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.
