Microsoft started development on the .NET Framework in the late 1990s originally under the name of Next Generation Windows Services (NGWS). By late 2001 the first beta versions of .NET Framework 1.0 were released.[1] The first version of .NET Framework was released on 13 February 2002, bringing managed code to Windows NT 4.0, 98, 2000, ME and XP.

Since the first version, Microsoft has released nine more upgrades for .NET Framework, seven of which have been released along with a new version of Visual Studio. Two of these upgrades, .NET Framework 2.0 and 4.0, have upgraded Common Language Runtime (CLR). New versions of .NET Framework replace older versions when the CLR version is the same.
The .NET Framework family also includes two versions for mobile or embedded device use. A reduced version of the framework, the .NET Compact Framework, is available on Windows CE platforms, including Windows Mobile devices such as smartphones. Additionally, the .NET Micro Framework is targeted at severely resource-constrained devices.
.NET Framework 4.8 was announced as the last major version of .NET Framework, with future work going into the rewritten and cross-platform .NET Core platform (later, simply .NET), which shipped as .NET 5 in November 2020.[2][3] However, .NET Framework 4.8.1 was released in August 2022.[4]

The first version of the .NET Framework was released on 15 January 2002 for Windows 98, ME, NT 4.0, 2000, and XP. Mainstream support for this version ended on 10 July 2007, and extended support ended on 14 July 2009, with the exception of Windows XP Media Center and Tablet PC editions.[10]
On 19 June 2001, the tenth anniversary of the release of Visual Basic, .NET Framework 1.0 Beta 2 was released.[35]
.NET Framework 1.0 is supported on Windows 98, ME, NT 4.0 (with Service Pack 6a), 2000, XP, and Server 2003. Applications utilizing .NET Framework 1.0 will also run on computers with .NET Framework 1.1 installed, which supports additional operating systems.[36]
The .NET Framework 1.0 Service Pack 1 was released on 19 March 2002.[37]
.NET Framework 1.0 Service Pack 2 was released on 7 August 2002.[38]
.NET Framework 1.0 Service Pack 3 was released on 30 August 2004.[39]
Version 1.1 is the first minor .NET Framework upgrade. It is available on its own as a redistributable package or in a software development kit, and was published on 3 April 2003. It is also part of the second release of Visual Studio .NET 2003. This is the first version of the .NET Framework to be included as part of the Windows operating system, shipping with Windows Server 2003. Mainstream support for .NET Framework 1.1 ended on 14 October 2008, and extended support ended on 8 October 2013. .NET Framework 1.1 provides full backward compatibility to version 1.0, except in rare instances where an application will not run because it checks the version number of a library.[40]
Changes in 1.1 include:[41]
- Built-in support for mobile ASP.NET controls, which was previously available as an add-on
- Enables Windows Forms assemblies to execute in a semi-trusted manner from the Internet
- Enables Code Access Security in ASP.NET applications
- Built-in support for ODBC and Oracle Database, which was previously available as an add-on
- .NET Compact Framework, a version of the .NET Framework for small devices
- Internet Protocol version 6 (IPv6) support
.NET Framework 1.1 is supported on Windows 98, ME, NT 4.0 (with Service Pack 6a), 2000, XP, Server 2003, Vista, and Server 2008.[36][42]
The .NET Framework 1.1 Service Pack 1 was released on 30 August 2004.[43] It requires Windows NT 4.0 SP6a plus Windows Installer 2.0. It is the last version to support Windows NT 4.0 SP6a, Windows 2000 RTM-SP2 and Windows XP RTM-SP1.
Version 2.0 was released on 27 October 2005. It was also released along with Visual Studio 2005, Microsoft SQL Server 2005, and BizTalk 2006. A software development kit for this version was released on 29 November 2006.[44] Support ended on 12 July 2011. It is the last version to support Windows 98, Windows 2000 SP3, Windows ME and Windows Server 2003 RTM.[45]
Changes in 2.0 include:
- Full 64-bit computing support for both the x64 and the IA-64 hardware platforms
- Microsoft SQL Server integration: Instead of using T-SQL, one can build stored procedures and triggers in any of the .NET-compatible languages
- A new hosting API for native applications wishing to host an instance of the .NET runtime: The new API gives a fine grain control on the behavior of the runtime with regards to multithreading, memory allocation and assembly loading. It was initially developed to efficiently host the runtime in Microsoft SQL Server, which implements its own scheduler and memory manager.
- New personalization features for ASP.NET, such as support for themes, skins, master pages and webparts
- .NET Micro Framework, a version of the .NET Framework related to the Smart Personal Objects Technology initiative
- Membership provider
- Partial classes

