Introduction

This course assumes that you're already familiar with the basics of C# programming (see notes on course prerequisites at the bottom of this page). The course is aimed at people who know the basics of programming in C#, but want to know what words like inheritance, delegates, interfaces and classes really mean.

Prerequisites

You should not attend this course if you are a beginner at C programming (in which case choose our two-day introduction to C# course instead). If you are already an expert on creating classes and implementing inheritance this is not the course for you either.
