1. What is C#?

C# is a multi-paradigm programming language encompassing strong typing, imperative, declarative, functional, procedural, generic, object-oriented (class-based), and component-oriented programming disciplines. It was developed by Microsoft within its .NET initiative and later approved as a standard by Ecma (ECMA-334) and ISO (ISO/IEC 23270:2006). C# is one of the programming languages designed for the Common Language Infrastructure.

2. What is a Namespace?

Namespaces in the .NET Runtime are used to organize classes and other types into a single hierarchical structure. The proper use of namespaces will make classes easy to use and prevent collisions with classes written by other authors.
