Namespace Within The Net Framework Class Library
This naming scheme makes it easy for library developers extending .NET to create hierarchical groups of types and name them in a consistent, informative manner. It also allows types to be unambiguously identified by their full name (that is, by their namespace and type name), which prevents type name collisions. Library developers are expected to use the following convention when creating names for their namespaces:

The use of naming patterns to group related types into namespaces is a useful way to build and document class libraries. However, this naming scheme has no effect on visibility, member access, inheritance, security, or binding. A namespace can be partitioned across multiple assemblies and a single assembly can contain types from multiple namespaces. The assembly provides the formal structure for versioning, deployment, security, loading, and visibility in the common language runtime.
The System namespace is the root namespace for fundamental types in .NET. This namespace includes classes that represent the base data types used by all applications, for example, Object (the root of the inheritance hierarchy), Byte, Char, Array, Int32, and String. Many of these types correspond to the primitive data types that your programming language uses. When you write code using .NET types, you can use your language's corresponding keyword when a .NET base data type is expected.
In addition to the base data types, the System namespace contains over 100 classes, ranging from classes that handle exceptions to classes that deal with core runtime concepts, such as application domains and the garbage collector. The System namespace also contains many second-level namespaces.
The Framework Class Library or FCL provides the system functionality in the .NET Framework as it has various classes, data types, interfaces, etc. to perform multiple functions and build different types of applications such as desktop applications, web applications, mobile applications, etc. The Framework Class Library is integrated with the Common Language Runtime (CLR) of the .NET framework and is used by all the .NET languages such as C#, F#, Visual Basic .NET, etc.
The functionality of the Framework Class Library can be broadly divided into three categories i.e utility features written in .NET, wrappers around the OS functionality and frameworks. These categories are not rigidly defined and there are many classes that may fit into more tha
