Intermediate Language in .NET - (BCA / B.Tech)

Intermediate Language (IL) in .NET in Hindi | Intermediate Language in Hindi:

What is Intermediate Language (IL)?

In the .NET Framework, Intermediate Language (IL) is also known as Microsoft Intermediate Language (MSIL) or just Common Intermediate Language (CIL).
It is a low-level programming language that is compiled for all .NET programs.

When we write code in any of the .NET languages (like C#, VB.NET, F#), that code is not directly understandable by the machine.
That code is first compiled into Intermediate Language (IL).

Process of Intermediate Language in Hindi | Process of Intermediate Language:

.NET's Just-In-Time (JIT) Compiler converts this IL into machine code at runtime, which can be understood by the CPU.

Steps of the IL process:

Source Code:

The programmer writes code in any of the .NET languages (like C#, VB.NET).
Compilation: This code is compiled into Intermediate Language (IL) by the .NET Compiler and is saved as a .dll or .exe file.
Execution (runtime): When this program is run, the .NET Common Language Runtime (CLR) converts the IL into machine code.

Advantages of Intermediate Language in Hindi | Advantages of Intermediate Language:

Language Interoperability: Code written in different languages under .NET (like C#, VB.NET) is compiled into the same IL. This means that all languages can work together.
Platform Independence: IL code is not platform-dependent. It can work on any platform where the .NET Framework or .NET Core is available.
Performance Optimization: The JIT Compiler optimizes the code at runtime, which results in better performance.
Security: IL code is monitored by the CLR, which makes the code more secure.

Main features of Intermediate Language:

Stack-Based Architecture: IL works on a stack-based architecture, where data is loaded into the stack and processed.
Object-Oriented: IL has all the features of object-oriented programming (OOP).
Stored in Assembly: IL code is stored as a .exe or .dll file. This is called an Assembly.
Flexibility: IL code can be easily converted to other languages.

Example of Intermediate Language:

C# code:

using System;

class Program

{

static void Main()

{

Console.WriteLine("Hello, World!");

}

IL code: When it is compiled into IL, it looks something like this:

.method public hidebysig static void Main() cil managed

{

.entrypoint

IL_0000: ldstr "Hello, World!"

IL_0005: call void [mscorlib]System.Console::WriteLine(string)

IL_000A: ret

}

ldstr means "load string".
call means to call a method.
ret means "return".

Functioning of Intermediate Language:

1. Common Language Infrastructure (CLI): The CLI is a standard of .NET, in which IL is used. It makes .NET multi-language and platform-independent.

2. Common Language Runtime (CLR): The CLR does the work of converting IL to machine code at runtime.

3. JIT Compiler: The JIT Compiler converts IL to machine code. This process is fast and optimized.

Why is Intermediate Language important?

A common basis for different languages: The .NET Framework supports many languages. IL acts as a common language for all languages.
Optimization at runtime: The JIT Compiler optimizes IL while converting it to machine code, which improves the performance of the application.
Portability: IL code can be run on any platform where the CLR is available.

Intermediate Language and the future of .NET

The use of IL is not only on the .NET Framework but also on platforms like .NET Core and now .NET 6/7. This makes .NET more flexible and powerful.
It is being used for gaming, web applications, mobile applications, and cloud-based solutions. IL is a fundamental part of all modern technologies that come with .NET.
Intermediate Language is one of the fundamental parts of .NET, which provides the facility for different languages and platforms to work together.
