What is "Common Language Runtime" (CLR)?

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.
The CLR is the execution engine for .NET Framework applications. It provides a number of services, including:
• Code management (loading and execution)
• Application memory isolation
• Verification of type safety
• Conversion of IL to native code.
• Access to metadata (enhanced type information)
• Managing memory for managed objects
• Enforcement of code access security
• Exception handling, including cross-language exceptions
• Interoperation between managed code, COM objects, and pre-existing DLL's (unmanaged code and data)
• Automation of object layout
• Support for developer services (profiling, debugging, and so on).

Common Language Run-time (CLR):The most important part of the .NET Framework is the .Net Common Language Run-time (CLR) also called .Net Run-time in short. It is a framework layer that resides above the Operating System and handles/manages the execution of the .NET applications. Our .Net programs don’t directly communicate with the Operating System but through CLR
