CLR(Common Language Runtime) managed
CTS(Common Type System) Implement variable compatible type of COM and define the way of use user-defined type to extend types. Support all possible data type and programming structure, define how to express the format of .NET metadata.

CLS(Common Language Specification)Define sub-set of common types and programming structure which is supported by all .NET language.
BCL(Basic Library)
Encapsulation kinds of basic types(Thread, File I/O, Web API, GUI desktop API, Data access, Security, Remote Handle API)
CIL(Common Intermediate Language)
C# compiler generate the CIL.
CIL---JIT compiler--->CPU instruction.
Using ildasm.exe in VS command to see the CIL code.(Ctrl+M: see all MetaInfo)
BTW, Reflector can see all the managed code.
