CLR - Common Runtime Language

What is CLR ?

Common runtime language is the heart of .net framework, it does 4 primary task

• Garbage Collection : It is the feature of CLR which cleans unused managed objects and reclaims it.
• CAS ( Code access security ) : It is a part of .net security which determines what kind of right does a code has.
• CV ( Code verification )  : verifies the code
• IL to native language translation : we do not know on what kind of environment will .net code run on.we do not know what will be the operating system, CPU configuration, machine configuration, security configuration,, etc. so IL code is half compiled and at runtime this code is compiled to handle machine specific using environment properties.
