Has own class libraries. System is the main namespace and all other namespaces are subsets of this.

It has CLR(Common language runtime, Common type system, common language specification)

All the types are part of CTS and Object is the base class for all the types.

All the code compiled into an intermediate language by the .Net language compiler, which is nothing but an assembly.

During runtime, JIT of CLR picks the IL code and converts into PE machine code and from there it processes the request.
