Assalamu Alaikum, dear programmers, today we will talk with you about .NET Architecture.
A .NET Framework program written in any supported programming language is first translated into bytecode by the .NET Common Intermediate Language CIL, formerly Microsoft Intermediate Language, MSIL. In .NET terms, this assembly is considered an assembly. The code is then executed by the Common Language Runtime CLR virtual machine or translated by NGen.exe into executable code for a specific target processor.
Using a virtual machine (VM) is preferred because it frees developers from having to worry about hardware specifics. When using the CLR virtual machine, the built-in JIT-compiler just-in-time converts the intermediate bytecode into the machine code of the required processor. Modern technology of dynamic compilation allows to achieve a high level of performance. The CLR VM also handles basic security, memory management, and exceptions, saving the developer some of the work.
The architecture of the .NET Framework is described and developed in the Common Language Infrastructure CLI specification developed by Microsoft and approved by ISO and ECMA. CLI.NET describes data types, application structure metadata format, bytecode execution system, and more.
.NET object classes available for all supported programming languages ​​are available in the Framework Class Library FCL. FCL includes Windows Forms, ADO .NET, ASP.NET, Language Integrated Query, Windows Presentation Foundation, Windows Communication Foundation, and more. The core of FCL is called the base class library BCL.
