Syndication sample

Shows how to retrieve feeds from a web service using classes in the Windows.Web.Syndication namespace in your Universal Windows Platform (UWP) app. This sample is provided in the JavaScript, C#, and C++ programming languages.

Note: This sample is part of a large collection of UWP feature samples. If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

This sample demonstrates the following features:

• Use the SyndicationClient class and class members to retrieve a web feed.
• Use the SyndicationItem class and class members to display items in a web feed.

Note  Use of this sample requires Internet or intranet access in order to retrieve feeds.

Network capabilities

This sample requires that network capabilities be set in the Package.appxmanifest file to allow the app to access the network at runtime. These capabilities can be set in the app manifest using Microsoft Visual Studio.

To build the sample, set the following network capabilities:

• Internet (Client & Server): This sample has complete access to the network for both client operations (outbound-initiated access) and server operations (inbound-initiated access). This allows the app to download various types of content from an HTTP server and upload content to an HTTP server located on the Internet or on a local intranet. This is represented by the Capability name = "internetClientServer" tag in the app manifest.

  Private Networks (Client & Server): The sample has inbound and outbound network access on a home or work network (a local intranet). This allows the app to download various types of content from an HTTP server and upload content to an HTTP server located on a local intranet. The Private Networks (Client & Server) capability is represented by the Capability name = "privateNetworkClientServer" tag in the app manifest.

For more information on network capabilities, see How to set network capabilities.
