means that this class, the base class does…
