Connecting to web services (XAML)
Purpose
These topics demonstrate a variety of ways to connect your app to a web service. The default choice is to use Windows.Web.Http.HttpClient, a new Windows Runtime class which is available for all languages. Apps that use C++ and XAML can also use the C++ REST SDK to create reusable code that will run in desktop applications or apps on downlevel editions of Windows as well as Linux. C++ apps that only target Windows 8, and desktop applications that target Windows 8 and later, can also use the IXMLHttpRequest2 COM interface.
The following table summarizes which API is supported on which platform (* = not recommended for apps).
| API | Languages | Platform |
|---|---|---|
| C#, Visual Basic, C++ | Windows 8.1, Windows Server 2012 R2, Windows Phone 8.1 | |
| C#, Visual Basic | Windows 8.1*, Windows Server 2012 R2*, Windows 8, Windows Server 2012, Windows 7 SP1, Windows Server 2008 R2 SP1, Windows Server 2008 SP 2, Windows Vista SP 2 | |
| XML HTTP Extended Request (IXMLHttpRequest2) | C++ | Windows 8.1*, Windows Server 2012 R2*,Windows 8, Windows Server 2012 |
| C++ | Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7 SP 1, Windows Server 2008 R2 SP1, Windows Server 2008 SP 2, Windows Vista SP 2, Linux |
