Video Description
Get a new perspective on C# code using the Functional Programming approach. Write better C# code with practical examples
About This Video
- This course focuses on the functional paradigm of C#, which will give you a whole new angle on coding with C#
- Discover everything you need to know about Functional Programming, and learn how to use it in your C# code today.
- Use Functional Programming alongside existing OOP techniques so you can get the best of both worlds and develop clean, robust code
In Detail
When C# programs get more complex, they become hard to understand, and as a result are much harder to maintain. We suggest a few approaches from Functional Programming to resolve this and make the code readable, reusable, testable and structured.
This course will present some basic Functional Programming ideas and suggest how to make use of the functional features of C# in your everyday work. As C# is deeply object-oriented by design, we'll concentrate on the bits of Functional Programming that are easily applicable to it—such as LINQ, pure functions, and dot-chaining (aka composability). We won't explore functional terms such as monads and functors in too much detail; rather we provide examples of real C# using functional features. You'll improve the maintainability and testability of your application and gain the confidence to start a new project with Functional Programming paradigms.