- Language support for generics built directly into the .NET CLR
.NET Framework 2.0 is supported on Windows 98, ME, 2000 (with Service Pack 3 or higher), XP (with Service Pack 2 or higher), Server 2003, Server 2008 and Server 2008 R2.[6] Applications utilizing .NET Framework 2.0 will also run on computers with .NET Framework 3.0 or 3.5 installed, which supports additional operating systems.
The .NET Framework 2.0 Service Pack 1 was released on 19 November 2007.[46] It requires Windows 2000 with SP4.
The .NET Framework 2.0 Service Pack 2 was released on 11 August 2008.[47] It requires Windows 2000 with SP4 plus KB835732 or KB891861 update, Windows XP with SP2 plus Windows Installer 3.1. It is the last version to support Windows 2000 SP4 although there have been some unofficial workarounds to use a subset of the functionality from Version 3.5 in Windows 2000.[48]
.NET Framework 3.0, formerly called WinFX,[49] was released on 6 November 2006. It includes a new set of managed code APIs that are an integral part of Windows Vista and Windows Server 2008. It is also available for Windows XP SP2 and Windows Server 2003 as a download. There are no major architectural changes included with this release; .NET Framework 3.0 uses the same CLR as .NET Framework 2.0.[50] Unlike the previous major .NET releases there was no .NET Compact Framework release made as a counterpart of this version. Version 3.0 of the .NET Framework shipped with Windows Vista. It also shipped with Windows Server 2008 as an optional component (disabled by default).
.NET Framework 3.0 consists of four major new components:
- Windows Presentation Foundation (WPF), formerly code-named Avalon: A new user interface subsystem and API based on XAML markup language, which uses 3D computer graphics hardware and Direct3D technologies[51]
- Windows Communication Foundation (WCF), formerly code-named Indigo: A service-oriented messaging system which allows programs to interoperate locally or remotely similar to web services
- Windows Workflow Foundation (WF): Allows building task automation and integrated transactions using workflows
- Windows CardSpace, formerly code-named InfoCard: A software component which securely stores a person’s digital identities and provides a unified interface for choosing the identity for a particular transaction, such as logging into a website
.NET Framework 3.0 is supported on Windows XP, Server 2003, Vista, Server 2008, and Server 2008 R2.[6] Applications utilizing .NET Framework 3.0 will also run on computers with .NET Framework 3.5 installed, which supports additional operating systems.
.NET Framework 3.0 Service Pack 1 was released on 19 November 2007.[52]
.NET Framework 3.0 Service Pack 2 was released on 11 August 2008.[53]
Version 3.5 of the .NET Framework was released on 19 November 2007. As with .NET Framework 3.0, version 3.5 uses Common Language Runtime (CLR) 2.0, that is, the same version as .NET Framework version 2.0. In addition, .NET Framework 3.5 also installs .NET Framework 2.0 SP1 and 3.0 SP1 (with the later 3.5 SP1 instead installing 2.0 SP2 and 3.0 SP2), which adds some methods and properties to the BCL classes in version 2.0 which are required for version 3.5 features such as Language Integrated Query (LINQ). These changes do not affect applications written for version 2.0, however.[54]
As with previous versions, a new .NET Compact Framework 3.5 was released in tandem with this update in order to provide support for additional features on Windows Mobile and Windows Embedded CE devices.
The source code of the Framework Class Library in this version has been partially released (for debugging reference only) under the Microsoft Reference Source License.[55]
.NET Framework 3.5 is supported on Windows XP (with Service Pack 2 or higher), Server 2003 (with Service Pack 1 or higher), Vista, Server 2008, 7, Server 2008 R2, 8, Server 2012, 8.1, Server 2012 R2, 10, and Server 2016.[6] Starting from Windows 8, .NET Framework 3.5 is an optional feature that can be turned on or off in control panel.
.NET Framework 3.5 is also available as a Windows Container image, allowing old applications that rely on .NET Framework 2.0–3.5 to run in a container environment.[56]
The .NET Framework 3.5 Service Pack 1 was released on 11 August 2008. This release adds new functionality and provides performance improvements under certain conditions,[57] especially with WPF where 20–45% improvements are expected. Two new data service components have been added, the ADO.NET Entity Framework and ADO.NET Data Services. Two new assemblies for web development, System.Web.Abstraction and System.Web.Routing, have been added; these are used in the ASP.NET MVC framework and, reportedly, will be used in the future release of ASP.NET Forms applications. Service Pack 1 is included with SQL Server 2008 and Visual Studio 2008 Service Pack 1. It also featured a new set of controls called «Visual Basic Power Packs» which brought back Visual Basic controls such as «Line» and «Shape.» Version 3.5 SP1 of the .NET Framework shipped with Windows 7. It also shipped with Windows Server 2008 R2 as an optional component (disabled by default). It is the last version to support Windows XP SP2, Windows Server 2003 SP1 and Windows Vista RTM.
.NET Framework 3.5 SP1 Client Profile
edit
For the .NET Framework 3.5 SP1 there is also a new variant of the .NET Framework, called the «.NET Framework Client Profile», which at 28 MB is significantly smaller than the full framework and only installs components that are the most relevant to desktop applications.[58] However, the Client Profile amounts to this size only if using the online installer on Windows XP SP2 when no other .NET Frameworks are installed or using Windows Update. When using the off-line installer or any other OS, the download size is still 250 MB.[59]
Key focuses for this release are:
- Parallel Extensions to improve support for parallel computing, which target multi-core or distributed systems.[60] To this end, technologies like PLINQ (Parallel LINQ),[61] a parallel implementation of the LINQ engine, and Task Parallel Library, which exposes parallel constructs via method calls,[62] are included.
