Essential C# Programming Course

C# is a simple, modern, object-oriented, and type-safe programming language. C# has evolved form the C family of languages and has a syntax very similar to C, C++, and also Java.

This course is aimed at people requiring a comprehensive introduction/intermediate knowledge of the key features of the C# language.

Basic background in programming and knowledge of programming principals as covered by PTR's Fundamentals of Computer Programming using Java Course.
