Connecting to an HTTP server using System.Net.Http.HttpClient (Windows Store apps using C#/VB and XAML)
[This article is for Windows 8.x and Windows Phone 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see the latest documentation]
Use System.Net.Http.HttpClient to connect to a web service using C# or Visual Basic in a Windows Store app.
Note
The System.Net.Http and System.Net.Http.Headers namespace might not be available in future versions of Windows for use by Windows Store apps. Starting with Windows 8.1 and Windows Server 2012 R2, use Windows.Web.Http.HttpClient in the Windows.Web.Http namespace and the related Windows.Web.Http.Headers and Windows.Web.Http.Filters namespaces instead for Windows Store apps.
For desktop apps, the System.Net.Http and System.Net.Http.Headers namespaces are still recommended and will be available in future versions of Windows.