- New Visual Basic .NET and C# language features, such as implicit line continuations, dynamic dispatch, named parameters, and optional parameters
- Support for Code Contracts[63]
- Inclusion of new types to work with arbitrary-precision arithmetic (System.Numerics.BigInteger)[64] and complex numbers (System.Numerics.Complex)[65]
- Introduced Common Language Runtime (CLR) 4.0
.NET Framework 4.0 is supported on Windows XP (with Service Pack 3), Windows Server 2003 (with Service Pack 2), Vista (with Service Pack 1 or higher), Server 2008, 7 and Server 2008 R2.[6] Applications utilizing .NET Framework 4.0 will also run on computers with .NET Framework 4.5 or 4.6 installed, which supports additional operating systems. Support for .NET Framework 4.0 ended on 12 April 2016 and is no longer providing technical support, bug fixes, or security fixes for .NET Framework 4.0 vulnerabilities which may be subsequently reported or discovered. It is the last version to support Windows XP SP3, Windows Server 2003 SP2, Windows Vista SP1, Windows Server 2008 RTM, Windows 7 RTM and Windows Server 2008 R2 RTM.
Microsoft announced the intention to ship .NET Framework 4 on 29 September 2008. The Public Beta was released on 20 May 2009.[66]
On 28 July 2009, a second release of the .NET Framework 4 beta was made available with experimental software transactional memory support.[67] This functionality is not available in the final version of the framework.
On 19 October 2009, Microsoft released Beta 2 of the .NET Framework 4.[68] At the same time, Microsoft announced the expected launch date for .NET Framework 4 as 22 March 2010.[68] This launch date was subsequently delayed to 12 April 2010.[69]
On 10 February 2010, a release candidate was published.[70]
On 12 April 2010, the final version of .NET Framework 4.0 was launched alongside the final release of Microsoft Visual Studio 2010.[71]
On 18 April 2011, version 4.0.1 was released supporting some customer-demanded fixes for Windows Workflow Foundation.[72][73] Its design-time component, which requires Visual Studio 2010 SP1, adds a workflow state machine designer.
On 27 October 2011, version 4.0.2 was released supporting some new features of Microsoft SQL Server.[74][75]
On 5 March 2012, version 4.0.3 was released.[76][77]
Windows Server AppFabric
edit
After the release of the .NET Framework 4, Microsoft released a set of enhancements, named Windows Server AppFabric,[78] for application server capabilities in the form of AppFabric Hosting[79][80] and in-memory distributed caching support.
.NET Framework 4.5 was released on 15 August 2012;[81] a set of new or improved features were added into this version.[82] NET Framework 4.5 is supported on Windows Vista or later.[83][84] The .NET Framework 4.5 uses Common Language Runtime 4.0, with some additional runtime features.[85]
.NET Framework 4.5 is supported on Windows Vista (with Service Pack 2), Server 2008 (with Service Pack 2), 7 (with Service Pack 1), Server 2008 R2 (with Service Pack 1), 8, Server 2012, 8.1 and Server 2012 R2.[6] Applications utilizing .NET Framework 4.5 will also run on computers with .NET Framework 4.6 installed, which supports additional operating systems.
.NET for Metro-style apps
edit
Metro-style apps were originally designed for specific form factors and leverage the power of the Windows operating system. Two subset of the .NET Framework is available for building Metro-style apps using C# or Visual Basic: One for Windows 8 and Windows 8.1, called .NET APIs for Windows 8.x Store apps. Another for Universal Windows Platform (UWP), called .NET APIs for UWP. This version of .NET Framework, as well as the runtime and libraries used for Metro-style apps, is a part of Windows Runtime, the new platform and development model for Metro-style apps. It is an ecosystem that houses many platforms and languages, including .NET Framework, C++ and HTML5 with JavaScript.[86]
- Ability to limit how long the regular expression engine will attempt to resolve a regular expression before it times out.
- Ability to define the culture for an application domain.
- Console support for Unicode (UTF-16) encoding.
- Support for versioning of cultural string ordering and comparison data.
- Better performance when retrieving resources.
- Native support for Zip compression (previous versions supported the compression algorithm, but not the archive format).
- Ability to customize a reflection context to override default reflection behavior through the CustomReflectionContext class.
- New asynchronous features were added to the C# and Visual Basic languages. These features add a task-based model for performing asynchronous operations,[87][88] implementing futures and promises.
Managed Extensibility Framework (MEF)
edit
The Managed Extensibility Framework or MEF is a library for creating lightweight, extensible applications. It allows application developers to discover and use extensions with no configuration required. It also lets extension developers easily encapsulate code and avoid fragile hard dependencies. MEF not only allows extensions to be reused within applications, but across applications as well.[89]
- Support for new HTML5 form types.
- Support for model binders in Web Forms. These let you bind data controls directly to data-access methods, and automatically convert user input to and from .NET Framework data types.
- Support for unobtrusive JavaScript in client-side validation scripts.
- Improved handling of client script through bundling and minification for improved page performance.
- Integrated encoding routines from the Anti-XSS library (previously an external library) to protect from cross-site scripting attacks.
- Support for WebSocket protocol.
- Support for reading and writing HTTP requests and responses asynchronously.
- Support for asynchronous modules and handlers.
- Support for content distribution network (CDN) fallback in the ScriptManager control.

