# RssReader sample



A mini-app for retrieving RSS feeds and viewing articles, showing MVVM and design best practices.

Users can specify the URL of a feed, view articles in a WebView control, and save favorite articles to local storage. 

This sample runs on the Universal Windows Platform (UWP) and WinUI 2.4. 



> Note - This sample is targeted and tested for Windows 10, version 2004 (10.0; Build 19041), and Visual Studio 2019. If you prefer, you can use project properties to retarget the project(s) to Windows 10, version 1903 (10.0; Build 18362).

## Features



**Note:** Features in this app are subject to change.



RssReader demonstrates:

	

* The navigation menu (hamburger menu) pattern and screen-width adaptivity using the 

  [SplitView](https://msdn.microsoft.com/library/windows/apps/windows.ui.xaml.controls.splitview.aspx) control and the 

  [AdaptiveTrigger](https://msdn.microsoft.com/library/windows/apps/windows.ui.xaml.adaptivetrigger.aspx) class.

* The Syndication APIs ([Windows.Web.Syndication](https://msdn.microsoft.com/library/windows/apps/windows.web.syndication.aspx)) 

  to retrieve RSS feed data. 

* The [DataContractSerializer](https://msdn.microsoft.com/library/windows/apps/system.runtime.serialization.datacontractserializer.aspx) class to save and 

restore app data from local storage.

* C# and XAML using the MVVM design pattern.



### June 2020 update



This update includes:



* Refactoring for WinUI 2.4 controls, specifically [ProgressBar](https://docs.microsoft.com/windows/uwp/design/controls-and-patterns/progress-controls).



### September 2016 update



This update includes:



* General cleanup, commenting, and refactoring for clarity. 

* Improved error handling and performance.

* Fixes for several bugs related to layout, navigation, browser launch, and URL handling. 



### March 2016 update



This update includes:



* A complete redesign of the UI to show effective use of color, type, images, and animated effects.

* Major improvements to layout, navigation, and window-size adaptivity to support small and large screens. 

* Use of the [WebView](https://msdn.microsoft.com/library/windows/apps/windows.ui.xaml.controls.webview.aspx) 

  control to show articles within the app. 

* The ability to rename feeds and to rearrange feeds and favorites. 



We implemented the navigation and layout patterns in this sample using code from the 

[XAML navigation menu](https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/XamlNavigation) and

[XAML master/detail](https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/XamlMasterDetail) samples in the 

[Windows-universal-samples](https://github.com/Microsoft/Windows-universal-samples) repo. These samples represent the current

minimum recommendations for these patterns, and the RssReader sample will continue to reflect this guidance in future updates. 



Please report any bugs or suggestions on the [Issues](https://github.com/Microsoft/Windows-appsample-rssreader/issues) list. 

All feedback is welcome!

## Running the sample



The default project is RssReader and you can Start Debugging (F5) or Start Without Debugging (Ctrl+F5) to try it out. 

The app will run in the emulator or on physical devices. 



**Note:** This sample assumes you have an internet connection. Also, the platform target currently defaults to ARM, 

so be sure to change that to x64 or x86 if you want to test on a non-ARM device.
