There are two types of inheritance:

- Implementation: You inherit all the functionality. This is what you are talking about from VFP.
- Interface: You only inherit method signatures (so method names, parameters, return values). There is NO code in the parent class, only the signatures. You can do this in VFP too, but it isn't done very often, and then generally, only for rare cases with COM.

.Net supports both types of inheritance.

>I said this because in VFP you not only inherits the appearance but the code too, i want to know if it is true in asp.net and windows case and if there is any sample code or article you can recommend me about this.
