Advanced C#

This course will help you become a more efficient C# developer. We will look at generics, LINQ (Language Integrated Query) and lambda expressions. We use enumerations, nullable types, initializers and extension methods to write clean and maintainable code. This course is for developers with a working knowledge of the object oriented features at the core of the C# language, and will take you to the next level. We work with the latest version of C# and also get a glimpse of .NET Core.
