Describe the roles of CLR in .NET Framework.

CLR gives an environment to execute .NET applications on target machines. CLR is also a common runtime environment for all .NET code irrespective of their programming language, as the compilers of respective language in .NET Framework change every source code into a common language known as MSIL or IL (Intermediate Language).

The responsibilities of CLR are listed as follows:

    Automatic memory management
