Mastering Events and Delegates in C#

Simple event handlers that do things like make buttons and menu items perform actions, are commonly used by even novice C# programmers. The concept of delegates can seem more complicated and is often avoided by beginners for that reason. However, delegates are working behind the scenes and you are using them without realizing it every time you use events. A better understanding and more control of event handlers will come with a better understanding of delegates.

In this course, C# wizard Rod Stephens reveals the relationship between delegates and events. He shows you how delegates function, and once that is clear he takes you on a tour of the advanced ways in which you can now work with events. Prerequisites for the course include some C# experience and a computer running Visual Studio 2015.
