Introduction to Common Language Runtime


Common Language Run-time: - Introduction
CLR is .NET equivalent of Java Virtual Machine (JVM). It is the runtime that converts a MSIL code into the host machine language code, which is then executed appropriately. CLR is similar to JVM except JVM interprets .Class file into BYTECODE where CLR compile MSIL into machine native code.

CLR is a language-neutral development & execution environment that provides services to help "manage" application execution. The common language runtime manages memory, thread execution, code execution, code safety verification, compilation, and other system services.

The Common Type System is a component of the CLR that ensures that all .NET applications use the same basic data types regardless of what programming languages were used to develop the applications.


The CLR defines the Common Type System (CTS), which is a standard type system used by all .Net languages. That means all .NET programming languages uses the same representation for common Data Types, so Common Language Runtime (CLR) is a language-independent runtime environment. The Common Language Runtime (CLR) environment is also referred to as a managed environment, because during the execution of a program it also controls the interaction with the Operating System.

Component of CLR: - Introduction The Common Language Runtime (CLR) is an Execution Environment. It works as a layer between Operating Systems and the applications written in .Net. The main function of Common Language Runtime (CLR) is to convert the Managed Code into native code and then execute the Program. The CLR has the following components 1.        Common Type System 2.        Common Language Specification 3.        Microsoft Intermediate Language 4.        Garbage Collector 5.        Code Manager 6.        JIT Compiler - Introduction Common Type System: - Introduction A fundamental part of the .NET Framework's Common Language Runtime is the CTS. The CTS defines a common set of types that can be used with many different languages. Common Type System (CTS) describes a set ...

Visual studio .Net IDE: - Introduction To develop applications in Visual Studio.Net, we use a special editor called the Integrated Development Environment (IDE).The IDE allow the user to design the applications, write the action code as well as manage the files of project. An IDE help the programmer in his tasks by provides auto-formatting of the source code, highlighting of the important keywords, etc. The IDE has smart editor, compiler and some predefined tools. These tools are used for testing the project, creating the setup and creating the help files etc. Components of  IDE: - Introduction The following are the basic components of IDE New Project Dialog Box Toolbox Window Solution Explorer Server Explorer Property Window Form Design Window Code Window
