For a general introduction to .NET Framework for both users and developers, see Getting Started. For information about deploying .NET Framework with your app, see the deployment guide. To read about the architecture and key features of .NET Framework, see the overview.
Installation choices
Install a developer targeting pack to develop against the most recent version of .NET Framework in Visual Studio or another development environment, or download the .NET Framework redistributable for distribution with your app or control.
To install the .NET Framework Developer Pack or Targeting Pack
A targeting pack lets your app target a specific version of .NET Framework when developing in Visual Studio and some other development environments. A developer pack includes a specific version of .NET Framework and its accompanying SDK along with its corresponding targeting pack.
The developer pack for .NET Framework 4.5.1 or 4.5.2, the targeting pack for .NET Framework 4.6, and the developer pack for .NET Framework 4.6.1, 4.6.2, 4.7, 4.7.1, 4.7.2, or 4.8 provides a particular .NET Framework’s version of the reference assemblies, language packs, and IntelliSense files for use in an integrated development environment such as Visual Studio. If you’re using Visual Studio, the developer pack or targeting pack also adds the installed version of .NET Framework to the target choices when you create a new project. Choose one of the following:
- .NET Framework 4.8.1
- .NET Framework 4.8
- .NET Framework 4.7.2
- .NET Framework 4.7.1
- .NET Framework 4.7
- .NET Framework 4.6.2
- .NET Framework 4.6.1
- .NET Framework 4.6
- .NET Framework 4.5.2 to install version 4.5.2 on Windows 8.1 or earlier, Visual Studio 2013, Visual Studio 2012, or other IDEs.
- .NET Framework 4.5.1 to install version 4.5.1 on Visual Studio 2012 or other IDEs.
From the developer pack download page, choose Download. Next, choose Run or Save, and follow the instructions when prompted. You can also install the developer pack or targeting pack for a specific version of .NET Framework by selecting it from the optional components in the .NET desktop development workload in the Visual Studio Installer, as the following figure shows.
:::image type=»content» source=»media/guide-for-developers/visual-studio-framework.png» alt-text=»Visual Studio installer with .NET Framework options selected.» lightbox=»media/guide-for-developers/visual-studio-framework-large.png»:::
When you target a particular version of .NET Framework, your application is built by using the reference assemblies that are included with that version’s developer pack. At run time, assemblies are resolved from the Global Assembly Cache, and the reference assemblies are not used.
When building an application from Visual Studio or using MSBuild from the command line, MSBuild may display error MSB3644, «The reference assemblies for framework «framework-version» were not found.» To address the error, download the developer pack or the targeting pack for that version of .NET Framework.
To install or download the .NET Framework redistributable
Installers download .NET Framework components for an app or control that targets those versions of .NET Framework. These components must be installed on each computer where the app or control runs. These installers are redistributable, so you can include them in the setup program for your app.
The download page is provided in several languages, but most of the downloads are provided in English only. For additional language support, you must install a language pack.
Two types of redistributable installers are available:
-
Web installer (web bootstrapper) downloads the required components and the language pack that matches the operating system of the installation computer from the web. This package is much smaller than the offline installer but requires a consistent Internet connection. You can download the standalone language packs to install additional language support.
-
Offline installer (standalone redistributable) contains all the required components for installing .NET Framework but doesn’t contain language packs. This download is larger than the web installer. The offline installer doesn’t require an internet connection. After you run the offline installer, you can download the standalone language packs to install language support. Use the offline installer if you can’t rely on having a consistent Internet connection.
Both web and offline installers are designed for x86-based and x64-based computers (see system requirements), but do not support Itanium-based computers.
-
Open the download page for the .NET Framework version you want to install:
- .NET Framework 4.8.1
- .NET Framework 4.8
- .NET Framework 4.7.2
- .NET Framework 4.7.1
- .NET Framework 4.7
- .NET Framework 4.6.2
- .NET Framework 4.6.1
- .NET Framework 4.6
- .NET Framework 4.5.2
- .NET Framework 4.5.1
- .NET Framework 4.5
-
Select the language for the download page. This option does not download the localized resources of .NET Framework; it only affects the text displayed on the download page.
-
Choose Download.
-
If prompted, select the download that matches your system architecture, and then choose Next.
-
When the download prompt appears, do one of the following:
-
If you want to install .NET Framework on your computer, choose Run, and then follow the prompts on your screen.
-
If you want to download .NET Framework for redistribution, choose Save, and then follow the prompts on your screen.
