Introduction to CSharp Language:

• C Sharp ( C#):

• 1 -> object oriented programming language
• 2 -> developed by miocrosoft
• 3 -> develop for .net framework
• 4 -> C/C++,Java,Vb
• 5 -> RAD(Rapid application development)

• .Net Framework:

Infrastructure/platform that provides tools & technology to use different languages to make different types of software's

• Components:

There component are:
CLR(common language runtime)
Class liabrary(a huge group of classes)

• CLR:

Means it converts managed code into native code


source code -> .net compiler -> MSIL(Microsoft Intermediate Lang) -> CLR -> Native code(Output)
                                                      Metadata                                JIT
                                                 (managed code)

• Library:

Namespace -> Group of classes with similar close properties & function.



Main namespace ->System

Before we starting  csharp language we must know about that syantax - > static void Main(string[] args)
above we will discuss basic concept step by step now we are going to know about static void Main(string[] args) what is this?

Static: Means it is made static so that we call  it without creating an object in other words run the main function with out creating an object.

Void: Means don't return any value void is a return type of function for e.g void (int abc)
where void is return type int is data type and abc is alphabet means its name.

String args[]: is the way of input at startup of the application string[] args or String args[] both are same

static void Main(string[] args)

static                 ->               class method, no need to make object to use

void                   ->              return type nothing


string[] args        ->              arguments


i think you understand this syntax static void Main(string[] args) also known as idioms in cSharp
