C# is an object-oriented programming developed by Microsoft that uses the .Net Framework. It utilizes the Common Language Interface (CLI) that describes the executable code as well as the runtime environment. C# can be used for various applications such as web applications, distributed applications, database applications, window applications etc.

For greater understanding of this tutorial, a basic knowledge of object-oriented languages such as C++, Java etc. would be beneficial.
