.NET Framework, .NET Core, .NET Native, DNX, Core CLR, CIL, PCL - simple explain?

Question

Today's .NET world looks too complex. Could somebody give a short explain of these terms?

There is some info in this thread, but it not discovers a complete picture.

Answer 1

• NET Framework: full blown Framework for running managed solutions in the Windows Ecosystem
• NET Core: reduced set of NET Framework, that is cross-platform and supports applications for various OSes and CPUs
• NET Native: Framework that converts C# to C++ like code and is used for developing Windows 10 universal apps
• DNX: NET Execution Environment - contains the code required to bootstrap and run an application, including the compilation system, SDK tools, and the native CLR hosts (basically cross-platform developing mechanisms)
• Core CLR: .NET Core runtime: framework supporting the NET Core
• CIL: intermediate representation of the C# code (similar to Java bytecode) that will be further translated into assembly code by the JIT compiler
• PCL: Portable Class Library - class library for Universal apps

Answer 2

.NET framework- is basically a programming infrastructure created by Microsoft for building, deploying, and running applications and services that use .NET technologies, such as desktop applications and Web services.
.NET core- is the NET Core is the small optimized runtime that is the basis of ASP.NET Core 5.
.NET native- is a precompilation technology for building Universal Windows apps in Visual- Studio 2015
DNX- Dot Net Execution environment is a new .NET SDK that is designed to allow development and execution across multiple platforms.
core CLR- is basically a .NET core runtime which includes the garbage collector .
CIL- C Intermediate Language is the lowest-level human-readable programming language is a simplified transformation of C used for further analysis
PCL- Portable Class Libraries enables .NET developers to write and build managed assemblies that work on more than one .NET Framework platform
