The following reasons make C# a widely used professional language: It is a modern, general-purpose programming language It is object oriented. It is component oriented. It is easy to learn. It is a structured language. It produces efficient programs. It can be compiled on a variety of computer platforms. It is a part of .Net Framework.

2. C# code does not require header file.

3. C# supports number of modern features
such as-
 Automatic Garbage Collection
 Error handling features
 Modern debugging features
 Robust security features

4. In c# everything is an object. There are no
global functions, variables and constants.
It supports all three object oriented
features-
 Encapsulation
 Inheritance
 Polymorphism

5. Type safety promotes robust programming.
Example-
 All objects and arrays are initialized by 0.
 An error message will be generated if we
use uninitialized variable.
 Automatic checking of array out of bond.

6. Making new versions of software module
work with the existing applications is
known as versioning. It is achieved by the
keyword new and overwrite.

7. C# enforces the .NET common language
Specification(CLS) and therefore allows
interpolation with other .NET languages.

8. C# supports for using object models, no
matter what language is used.
