When an application is first launched, the .NET Framework compiles the CIL code into executable code using its just-in-time compiler, and caches the executable program into the .NET Native Image Cache..
Support for multiple programming languages.
The key languages for .
NET are C#, Visual Basic and F#.
Additionally, it can work with other languages developed by Microsoft, such as C++ and IronPython (11 languages in total), and can support 50 languages created by other entities..
C# is a compiled language.
To run an application, normally a developer compiles C# source code into intermediate language (IL).
This way, it can be executed across different target systems.
During the execution, IL code is compiled further into machine code of the current target system and CPU executes it on the go..
In .
NET, programs are not compiled into executable files; they are compiled into Microsoft Intermediate Language (MSIL) files, which the CLR then executes.
The MSIL (often shortened to IL) files that C# produces are identical to the IL files that other .
NET languages produce; the platform is language-agnostic..
The core mission of the .
NET Compiler Platform ("Roslyn") is opening up the C# and Visual Basic compilers and allowing tools and developers to share in the rich information compilers have about programs.
Code analysis tools improve code quality, and code generators aid in application construction.Mar 9, 2023.
Microsoft's implementation of C# is also heavily integrated with the .
NET framework, so it's understandable that these two concepts would be confused, but they are different things.
C# is a programming language and .
NET is the framework and runtime that C# programs are built with and run on..
NET Framework's Common Language Infrastructure (CLI) implementation.
As an implementation of CLI's Virtual Execution System (VES), CoreCLR is a complete runtime and virtual machine for managed execution of CLI programs and includes a just-in-time compiler called RyuJIT. .
NET Core also contains CoreRT, the ..
Roslyn, the .
NET Compiler Platform, empowers the C# compiler on .
NET Core and allows developers to leverage the rich code analysis APIs to perform code generation, analysis and compilation..
.NET Compiler Platform SDK.
The .
NET Compiler Platform (“Roslyn”) provides open-source C# and Visual Basic compilers with rich code analysis APIs.
You can build code analysis tools with the same APIs that Microsoft is using to implement Visual Studio..
About Compiling
The compiler takes the text that you've written and will convert it to machine code (in the case of languages such as C++) or an intermediary language that can be executed by a Just In Time Compiler (in the case of languages such as C# and Java)..
First, locate the C# compiler on your computer. (You can use your computer's search facility: press Start in the lower left corner, press Search, then within the Search window, select ``Search all files'' and then type a search for csc.exe.) This folder is the ``path'' to the compiler..
C# Compiler for Windows :
Visual Studio Express 2015 for Windows Desktop, which supports Visual C# as well as other languages, it's available free download from Microsoft ( Download Latest Version From Here )..
Developers like to use .
NET because it includes many tools that make their work easier.
For example, using the Visual Studio suite, developers can write code faster, collaborate efficiently, and test and fix their code efficiently.
The ability to reuse code between implementations reduces the cost of development..
The JIT Compiler
It fits the actual set of instructions to the specific machine on which it is executed, using machine-agnostic bytecode.
Since using a JIT compiler delays application startup times a bit (compared to statically compiled code), VM runtime vendors have taken some approaches toward optimizing it..
Many teams have coding standards that are enforced through code reviewswith other team members.
Analyzers and code fixes can make this processmuch more efficient.
Code reviews happen when a developer shares their workwith others on the team.
The developer will have invested all the time needed tocomplete a new feature before getting any comments.

The .NET Compiler Platform SDK dramatically lowers the barrierto entry for creating code focused tools and applications.
It creates manyopportunities for innovation in areas such as meta-programming, codegeneration and transformation, interactive use of the C# and Visual Basic languages,and embedding of C# and Visual Basic in domain-specific langua.
The .NET developer community has discovered, through experience, patterns thatwork well and patterns that are best avoided.
Several community membershave created analyzers that enforce those recommended patterns.
As we learnmore, there is always room for new ideas.
These analyzers can be uploaded to theVisual Studio Marketplaceand downloadedby deve.
There is a wealth of libraries available for .NET developers on NuGet.Some of these come from Microsoft, some from third-party companies, andothers from community members and volunteers.
These libraries get moreadoption and higher reviews when developers can succeed with thoselibraries.
In addition to providing documentation, you can provide analyz.
The user friendly C# online compiler that allows you to write C# code and run it online.
The C# text editor also supports taking input from the user and standard libraries.
It uses ,the mono compiler to compile code.
Instead of being opaque source-code-in and object-code-out translators, through Roslyn, compilers become platforms:
With one download, the .NET Coding Pack gives you everything you need to get started coding with C#.
The pack includes ,the VS Code editor, the .NET SDK, Interactive Notebooks, and more! Find official images for .NET and ASP.NET Core on the Microsoft Artifact Registry.
Build web apps and services for macOS, Windows, Linux, and Docker.
The .NET Compiler Platform SDK enables you to build analyzers and code fixes that find and correct coding mistakes.
Analyzers understand the syntax (structure of code) and semantics to detect practices that should be corrected.
Code fixes provide one or more suggested fixes for addressing coding mistakes found by analyzers or compiler diagnostics.
