Intermediate C#

Using C# 6.0 effectively means going beyond the object oriented features of the language. Effective C# developers make good use of generics, LINQ (Language Integrated Query) and lambda expressions. They use enumerations, nullable types, initializers and extension methods to write cleaner code that is easier to refactor. This course steadily takes developers with a working knowledge of the object oriented features at the core of the C# language to the next level.
