C# Master Class

So, you know C#. You've learned the syntax, learned how to write classes and interfaces, know your lists from your lambdas, and have some experience using both the C# language and the .Net framework. Perhaps you took our Beginner and Intermediate courses - or you already know what they teach. What next?

The C# Masterclass moves beyond the syntax and semantics. Its focus is on applying C#, along with selected parts of the .Net framework, to build elegant, extensible, multi-paradigm solutions to everyday problems. You'll learn how to apply classes and interfaces to achieve solid OO designs, how to work efficiently with lambda expressions, how to re-cast traditionally imperative problems as concise Linq queries, how to tame asynchrony with using the async/await keywords - and much more!