.NET Framework run-time is a Microsoft product used to run applications made with Visual Studio. If you read the system requirements of most modern software for Windows, you will see that most 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.
Table of Contents
What is .NET Framework?
The .NET Framework is a software development framework developed by Microsoft. It includes a large library of pre-coded solutions that developers can use to create applications for Windows, web, and mobile devices. The framework provides a programming model, a runtime, and tools to create and run applications. .NET Framework simplifies the application development process and reduces the development time due to pre-written code, making the development task less complicated.
If you are a developer or advanced user, you will need multiple .NET Framework versions to be installed on the same system for testing and other purposes. I find it 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 .NET Framework versions download links in one place so that you can download your desired version with a single click.
You can also check which versions of .NET Framework are already installed in your system.
Note: Please note that the direct download links given in the following tables are for 64-bit systems. If you want more download links for each .NET version, please click on More Info.

.NET Framework
The .NET Framework is a software development framework developed by Microsoft. It includes a large library of pre-coded solutions that developers can use to create applications for Windows, web, and mobile devices.
Price Currency:
USD
Operating System:
Windows
Application Category:
DeveloperApplication
Pros
- Less coding with OOP: .NET framework is based on the object-oriented programming model (OOP), which divides software into small pieces that are easier to manage, test, and fix.
- Reliable and scalable: .NET framework is robust and scalable, allowing developers to create large and complex applications that can handle high traffic and performance demands.
- Cross-platform: .NET framework is designed to be compatible with multiple operating systems including Windows, Linux and MacOS. It is also cloud-friendly. This gives developers more flexibility and choice in deploying their applications.
- Share Libraries: .NET Standard is a set of APIs common to all .NET platforms, such as .NET Framework, .NET Core, Xamarin, and UWP. This makes it easier to share code and libraries across different platforms.
Cons
- Limited Object-Relational Support: .NET framework does not have native support for object-relational mapping (ORM), which is a technique that maps data between objects and relational databases. Developers must use third-party tools or frameworks, such as Entity Framework or NHibernate, to achieve this functionality.
- Licensing cost: Although .NET framework itself is free, some components or tools may require a license fee. For example, Visual Studio has different editions with different prices and features. Developers may also need to pay for hosting or cloud services if they use them.
- Memory leaks: .NET framework relies on CLR to manage memory allocation and garbage collection. However, this does not guarantee that memory leaks will not occur. Developers still have to be careful with unmanaged resources, such as files or network connections, and dispose of them properly.