-
-
If you want to download resources for additional languages, follow the instructions in the next section to install one or more language packs.
[!NOTE]
If you encounter any problems during the installation, see Troubleshooting.
Installation notes:
-
.NET Framework 4.5 and later versions replace .NET Framework 4.0. When you install these versions on a system that has .NET Framework 4 installed, the assemblies are replaced.
-
Uninstalling .NET Framework 4.5 or later versions also removes pre-existing .NET Framework 4 files. If you want to go back to .NET Framework 4, you must reinstall it and any updates to it. See Installing the .NET Framework 4.
-
You must have administrative credentials to install .NET Framework 4.5 or later versions.
-
The .NET Framework 4.5 redistributable was updated on October 9, 2012 to correct an issue related to an improper timestamp on a digital certificate, which caused the digital signature on files produced and signed by Microsoft to expire prematurely. If you previously installed the .NET Framework 4.5 redistributable package dated August 16, 2012, we recommend that you update your copy with the latest redistributable from the .NET Framework download page. For more information about this issue, see Microsoft Security Advisory 2749655.
To install language packs
Language packs are executable files that contain the localized resources (such as translated error messages and UI text) for supported languages. If you don’t install a language pack, .NET Framework error messages and other text are displayed in English. Note that the web installer automatically installs the language pack that matches your operating system, but you can download additional language packs to your computer. The offline installers don’t include any language packs.
[!IMPORTANT]
The language packs don’t contain the .NET Framework components that are required to run an app, so you must run the web or offline installer before you install a language pack. If you have already installed a language pack, uninstall it, install the .NET Framework, and then reinstall the language pack.
-
Open the language pack download page for the .NET Framework version you’ve installed:
- .NET Framework 4.8.1
- .NET Framework 4.8
- .NET Framework 4.7.2
- .NET Framework 4.7.1
- .NET Framework 4.7
- .NET Framework 4.6.2
- .NET Framework 4.6.1
- .NET Framework 4.6
- .NET Framework 4.5.2
- .NET Framework 4.5.1
- .NET Framework 4.5
-
In the language list, choose the language you want to download, and wait a few seconds for the page to reload in that language.
-
Choose Download.
The following table lists the supported languages.

.NET Framework run-time is a Microsoft product used to run applications made with Visual Studio. If you read the system requirements of most of the modern software for Windows, you will see that most of them require .NET Framework to be installed on the computer so that the application can be installed and run properly.
Recently Microsoft announced an open-source version of .NET which means that now .NET can be made available to other platforms as well like Linux and Mac.
If you are a developer or an advanced user, you will need multiple versions of .NET Framework to be installed on the same system for testing and other purposes. I find it quite difficult to find and then download each version from Microsoft’s website as the downloads are scattered all around. The purpose of this page is to organize all the download links of .NET Framework in one place so that you can download your desired version with a single click.

.NET Framework Runtime 4?
The Microsoft .NET Framework 4 redistributable package installs the .NET Framework runtime and associated files that are required to run and develop applications to target the .NET Framework 4. The Microsoft .NET Framework is a comprehensive and consistent programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes.
Important Note:
All .NET Framework versions since .NET Framework 4 are in-place updates, so only a single 4.x version can be present on a system. In addition, particular versions of the .NET Framework are preinstalled on some versions of the Windows operating system.
This means that:
- If there’s a later 4.x version installed on the machine already, you can’t install a previous 4.x version.
- If the OS comes preinstalled with a particular .NET Framework version, you can’t install a previous 4.x version on the same machine.
- If you install a later version, you don’t have to first uninstall the previous version.
You can use .NET Runtime version 4 along with the older versions of .NET Runtimes. That means the .NET Framework 4 works side by side with older Framework versions. Any software that was developed based on earlier versions of the Framework will continue to run on the version targeted by default. The .NET Framework for Windows is a software development platform for building applications for the web, Windows, Windows Phone, Windows Server, and Microsoft Azure. It consists of the common language runtime (CLR) and the .NET Framework class library, which includes a broad range of functionality and support for many industry standards.

Microsoft .NET Framework — это цифровая платформа, позволяющая создавать, корректно запускать и использовать различные приложения или игры, при создании которых, части одного конкретного приложения пишутся разными программными кодами. Эта платформа представляет из себя цифровую среду, в которой разные коды отдельно взятого приложения компилируется в один переходящий код, который в свою очередь понятен самой платформе Framework. Затем переходящий код компилируется в понятный код для непосредственно той операционной системы, под которую разрабатывалось приложение. Например для Windows 7/8/10
Установить данную платформу можно различными способами.
