Course Overview

A deep understanding of design patterns and the ability to apply them to relevant design challenges is key to writing good code. They ensure the code is easy to understand and maintain, can be extended in the face of evolving requirements, and can be reused as needed. This course will help you learn design patterns by providing context for using each design pattern and mapping it to common real-world problems that developers can relate to. It also provides hands-on code examples in C# to help apply the lea...Show More
