Editing Code completion (section)

IntelliSense is [[Microsoft]]'s implementation of code completion, best known in [[Visual Studio]]. It was first introduced as a feature of a mainstream Microsoft product in 1996<ref>{{Cite web |title=Microsoft KB Archive/165524 - BetaArchive Wiki |url=https://www.betaarchive.com/wiki/index.php/Microsoft_KB_Archive/165524#:~:text=A,Visual%20SourceSafe%20version%20control |access-date=2023-11-19 |website=www.betaarchive.com}}</ref> building on many already invented concepts of code completion and syntax checking, with the Visual Basic 5.0 Control Creation Edition, which was essentially a publicly available prototype for [[Visual Basic]] 5.0.<ref>{{Cite web |date=1996-10-28 |title=Microsoft Introduces Visual Basic 5.0, Control Creation Edition |url=https://news.microsoft.com/1996/10/28/microsoft-introduces-visual-basic-5-0-control-creation-edition/ |access-date=2023-11-19 |website=Stories |language=en-US}}</ref> Initially, Visual Basic IDE was the primary "test bed" for the technology, but IntelliSense was incorporated into [[Visual FoxPro]] and [[Visual C++]]<ref>{{Cite web |date=1998-06-29 |title=Microsoft Introduces Visual C++ 6.0 |url=https://news.microsoft.com/1998/06/29/microsoft-introduces-visual-c-6-0/ |access-date=2023-11-19 |website=Stories |language=en-US}}</ref> in the Visual Studio 97 timeframe (one revision after first seen in Visual Basic). Because it was based on the introspection capabilities of [[Component Object Model|COM]], the Visual Basic versions of IntelliSense were always more robust and complete than the 5.0 and 6.0 (97 and 98 in the Visual Studio naming sequence) versions of Visual C++, which did not have the benefit of being entirely based on COM. These shortcomings (criticized by many VC++ developers since the 97 release) have been largely corrected in the [[Microsoft .NET|.NET]] product lines. For example, one of the most requested capabilities missing from the pre-.NET products was support for [[Generic programming|templates]], which is now fully implemented.<ref>[http://msdn.microsoft.com/en-us/library/hcw1s69b.aspx Using IntelliSense].

IntelliSense has entered a new phase of development with the unified [[Visual Studio.NET]] environment first released in 2001, augmented by the more powerful introspection and code documentation capabilities provided by the .NET framework. IntelliSense is now supported by the Visual Studio editors for [[C++]], [[C Sharp (programming language)|C#]], [[J Sharp|J#]], [[Visual Basic]], [[XML]], [[HTML]] and [[XSLT]] among others. As of [[Visual Studio 2005]], IntelliSense is now activated by default when the user begins to type, instead of requiring marker characters (though this behavior can be turned off). The [[Integrated development environment|IDE]] has the capability of inferring a greater amount of context based on what the developer is typing, to the point that basic language constructs such as {{mono|for}} and {{mono|while}} are also included in the choice list. In 2017 Microsoft announced IntelliCode,<ref>[https://visualstudio.microsoft.com/services/intellicode/ Visual Studio IntelliCode]</ref> which uses machine learning to infer exactly which language or library feature is likely to be intended at every keystroke. Initially available as an extension for C# only, it is expected to be built in to future releases of Visual Studio.

Visual Studio 2022 includes artificial-intelligence features, such as [[GitHub Copilot]], which can automatically suggest entire lines of code based on surrounding context.

Other Microsoft products that incorporate IntelliSense include [[Microsoft Expression Web|Expression Web]], [[Microsoft FrontPage|FrontPage 2003]], [[Microsoft Small Basic|Small Basic]], the [[Visual Basic for Applications]] IDEs in the [[Microsoft Office]] products, [[Visual Studio Code]] and many others. [[SQL Server 2008|SQL Server 2008 Management Studio]] has autocomplete for the SQL syntax.