- Установив операционную систему, пакет обновлений которой уже включает в себя эту платформу.
- Скачать Net Framework а затем установить. (Официальные ссылки у нас на сайте)
- Установить в качестве дополнительного ПО при установке игры.
- Автоматически установить, используя «Центр обновления Windows»
Бывают случаи: Что во время запуска игры или приложения на экране всплывает окно примерного содержания: «(имя приложения) требует наличие .НЕТ Фреймворк. Пожалуйста скачайте и установите Net Framework 3.5 или выше.» Что делает запуск данного приложения невозможным без этой платформы. Если у вас установлена Microsoft Net Framework 4.7, то это не означает что, вам не нужны более старые версии. Вам понадобится установить и Microsoft Net Framework 4 и предыдущие версии.

The Microsoft .NET Framework 4 is a software component which you can add to the Microsoft Windows operating system. It provides a large body of pre-coded solutions to common program requirements, and manages the execution of programs written specifically for the framework.
The Microsoft .NET Framework 4 focuses on the core pillars of developer experience, support for the latest platforms, targeted experiences for specific application types, and core architecture improvements.
The Microsoft .NET Framework 4 is a key Microsoft offering, and is intended to be used by most new applications created for the Windows platform.
The pre-coded solutions in the namespaces form the framework’s class library and cover a large range of programming needs in areas including the user interface, data access, cryptography, web application development, numeric algorithms, and network communications. The programmers use functions of the class library and combine them with their own code to produce applications.
Programs written for the .NET Framework execute in a software environment that manages the program’s runtime requirements. This runtime environment, which is also a part of the .NET Framework, is known as the Common Language Runtime (CLR).
The CLR provides the appearance of an application virtual machine, so that programmers need not consider the capabilities of the specific CPU that will execute the program. The CLR also provides other important services such as security mechanisms, memory management, and exception handling.
The class library and the CLR together compose the .NET Framework. The framework is intended to make it easier to develop computer applications and to reduce the vulnerability of applications and computers to security threats.
Microsoft .NET Framework 4 new features and improvements:
- Improvements in Common Language Runtime (CLR) and Base Class Library (BCL)
- Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.
- Improvements in Data Access and Modeling
- Improvements in Windows Presentation Foundation (WPF)
- Enhancements to ASP.NET
- Improvements to Windows Workflow (WF) that enable developers to better host and interact with workflows.
- Improvements to Windows Communication Foundation (WCF). Such as support for WCF Workflow Services enabling workflow programs with messaging activities, correlation support. Additionally. .NET Framework 4 provides new WCF features such as service discovery, routing service, REST support, diagnostics, and performance.
- Innovative new parallel programming features such as parallel loop support, Task Parallel Library (TPL), Parallel LINQ (PLINQ), and coordination data structures which let developers harness the power of multi-core processors.
What;s New in Microsoft .NET Framework 4:
- Improvements in Common Language Runtime (CLR) and Base Class Library (BCL)
- Performance improvement including better multicore support, background garbage collection, and profiler attach on server.
- New memory mapped file and numeric types.
- Easier debugging including dump debugging, Watson minidumps, mixed mode debugging for 64 bit and code contracts.
- For a comprehensive list of enhancements to CLR and BCL go here.
- Innovations in the Visual Basic and C# languages, for example statement lambdas, implicit line continuations, dynamic dispatch, and named/optional parameters.
- Improvements in Data Access and Modeling
- The Entity Framework enables developers to program against relational databases using .NET objects and Language Integrated Query (LINQ). It has many new features, including persistence ignorance and POCO support, foreign key associations, lazy loading, test-driven development support, functions in the model, and new LINQ operators. Additional features include better n-tier support with self-tracking entities, customizable code generation using T4 templates, model first development, an improved designer experience, better performance, and pluralization of entity sets.
- WCF Data Services is a component of the .NET Framework that enables you to create REST-based services and applications that use the Open Data Protocol (OData) to expose and consume data over the Web. WCF Data Services has many new features, including enhanced BLOB support, data binding, row count, feed customization, projections, and request pipeline improvements. Built-in integration with Microsoft Office 2010 now makes it possible to expose Microsoft Office SharePoint Server data as an OData feed and access that data feed by using the WCF Data Services client library.