Clearly not an offline (full version) installer as the first part of the install process is to attempt a download…
Just so you’re aware… “offline” means no downloads.

Link to the “All in One Runtimes” (German) software was very useful, I couldn’t have found that software on my own.
Translated the website using google translate, and checked out the “changelog”, it contains all the details about the available .NET versions.

Just wanted to thank you for assembling these software titles in one place.
I was a little confused while trying to re-install a version of .net 4.5 and through this site got all the information and several utilities that made it work out perfectly.
In addition, I now know what I had done wrong and should be able to work out the problem should it occur again.
Thank you! -

My problem was will installing AutoCad the message was that NET FRAMEWORK 3.5 didn’t installed I tried many ways but non of them worked
ANY SOLUTION -
Yvette French
I suspect the reason why .NET Framework 3.0 isn’t available to download from Microsoft is it is the closest they would admit to it being buggy.
But for any that want it, maybe try this for .NET Framework 3.0 SP1:

Hi Yvette, I have checked the download link of .NET Framework 3.0 and it’s working fine. What problem did you face while downloading this specific framework?
-
Yvette French
I didn’t have a problem with .NET 3.0. It comes in Win7 but most the programs I use require .NET 4.0 which I get easily.
I gave the link as you asked if anyone knew of one to the Microsoft site.

Usman Khurshid
Yup thanks a lot for the support Yvette. It was so kind of you. I have downloaded the framework from the link you gave but it’s only the service pack, not the complete 3.0 framework. If you find the complete framework download link, do let me know

