Welcome to the "LINQ Tutorial: Master the Key C# Library", the only course you need to become fluent in using library essential for every C# programmer.

No matter what application you work on or ever will work on - you will always need to manipulate collections. Whether it's ordering, filtering, or transforming collections, or anything else - LINQ is the tool for the job. As a core part of .NET, it's a library that every C# programmer must know. LINQ provides the ability to not only query the collections stored in application memory, but also remote data sources, like databases or XML files.

Check out the free video about one of the most commonly used methods from LINQ - the Where method.

This course is practice-oriented. After each lecture, you will solve two coding exercises and one refactoring challenge, where you will transform an awkward code into an elegant, short, and clean code using LINQ. Even if you won't be able to solve the exercise right off the bat, don't worry - an article with a detailed explanation of the solution is provided for each exercise.

This course is for everyone with basic knowledge of C#. Every topic will be explained in detail. In the introduction section, you will learn all you need to continue, like what lambda expressions are or what IEnumerable is.

If you already know some LINQ, this course will help you start using it like a pro, as well as understand how it works under the hood.

By solving 64 coding exercises and 32 refactoring challenges, you will gain practical knowledge of LINQ and become a better programmer. You will start "thinking in LINQ" and using this amazing library will become a natural thing to you.

Don't forget that LINQ knowledge is expected by basically every employer, and it's extremely often verified during interviews. After taking this course, you will gain confidence in discussing the topic of LINQ.

LINQ has two ways of writing queries - the method syntax and the query syntax. We will learn both of them.

You'll be able to access all examples from videos, as well as all coding exercises and refactoring challenges, including solutions, in the Git repository included in this course.
