Although C# is considered an imperative (procedural) language, there are techniques we can borrow from a declarative (functional) language, such as F#, that will allow us to write more robust, testable and maintainable code. The recent additions to the C# language make the transition from writing C# code using a procedural approach to a functional approach even easier.

In this talk we will discuss applying functional techniques to C# code and the advantages of thinking “functional” instead of procedural. We will transform examples of C# written in a traditional imperative style to a functional style incorporating some of the newer C# language features. In addition, although not a recent addition to C#, we will also demystify the scary looking Action and Func to demonstrate how powerful these delegate wrappers can be used to write flexible and reusable code.

Steve is excited about the latest F# and C# language features allowing developers to write cleaner, maintainable, and more robust code than ever before.
