Introduction to C#

In simple words, C# (pronounced See-Sharp) is a programming language that is developed by Microsoft. C# is approved by International Standards Organization (ISO) and European Computer Manufacturers Association (ECMA).

This is the definition on the official website (https://docs.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/index):

Language C# is designed to adhere to Common Language Infrastructure (CLI), which we discussed on day one.

C# is the most popular professional language because of the following reasons:

• It is an object-oriented language
• It is component-oriented
• It is a structured language
• The main part that makes it the most popular: this is a part of the .NET Framework
• It has a unified type system, which means all types of language C# inherits from a single type object (this is also known as the mother type)
• It was constructed with a robust durable application such as Garbage collection (discussed on day one)
• It has the ability to handle unknown issues within a program, which is known as exceptional handling (we will discuss exception handling on day four)
• Robust support of reflection, which enables dynamic programming (we will discuss reflection on day four)
