LINQ is the best feature in C#. If you’re interested in writing more expressive code to work with collections, this course is for you. In this course, you will learn about what LINQ is and what lambda expressions are. You will learn the most common LINQ methods and some common pitfalls to avoid when using LINQ. You will also write your first methods using LINQ and use LINQ to refactor some common constructs.
