Hi CLR is Common Language Runtime is the runtime that converts a MSIL code into the host machine language code. It is the execution engine for .NET Framework applications. It provides a number of service including; Code management (loading and execution) Memory Management Thread Management Conversion of IL to native code. Access to metadata (enhanced type information) Managing memory for managed objects (Garbage collection) Enforcement of code access security (Security Management) Exception handling, including cross-language exceptions Interoperation btw managed code, COM objects, and pre-existing DLL's (unmana.ed code and data) Support for developer services (profiling, debugging, and so on). Type safety.

Hi, The Common Language Runtime ( CLR ), the virtual machine component of Microsoft's . NET framework, manages the execution of . NET programs. A process known as just-in-time compilation converts compiled code into machine instructions which the computer's CPU then executes.
