What is CLR?

CLR main part of .Net technology.It is used to integrate all languages on .Net platform.CLR provide facility of conversion languages from one to another.

CLR Common Language Run time and it forms the heart of .NET. All languages have autonomy and responsibility to ensure that the run time code to run the program. CLR has been described as execution engine of .NET. This CLR that manages the program and provides an environment for programs.

Common Language Runtime (CLR)

The CLR is described as the "execution engine" of .NET. It provides the environment within which the programs run. It's this CLR that manages the execution of programs and provides core services, such as code compilation, memory allocation, thread management, and garbage collection. Through the Common Type System (CTS), it enforces strict type safety, and it ensures that the code is executed in a safe environment by enforcing code access security. The software version of .NET is actually the CLR version.

When it is worked CLR:

When the .NET program is compiled, the output of the compiler is not an executable file but a file that contains a special type of code called the Microsoft Intermediate Language (MSIL), which is a low-level set of instructions understood by the common language run time. This MSIL defines a set of portable instructions that are independent of any specific CPU. It's the job of the CLR to translate this Intermediate code into a executable code when the program is executed making the program to run in any environment for which the CLR is implemented. And that's how the .NET Framework achieves Portability. This MSIL is turned into executable code using a JIT (Just In Time) complier. The process goes like this, when .NET programs are executed, the CLR activates the JIT complier. The JIT complier converts MSIL into native code on a demand basis as each part of the program is needed. Thus the program executes as a native code even though it is compiled into MSIL making the program to run as fast as it would if it is compiled to native code but achieves the portability benefits of MSIL.

It provides execution and compilation services. In the CLR manages the form of bytecode called Common intermediate language. In short it is called. net runtime.

CLR be held for the common language runtime, and form the heart. NET. All language runtime and execution is to oversee the implementation of the program code. write code using CLR languages such as C # or VB.NET. Compilation. NET converts the CIL code for the sample code. Running the CLR compiler Just-in-time converts the CIL code from the code of the operating system.

Developers using the CLR to write code in a language such as C # or VB.Net. At compile time, compiler. NET converts the code as in the CIL code. At runtime, the CLR compiler Just-in-time converts the CIL code into code native to the operating system. Otherwise, the CIL code can be compiled to native code in a separate step before execution.

CLR is the abbreviation of the common language runtime is the most important part of . NET framework. All language has its run-time and run-time responsibility to take care of code execut.

Thanks for sharing.It is new for me because I never use .NET.

CLR is Common Language Runtime and is the most vital component of the structure. NET. All languages have runtime and it is the responsibility of the runtime to address the code execution.
