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 final 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]

.NET Framework 3.0

Elements of the Microsoft .NET Framework version 3.0

.NET Framework 3.0, formerly called WinFX,[48] 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.[49] 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:

.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.[51]

Service Pack 2

.NET Framework 3.0 Service Pack 2 was released on 11 August 2008.[52]

.NET Framework 3.5

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.[53]

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.[54]

.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.

Although .NET Framework 3.5 is over 10 years old, it is also shipped as Windows Container image, allowing old applications that based on .NET Framework 2.0–3.5 to run in container environment.[55]

Service Pack 1

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,[56] 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

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.[57] 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.[58]

.NET Framework 4.0

Key focuses for this release are:

.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.

.NET for Metro-style apps

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.[85]

Core features

  • 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.
