Hi dndlstlr,
You can use Launcher.LaunchUriAsync() method to open a web page to show the content.
Take a look
Launcher class, for instance the RSS feed link to Microsoft.com, we can use the following code
Launcher.LaunchUriAsync(new Uri("http://www.microsoft.com"));
If you still have problem, feel free to let me know.
