Code Refactoring for .NET

We look at the approaches and methods for improving source code readability in C#. You値l practice refactoring of small programs, focusing on various aspects of improving the existing code.
Code: DEV-006_NET
Duration: 24 hours


Have you ever encountered source code is difficult to read? Where you spend a lot of time trying to understand what the developer wanted to express in that particular code fragment.

In this training we値l show you how to not become that developer. You will learn about code smells, why and where they appear, and what techniques are used to remove them. We値l start from simple problems in a single function and end with problems of communication between classes. We will also discuss what should and what should not be done to make your code easy to read.
