Everything you need to master the art of LINQ in .NET
C# 3 added one of the most revolutionary features of any programming language, and that’s none other than LINQ. LINQ has been a flagship feature of C#. Data querying is a fundamental feature of any programming language, but not every language gives developers the tools to do it in an elegant way that reads naturally and is extremely powerful. Even though most developers will get introduced to LINQ early in their C# journey, only a few know how to use it effectively and get the most out of it with the least amount of code. With heavy Microsoft investment, LINQ is improving in every .NET version with better performance and adding new features. In this course, Hannes Lowette will teach you everything there is to know about LINQ and equip you with the knowledge to tackle and querying tasks, whether big or small.