Доброго дня.
Не так уж и редко мне приходится сталкиваться с различными ошибками, связанными с пакетом Microsoft .NET Framework (чаще всего в играх, различных редакторах, программах для черчения, взять хотя бы тот же AutoCAD…). 👀
Во всех подобных проблемах, для начала, неплохо бы узнать, какая версия NET Framework требуется приложению, посмотреть есть ли она в Windows, и, если ее нет — скачать/обновить/установить.
Казалось бы, ничего сложного, но есть нюансы. О них и пойдет речь в статье… 👌
Для справки.
Вообще, NET Framework — это специальный пакет, который призван совместить между собой различное ПО, написанное на разных языках программирования (так, чтобы все работало).
По идее, можно сравнить его с кодеками. Естественно, если у вас на компьютере нет нужной версии (или она была повреждена) — то программа у вас не запустится.
А теперь, ближе к делу, разберу самое основное…
*
📌 Кстати!
Все* современные версии NET Framework доступны на офиц. страничке сайта Microsoft:
https://dotnet.microsoft.com/download/dotnet-framework
* 4.8, 4.7.2, 4.7.1, 4.7, 4.6.2, 4.6.1, 4.6, 4.5.2, 3.5 SP1
*
Решение проблем с Microsoft .NET Framework
Как узнать какие версии NET Framework у меня установлены?
Способ №1
Необходимо открыть 👉 панель управления Windows по следующему пути: Программы\Программы и компоненты (прим.: установка и удаление программ).
Далее просмотрите список установленных программ: нет ли среди них, начинающихся на «.NET…». Если в списке нет, откройте компоненты Windows (см. скриншоты ниже 👇).
Еще один способ открыть компоненты: нажать Win+R, и использовать команду optionalfeatures
Программы и компоненты
👉 Важно!
Отмечу, что в ОС Windows 8 и 10 Microsoft NET Framework не указана в списке установленных программ (чтобы посмотреть версии, необходимо открыть ссылку в меню слева «Просмотр установленных обновлений»).
В ОС Windows 10 нет возможности удаления NET Framework штатными средствами, однако, как правило возможна установка последней версии сего пакета (его обновление).
Компоненты Windows
*
Способ №2
Для просмотра и решения проблем с NET Framework есть специальная утилита «.NET Version Detector» (доступна по ссылке: 👉 http://www.asoft.be).
Она не требует установки. После запуска покажет список всех установленных версий, а также приведет ссылки на их загрузку (если вдруг чего-то не окажется — можно скачать и установить).
NET Version Detector — смотрим доступные версии NET Framework
*
Можно ли не обновлять этот пакет, ведь я раньше не обновлял его и все работало?
Большинство пользователей и не вспоминает о нем (до поры до времени…). Дело в том, что в новых версиях Windows он уже есть в комплекте (предустановлен в систему) и нет необходимости отдельно что-то скачивать или обновлять.
Кроме этого, NET Framework часто включают в установщики популярных игр, и при их инсталляции происходит и обновление этого пакета. Т.е. все действия незаметны для пользователя…
Однако, может стать так, что новая программа или игра потребует новый пакет NET Framework (или наоборот, захотите запустить что-то старое, которое потребует определенную версию сего пакета).
А дальше все просто: если нужной версии NET Framework не будет — то при запуске вы увидите ошибку (как на примере ниже 👇).
Кстати, часть ошибок может быть связана с «битой» версией NET Framework (именно поэтому, иногда рекомендуется обновлять это ПО).
Ошибка, связанная с отсутствием .NET 4.7 версии
*
📌 Ссылки на загрузку необходимых версий (ручная установка)
Во-первых, сразу хочу посоветовать: не нужно скачивать все подряд версии и пытаться переустановить каждую (чуть ниже я отмечу, какие версии рекомендованы для разных ОС).
Во-вторых, рекомендуется скачивать NET Framework только с официального сайта Microsoft (так сказать, не измененный установщик). Тем более, если вы уже столкнулись с ошибками, из-за отсутствия этого пакета…
*
👉 Способ №1. Чуть выше (👆) в статье я вам порекомендовал использовать утилиту «.NET Version Detector» — она не только покажет, какие версии пакета у вас установлены в системе, но и даст ссылки на загрузку каждой версии.
*
👉 Способ №2. Привожу ниже ссылки на официальный сайт Microsoft:
- Microsoft .NET Framework 1.1 (для Windows XP);
- Microsoft .NET Framework 3.5 SP 1 (включает .NET 2.0, 3.0; для Windows XP, Vista);
- Microsoft .NET Framework 4.0 (для Windows XP, Vista и 7);
- Microsoft .NET Framework 4.5.2 (x86/x64, для Windows 7, 8 и 8.1);
- Microsoft .NET Framework 4.8 (x64, автономный установщик! Кстати, это высоко-совместимое обновление для .NET Framework 4, 4.5, 4.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1 и 4.7.2).
*
Важно отметить, что версия 4 (скажем) обновляет предыдущую версию пакета NET Framework, поэтому для новых ОС Windows 8, 10 требуется установка (в 99,9% случаев) только последних 4-х версий.
*
Обновление NET Framework до последней версии (автоматически!) 👌
В этой заметке не могу не порекомендовать 👉 программу Driver Booster — даже если вам ненужно обновлять драйвера, все равно попробуйте воспользоваться ей!
Дело в том, что она автоматически определяет недостающие компоненты в системе, которые могут сказаться на играх (NET Framework, Visual C++ и др. пакеты), и устанавливает их. Согласитесь, это удобно!
Обратите внимание, все необходимое для игр (NET Framework, Visual C++ и др. пакеты) программа качает и ставит автоматически!
*
Можно ли удалить NET Framework (или использовать другую версию)? Что для этого необходимо?
В большинстве случаев, удалять пакет не требуется — просто нужно задействовать другую версию. Сделать это можно во вкладке «Компоненты Windows» (которую можно открыть в панели управления Windows — чуть выше в статье показано, где найти это).
Собственно, нужно-то поставить «галочку» рядом с тем пакетом, который хотите задействовать и согласиться с изменениями. ОС Windows может потребоваться загрузить недостающие файлы — делает она это сама в авто-режиме (просто потребуется подключение к интернету).
Включение NET Framework 4.7
В тех случаях, когда у вас вроде бы установлена нужная версия NET Framework, а игра (программа) все равно сыпет ошибками и «ругается» — можно попробовать удалить пакет и установить его заново.
В ряде случаев, пакет можно удалить, если открыть список установленных программ (Панель управления \ Программы \ Программы и компоненты).
Удаление происходит точно также, как и любой другой программы (см. скрин ниже 👇).
Программы и компоненты — удаляем .NET как обычную программу
В отдельных случаях, может потребовать специальная утилита: NET Framework Cleanup Tool (ссылка на блог ее разработчика Microsoft).
Утилита не нуждается в установке. Запускать ее, кстати, необходимо от имени администратора (прим.: т.е. щелкнуть по исполняемому файлу правой кнопкой мышки и в контекстном меню выбрать «запуск от имени администратора»).
Собственно, дальше будет нужно выбрать версию NET Framework, которую хотите удалить и нажать кнопку «Cleanup Now» (очистить сейчас). См. скриншот ниже. 👇
cleanup tool (работает в Windows 10)
*
Вот, собственно, и все на сегодня.
Дополнения приветствуются…
Всем успехов!
👋

