Interfaces

The way you interact with a personal computing device is changing and is about to change even more with lots of touching and even a little hidden video.

Building small applications from scratch is easy enough with almost any available programming technology. However, if you are assigned the task to build large applications and have the requirement to re-use code either now or tomorrow, you need to be a lot more careful. Microsoft has ready-made patterns that help you build complex Windows Presentation Foundation applications with reusability and componentized design in mind.

Stop writing more code than needed. You can streamline your code if you use interfaces. You will be able to write simpler, more flexible, and more maintainable applications when you apply interfaces.

The IDisposable interface can be used for far more than just the releasing of memory and resources. Learn how to use the interface to ensure that post conditions of code blocks are always met.

Learn about interfaces and how they inherit in C#.

Multiple inheritance is not possible in C# using classes; however, you can implement multiple interfaces. This is a simple example of inheriting characteristics of multiple interfaces.
