Microsoft Visual Studio Is an Integrated Development Environment (also known as IDE). It is a product from Microsoft. It is primiraly used to develop console and graphical user interface applications along with Windows Forms applications, web sites, web applications, and web services in both native code together with managed code for all platforms supported by Microsoft Windows, Windows Mobile, Windows CE, .NET Framework, .NET Compact Framework and Microsoft Silverlight.

Visual Studio, like any other IDE, includes a built in code editor which supports syntax highlighting and code completion using IntelliSense. The intellisense is provided for variables, functions and methods, language constructs like loops and queries. IntelliSense is supported for the included languages, as well as for XML and for Cascading Style Sheets and JavaScript when developing web sites and web applications. Autocomplete suggestions are popped up in a modeless list box, overlaid on top of the code editor. In Visual Studio 2008 onwards, it can be made temporarily semi-transparent to see the code obstructed by it. The code editor is used for all supported languages.
