Course Description

This 2-day intensive C# Programming Essentials training course is designed to help the experienced software developer quickly come up to speed on the C# language. This course concisely covers the foundations of programming using Microsoft’s C# programming language. It starts with a brief chapter, “.NET: What You Need to Know,” which gets the student up and running in the .NET environment with a minimum of fuss.

The next two chapters cover C# language essentials and object-oriented programming in C#, followed by a discussion about how C# relates to the .NET Framework. The course then moves on to cover delegates and events. The course also includes a succinct introduction to creating GUI programs using Windows Forms. The course wraps-up with a chapter covering the new features in C#. Appendices provide a tutorial on Visual Studio as well as an overview of LINQ. The course is practical, with many example programs and a progressively developed case study.

Pre-requisites

Programming in a high-level language is required and some background in object-oriented programming is recommended.

Who is this Course For?

Software Developers who need to design and develop using C# for the .NET framework.

Further Training

A more in-depth exposure to C# and Microsoft.NET can be gained through attendance at our C# Programming Advanced training course.