.NET Framework — программный компонент основных (клиентских и серверных версий) операционных систем Windows.
Microsoft начал разработку .NET Framework в конце 1990-х годов, первоначально под названием Next Generation Windows Services (NGWS).
Развитие .NET Framework продолжается до сих пор, начиная с выпуска первой бета-версии в ноябре 2000 года. Каждая версия .NET Framework обычно содержит бета-версии, финальные релизы и пакеты обновлений.
Версии и пакеты обновлений .NET Framework доступны тремя основными способами: через механизм автообновления Windows Update, для скачивания на сайте Microsoft Download Center и в составе новых версий операционных систем[1].

Distributing the .NET Framework with DeployMaster™
DeployMaster is capable of detecting the presence of the Microsoft .NET framework, and install it if necessary. For installation, you can bundle the .NET framework redistributable for the version of .NET that your application needs with your installer. DeployMaster automatically runs it as part of the installation, as needed.
If most of your customers already have the framework installed, you can choose not to distribute it. Instead, put the URL //www.deploymaster.com/dotnetfx.html as the download URL in the installer. When using this URL, DeployMaster automatically adds a parameter to the URL to indicate the version you’ve specified in the installer. If the framework is not present, the setup program generated by DeployMaster prompts the user to download and install the framework. When the user clicks this URL in the installer, only one of the downloads below is shown. Since you didn’t click on a link in the installer, all the downloads are shown.
The application you are installing requires the Microsoft .NET framework version 1.0 to run. Windows 8 and later do not support .NET 1.0. If you are running Windows 7 or prior then you can download the Microsoft .NET Framework Redistributable 1.0 package from the Internet Archive. They archived this download from Microsoft’s servers in 2005. Microsoft has since removed it from their own servers. The 20 MB download is the full offline installer. Once you’ve installed the .NET framework, you can continue installing the application.
