C# Master Class
Learn how to take advantage of what C# and .Net offer. We take a range of real-world problems, and uses modern C# and .NET features...
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 advanced C# 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 tame asynchrony with using the async/await keywords - and much more!
The course is up-to-date with the latest C# 9 and and most exercises are done targeting the latest version of .NET 5. Even if you don't use .NET 5 or .NET Core today, this course is still relevant and most of the concepts taught in this course works on both .NET 5, .NET Core and .NET Framework.
The course consists of plenty of hands on exercises where you get to apply the things you learn.
Target audience
This course is aimed at those who have a working knowledge of C# and want to learn to apply the language in a more powerful way, taking advantage of all it has to offer.
Prerequisites
Participants should be comfortable with programming in C#. Some previous experience with generics, lambda expressions, and Linq queries is strongly suggested.
