Advanced C#: Design Patterns & Principles in C#

Audience:  

This course is designed as a follow on to the Developing Applications in C# course.  Students familiar with basic C# syntax will benefit from this course

Length: 

3-4 days 

Overview 

This course introduces the student to a powerful design pattern that helps decouple components so that more flexibility is achieved.  Specifically, the pattern known as Inversion of Control, aka Dependency Injection, is examined in this course along with the benefits to design.  Flexibility, reuse, and maintainability are goals.  We will use the Unity or Ninject framework to demonstrate this pattern..  This course is rich in hands-on opportunities (50%).
