Что может означть слово "runtime" в .NET
В общем runtime — это набор чего-то (компонент, библиотек, инструментов), который необходим для работы определенного типа приложения.
Часто под runtime подразумевается механизм выполнения (среда выполнения) .NET приложения, например: CLR, .NET Native или Mono runtime. Этот механизм овечает за управление памятью, загрузку сборок, выполнение, генерацию и компиляцию JIT кода.
Также рантаймом может называться набор компонент, который необходим для работы приложения, например, ASP.NET runtime или .NET runtime (Это две разных среды выполнения, т.к. они опираются на разный набор компонент, в ASP.NET Core runtime входят библиотеки, которые расширяют набор библиотек .NET runtime).
Слово «runtime» может использоваться в определениях, например, Runtime Identifier (RID) — здесь runtime — это ОС и архитектура CPU, на которой запускается .NET приложение, например, linux-64.
Рантаймом тажке называют определенную релизацию .NET. Вариантов Реализаций .NET уже несколько, например: .NET Framework, .NET 5 (.NET Core), UWP, Mono.
What's the difference between SDK and Runtime in .NET Core?
I’ve read many articles, including this one, yet I can’t still figure out what’s the difference, and they have not explained it either in simple terms or at all.
Can someone please clarify what’s the difference between .NET SDK and .NET Runtime?
Update: Using comparisons would be very appreciated. Analogy alongside simple English is highly educational.

According to the .Net Core Guide, .NET Core is composed of the following items
- A .NET runtime, which provides a type system, assembly loading, a garbage collector, native interop and other basic services.
- A set of framework libraries, which provide primitive data types, app composition types and fundamental utilities.
- A set of SDK tools and language compilers that enable the base developer experience, available in the .NET Core SDK.
- The ‘dotnet’ app host, which is used to launch .NET Core apps. It selects the runtime and hosts the runtime, provides an assembly loading policy and launches the app. The same host is also used to launch SDK tools in much the same way.
The SDK is all of the stuff that is needed/makes developing a .NET Core application easier, such as the CLI and a compiler.
The runtime is the «virtual machine» that hosts/runs the application and abstracts all the interaction with the base operating system.
Only the latter is required to run the application, but the former is needed to develop the application.
Runtime: to run apps
SDK (Runtime + Tooling): to build and run apps
I’m not inventing anything here. Just copy-pasting the definitions from https://dotnet.microsoft.com/download
The software development kit (SDK) includes everything you need to build and run .NET Core applications, using command-line tools and any editor (like Visual Studio).
The runtime includes everything you need to run .NET Core applications. The runtime is also included in the SDK.
Only the .NET Core Runtime is required to run an application and provides information about the install.
To develop, build and publish an application will require an SDK.
dotnet.exe installs with a runtime install, but it only provides core features to provide info to run an application and provide info about the install: dotnet mydll.dll and dotnet —info . To build, publish or do anything else you need to install the SDK.
Running the following command will provide information about the install:
If the command fails it means you do not have the .NET Core runtime installed or available in the system’s PATH.
Below is a sample output of the command.
- The installed SDK version
- The active runtime version that’s running this dotnet command
- A list of all installed runtimes and SDKs
Installing an SDK also installs the runtime.
macOS homebrew specific
Installing the homebrew-cask dotnet will conflict with the dotnet-sdk, so to get both the runtime, and the sdk install dotnet-sdk
In short, the runtime will allow your OS to run compiled C-Sharp, C# programs, and the sdk will allow you to compile programs written in C-Sharp, C#.
It’s important to understand that you can have multiple runtimes and multiple SDKs installed and each project can use a different one. The runtime is determined by your project’s runtime specifier in the .csproj file:
.NET Runtime and its Components��������
It is pertinent to note that microsoft .NET runtime is a free open source platform for developing apps. It is similar to that of .NET framework and a developer can work on web applications and services for any platform from the windows device. These windows devices include Mac,linux and mobile operating systems. It is of paramount importance that .NET runtime can help developers implement deployable microservices for people having docker containers. .Net is also a library of shared code for developers. That shared code allows them to insert it to perform functions without writing the code from scratch. If you’re not a software developer, all you care about is that it works.
