What is CLR?

CLR is the short form Common Language Runtime (CLR). It is a .NET framework of Microsoft that enables working of programs bearing various supported languages.

CLR is a component of Microsoft’s .NET framework. But it won’t allow a programmer to create a new language. Instead, CLR assists developers and programmers to integrate different texts or communication media into .NET framework.

Necessary Points and features of CLR:

• It converts the source code into a form of bytecode. This bycode has been termed as the Common Intermediate Language (CIL).
•  It manages the conversion or execution of the CIL code at the run time.
• The programmers use such languages as C# or VB.Net. These are codes written in a supported .NET programming language.  They are subsequently changed into CIL code.

Pros of CLR:

• It enables or permits easy use of different supported languages to reach the target or common goal.
• Programmers find it versatile and flexible to select their own programming language. But it must be supported by the .NET framework.
• NET finds CLR handy as the management and execution of all supported languages can be done. This can be done by changing or transforming the languages first to bytecode and then into the native code for the chosen platform. 

Cons of CLR:

• CLR can be used only on .NET supported framework.
• CLR may not be suitable for dynamically typed languages.
• Transfer or migration of applications to other formats from .Net will be difficult.

Conclusion:

In short, the function of CLR is to change the CIL code in a language that can be easily realized or comprehended by the operating system in which the programmers are working in the run time. It offers an option for programmers set on working on new language implementations.
