Object Oriented Programming with C# (2018)

Course details

Learn how to use object-oriented programming (OOP) principles in C# to help simplify some of your more complex work. In this course, Anton Delsink explores the many features of C# that support object-oriented programming, including abstract classes, interfaces, and generic types. To help lend a real-world context to these concepts, Anton demonstrates how to use these features by example as he examines existing code and writes some new code. Throughout the course, he covers a wide range of scenarios—including examples from .NET, Windows UI, the web, and even board games—and discusses whether or not he adhered to OOP principles in different instances.
