Course 70095: Inheritance, Interfaces, and Resource Management

Introduction This course introduces inheritance and interfaces in the Microsoft® .NET Framework and how you can use them to simplify complex problems, reduce code duplication, and decrease development time. All applications use resources, managed or unmanaged. During application development, resource management is important, and this is simplified by the .NET Framework. In this course, you manage the lifetime of objects and control resources so as to ensure that your applications do not hold resources longer than is necessary for the operation of the application. Objectives At the end of the course, students will be able to:

• In this course, you will inherit from classes and implement interfaces. In addition, you will manage the lifetime of objects and control resources.
