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 1.0 were released.<ref>{{cite web |url=http://ben.skyiv.com/clrversion.html |title=Framework Versions |archiveurl=https://web.archive.org/web/20080504160116/http://ben.skyiv.com/clrversion.html |archivedate=4 May 2008 |deadurl=yes |df=dmy-all |access-date=19 December 2010 }}</ref> The first version of .NET Framework was released on 13 February 2002, bringing [[managed code]] to [[Windows NT 4.0]], [[Windows 98|98]], [[Windows 2000|2000]], [[Windows ME|ME]] and [[Windows XP|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 computing|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.

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 [[Common Language Runtime|CLR]] as .NET Framework 2.0.<ref>{{cite web |url=http://msdn.microsoft.com/netframework/aa663314.aspx |title=.NET Framework 3.0 Versioning and Deployment Q&A |accessdate=1 June 2008}}</ref> 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 [[Application programming interface|API]] based on [[XAML]] markup language, which uses [[3D computer graphics]] hardware and [[Direct3D]] technologies<ref>{{Cite web|url = http://msdn.microsoft.com/en-us/library/ms754130.aspx|title = Windows Presentation Foundation|date = |accessdate = 1 September 2014|website = [[MSDN]]|publisher = [[Microsoft]]|last = |first = }}</ref>
 
* [[Windows Communication Foundation]] (WCF), formerly code-named Indigo: A service-oriented messaging system which allows programs to interoperate locally or remotely similar to [[web service]]s
 
* [[Windows Workflow Foundation]] (WF): Allows building task automation and integrated transactions using [[workflow]]s
 
* [[Windows CardSpace]], formerly code-named InfoCard: A software component which securely stores a person's digital identities and provides a unified [[interface (computing)|interface]] for choosing the identity for a particular transaction, such as logging into a website
 
 
 
.NET Framework 3.0 is supported on [[Windows XP]], [[Windows Server 2003|Server 2003]], [[Windows Vista|Vista]], [[Windows Server 2008|Server 2008]], and [[Windows Server 2008 R2|Server 2008 R2]].<ref name="depend"/>  Applications utilizing .NET Framework 3.0 will also run on computers with .NET Framework 3.5 installed, which supports additional operating systems.

==.NET Framework 3.5==
 
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|Language Integrated Query (LINQ)]]. These changes do not affect applications written for version 2.0, however.<ref>{{cite web|url=http://www.hanselman.com/blog/CommentView.aspx?guid=7cd75505-192f-4fef-b617-e47e1e2cb94b |title=Catching RedBits differences in .NET 2.0 and .NET 2.0SP1 |accessdate=1 June 2008 |archiveurl=https://web.archive.org/web/20080430003858/http://www.hanselman.com/blog/CommentView.aspx?guid=7cd75505-192f-4fef-b617-e47e1e2cb94b |archivedate=30 April 2008 |deadurl=no |df=dmy }}</ref>
 
 
 
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 License#Microsoft Reference Source License (Ms-RSL)|Microsoft Reference Source License]].<ref name="sourcerelease">{{cite web|url=http://weblogs.asp.net/scottgu/archive/2007/10/03/releasing-the-source-code-for-the-net-framework-libraries.aspx |title=Releasing the Source Code for the NET Framework |author=[[Scott Guthrie]] |date=3 October 2007 |accessdate=15 September 2010 |archiveurl=https://web.archive.org/web/20100907233621/http://weblogs.asp.net/scottgu/archive/2007/10/03/releasing-the-source-code-for-the-net-framework-libraries.aspx |archivedate=7 September 2010 |deadurl=no |df=dmy }}</ref>

===Service Pack 1 {{Anchor|.NET Framework 3.5 SP1}}===
 
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,<ref>{{cite web|url=http://msdn.microsoft.com/vstudio/products/cc533447.aspx |title=Visual Studio 2008 Service Pack 1 and .NET Framework 3.5 Service Pack 1 |accessdate=7 September 2008 |archiveurl=https://web.archive.org/web/20080708235537/http://msdn.microsoft.com/vstudio/products/cc533447.aspx |archivedate=8 July 2008 |deadurl=no |df=dmy }}</ref> 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{{Not a typo|.}}Abstraction and System.Web{{Not a typo|.}}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|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).
 
 
 
====.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&nbsp;MB is significantly smaller than the full framework and only installs components that are the most relevant to [[desktop computer|desktop]] applications.<ref>{{cite web

=== .NET for Metro-style apps ===
 
[[Metro-style app]]s 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 Sharp (programming language)|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]].<ref>{{cite web|title=.NET for Windows apps|url=https://msdn.microsoft.com/en-us/library/windows/apps/br230232.aspx|website=[[MSDN]]|publisher=[[Microsoft]]|accessdate=26 January 2016}}</ref>
