For using these technologies, you must be skilled on query technics. LINQ ensures you to create queries efficiently. • In this course you will learn querying by LINQ(Language Integrated Query) properly. We will study totally 2 main chapters during the course. These are; Introduction to LINQ and Query Object Collections. • This tutorial appeals to .NET developers by using C# .NET language. So, before this course you must learn C#.NET basics and Object Oriented Programming principles. • Main purpose of this tutorial is making the best beginning to Language Integrated Query. • If you follow lecture order and practice whole examples, at the end of tutorial you can easily create queries that all on your need. • Practice homeworks and answer quiz questions. These tasks are given you to improve your querying skills. • Have a nice learn ! • Yours sincerely... • What are the requirements? • Download and setup Visual Studio 2013 Express Edition.
