Introduction to C# Programming for the Microsoft .NET Platform

Course 2124 : 5 days; Instructor-Led

The goal of this course is to provide students with the knowledge and skills needed to develop C# applications for the Microsoft® .NET Platform. The course focuses on C# program structure, language syntax, and implementation details.

C# was created to be the programming language best suited for writing enterprise applications for .NET. C# combines the high productivity of Microsoft Visual Basic® with the raw power of C++. It is a simple, object-oriented, and type-safe programming language that is based on the C and C++ family of languages.
