Delegates are waiting to make our code more flexible and extensible. We'll take a look at what delegates are and dispel the mystery of the built-in Func and Action delegate types. Jumping into code, we'll use them to make our classes more flexible and even use multi-casting to kick off a series of operations with a single call. Along the way, we'll see that lambda expressions can add readability to our code (yes, I actually said that). And this is a great jumping off point for heading into LINQ, parallel programming, and functional programming.

You will learn:

• Understanding what delegates are
• Using delegates for extensibility
• Getting a handle on Func, Action, and lambda expressions
