Windows+Phone

Windows Phone is a closed-source, proprietary framework for mobile devices that includes an operating system, middleware and key applications (e-mail, browser, media player and the like). It is owned and developed by Microsoft Corporation. Its latest iteration is called **Windows Phone 8**.

Windows Phone 8 shares portions of the Windows NT kernel kernel with other contempoarary versions of WIndows, such as Windows 8. Previous versions of Windows Phone were based on the Windows CE kernel.



The most common programming language for the application logic is C#, a Java-like language developed by Microsoft and used almost exclusively in Microsoft-related products. The user interface is declared with the Extensible Application Markup Language (XAML), a proprietary extension of XML developed by Microsoft.
