The .NET Framework Class Library (FCL), also known as Base Class Library, which includes a rich set of class libraries that can use for developing appliications.
The Common Type System provides every language running on the .NET platform with a base set of data types. The Common Type System grouped as (i) Value type and (ii) Reference Type.
The Common Language System provides a set of features that different languages have in common such as languages VB .NET, C# .NET, C++ .NET, F# .NET. The CLS is a subset of the Common Type System (CTS).