The two major components of .NET Framework are the Common Language Runtime(.NET Runtime) and the .NET Framework Class Library. The Common Language Runtime (CLR) is the execution engine that handles running applications. It provides services like thread management, garbage collection, type-safety, exception handling, and more. The Class Library provides a set of APIs and types for common functionality. It provides types for strings, dates, numbers, etc. The Class Library includes APIs for reading and writing files, connecting to databases, drawing, and more. .NET applications are written in the C#, F#, or Visual Basic programming language. Code is compiled into a language-agnostic Common Intermediate Language (CIL). Compiled code is stored in assemblies-files with a .dll or .exe file extension.
When an app runs, the CLR takes the assembly and uses a just-in-time compiler (JIT) to turn it into machine code that can execute on the specific architecture of the computer it is running on.
Importance of .NET Runtime✌
Free App Development Platform��
The dotnet runtime is a great tools for gamers to develop games for console, 2 or 3D graphics. It also supports for internet of things. Starting with Microsoft .Net 3.5, all versions released are supposed to be backward compatible. For example, if you needed .Net version 4.6.1 and you installed 5.0, it should work
Language support��
While many developers like using C#, Microsoft NET Runtime also gives you the options of F# and Visual Basic. Each one has its own advantages, and it depends on the developer’s purpose and preference. You can change the language in the settings before your start your project.
Knowledge base��
Microsoft offers a massive knowledge base for their NET Runtime software. There are online videos you can use that will show you how to use specific functions and commands. You’ll also find valuable advice from some of the contributors, guiding you towards better app development.
Cloud services
If you’re building apps for the cloud, Microsoft NET Runtime works in conjunction with Azure due to optimal compatibility. It contains templates to make your development go faster, while it also lets you migrate any of your previous projects over into its environment. Of course, you can also try to integrate it with a different environment of your choice.
Enhance your app development
Microsoft NET Runtime attempts to provide you with the best solution for offline, online and cloud app development for several platforms. While there are tutorials to guide you as a beginners, experts should have no problem using this system.
Many developers starting out with .NET might be perturbed about which version to download. The Microsoft windows desktop Runtime is what end users needs to download. Actually, we can call this End-user runtimes or redistributable package. Over the years, the name has changed to just Runtime is versions 5.0. This clearly appears in apps and features. This appearance in features and apps are called Microsoft Windows Desktop Runtime. .NET runtime have built-in algorithms, predictive models and speech processing speeding software development. Creating apps for Several Platform While this version of Microsoft NET Runtime is designed to work on Windows, you aren’t limited to the platform that apps and games are developed for. Whether you’re aiming for console, mobile phones, or computers with Windows, Linux or Mac, you can create programs as long as you have the Software Development Kit (SDK).
The software development kit (SDK) includes everything you need to build and run .NET Core applications, using command-line tools and any editor (like Visual Studio).
The runtime includes everything you need to run .NET Core applications. The runtime is also included in the SDK. The first thing to know is that the Runtime and SDK are separate things.
The runtime is (as it sounds) the bit you’ll need to run a .NET program on your machine. Windows ships with a version of .NET which is generally kept up to date via OS updates.
The SDK is the bit you need if you want to develop applications using .NET.
There are several production-ready versions of the runtime and SDK.
Choose Your Runtime��♂️
If you’re interested in knowing which version(s) of .NET are officially supported by Microsoft, check out the Microsoft support policy Microsoft support policy which gives you that information.
The CLI is very important in .NET because whenever we write the code, it is converted to intermediate language at first compile. This intermediate language is running on the CLR. So the whole program is monitored by the CLR.
Just-in-time(JIT) Compiler
When an app runs, the CLR takes the assembly and uses a just-in-time compiler (JIT) to turn it into machine code that can execute on the specific architecture of the computer it is running on.
Code Manager
As the name signifies,it manages the code during execution and allocates memory to objects.
Type Checker
This checks datatype of variables.
Debug Engine
The debug engine is used to find and remove bugs from the program.
Class Loader
This loads data in runtime
Exception Manager
The exception manager manages exception in both managed(intermediate language like .NET and Java) and unmanaged code(C and VB).
Thread Support
The CLR support multi-threading.
Security Checker
This helps to restrict access to the system resources for example the intermediate languages or managed code should have a restricted access.
Garbage Collector
The garbage collector periodically checks the heap memory for unused objects.
Summary��
In Summary, any program written in .Net needs to have the .Net runtime installed. Windows 10 comes with .Net installed should update it as needed, which isn’t very often. Often, when you don’t have the correct version of .Net installed, it will automatically update you ��.
