Universal Windows Platform

Welcome to the Windows Platform Developer (WPDev) Feedback site. This feedback forum provides the WPDev community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center (developer portal, back-end services, reporting/analytics and process)
  • Microsoft Store

Your suggestions will be reviewed by the Windows platform developer team, providing feedback to help with planning ideas and to better understand how developers are using the development platform.

What this forum is not intended to cover or capture:

  • Windows:
  • Documentation on docs.microsoft.com
    • Sign in to give documentation feedback via Github
  • Visual Studio / .NET

If you’re new to this whole UserVoice thing, we’d like to note two important things about this site: (a) List items (and item rankings) represent community interest in features, and does not represent an actual priority list for the product team; and (b) Suggestions made using this forum will be moderated if they do not actually represent a feature request.

How can we improve the Windows dev platform?

  1. MediaCapture.InitializeAsync - throws unauthorized exception

    It seems that there is a bug, which appeard after the last WP8.1 Update. MediaCapture.InitializeAsync keeps throwing UnathorizedException. I tested it on my previously (before the update) working example and MSDN sample.

    • Trial feature should be built-in.

      The trial feature should be built-in with automatic enforcement, user prompting, disabling, etc, just as it is in the Windows Store.

      In the Windows store, I can choose trial mode for my app, and then pick the number of days I want the trial to last. From there, everything is taken care of for me. If the user uninstalls during a trial, it tracks this fact and prevents them from starting a new trial later.

      Contrast this with the Windows Phone world, where the developer indicates trial mode in the store, but has to manually track the number of days…

      • Create/Update/Delete reminders and alarms from a BackgroundAgent

        You can't add/update/delete alarms or reminders from a BackgroundAgent. It'd be great if we at least has the ability to change/edit reminders and alarms that were created by that app.

        • Media playback on emulator should match Phone

          The phone currently plays a large selection of media formats (MP4, M4V, 3GP etc) that aren't supported in the emulator. This makes apps that use these formats extremely hard to debug.

          Would be awesome if you could fix this :)

          • SwipeControl should support mouse input

            The SwipeControl control should support mouse input as well as touch input. Currently it only supports touch input.

            I appreciate that swipe controls have come out of developments around touch interfaces. However on a platform that allows for a single app to run on both desktop and touch devices I think that users will be expecting to be able to interact with the app in similar ways across devices.

            Microsoft have set precedent for this in their own apps. Outlook for example utilises a SwipeControl type arrangement (that can be interacted with using a mouse) for marking emails as read…

            • Use ContentPresenter in MasterDetailsView instead of ListView

              Currently, In MasterView, we can only use ListView. It limits the use case of MasterView. We can't use Pivot, Semantic Zoom, GridView, PullToRefresh, SlidableListItem and more. But if it accepts ContentPresenter then the limit would be endless.

              Don't fake the page navigation using Storyboard. Then devs can use Connected Animations.

              • ApplicationView - Window Size improvements

                ApplicationViewWindowingMode Enum

                For my work app, we wanted the app to launch maximised. The closet option is to launch it FullScreen but that obscures the task bar.

                Auto give little control over the first launch of the app.

                This meant that I ended up using PreferredLaunchViewSize during first launch and then Auto on subsequent launches.

                This is what I am currently using

                var currentAppView = ApplicationView.GetForCurrentView();

                currentAppView.SetDesiredBoundsMode(ApplicationViewBoundsMode.UseVisible);

                var di = Windows.Graphics.Display.DisplayInformation.GetForCurrentView();

                var size = new Size(di.ScreenWidthInRawPixels, di.ScreenHeightInRawPixels);
                size.Height -= 100;
                size.Width -= 100;

                ApplicationView.PreferredLaunchViewSize = size;

                ApplicationView.PreferredLaunchWindowingMode = ViewModelLocator.AppSettingsInstance.WindowSizeSet ? ApplicationViewWindowingMode.Auto : ApplicationViewWindowingMode.PreferredLaunchViewSize;

                ViewModelLocator.AppSettingsInstance.WindowSizeSet = true;

                This seems a bad…

                • Allow UWP apps without .NET Native

                  In 2017, .NET Native is still not mature and still has bugs. But for UWP apps to be published in the App Store, you must use .NET Native. Interestingly, Apps wrapped with Desktop Bridge do not have to use .NET Native. So, please allow UWP apps without .NET Native! (This would automatically enable us to write apps in F#, too, as a side effect).

                    • Read currently played song

                      I would like to read currently played song or content in Windows 10. Use case: As neither Groove nor Spotify have a lyrics functionality (anymore) I created a simple UWP app to manage lyrics for songs. I would like to add a function that automatically loads the lyrics to the song that is played right now.

                      To solve that, it would be enough to have read access to the System Media Transport Controls data of other apps. Following data would be great:
                      - Title
                      - Artist
                      - Album cover (optional)
                      - App name
                      - Is playing or not
                      - Is…

                        • Enable Manipulation Events for WebView.

                          Since WebView lacks support for Manipulation Events, it acts as a huge gesture eater which doesn't let its parent controls like ScrollViewer, FlipView to take control of gesture like scroll, swipe etc.
                          It becomes impossible to use a WebView along with other XAML Elements in the same view.
                          Manipulation events can help a lot in these situations.

                            Selenium can handle web based alert pop ups but unable to handle windows based alert pop ups such as the Windows to download or upload files, or the Print window. Current solution to handle this scenario is using Autoit but not the most elegant solution. It would be good see an integrated solution.

                                • C# UWP app: exception.StackTrace should include full stacktrace

                                  When an error occurs it happens a lot that exception.StackTrace is null (in the App UnhandledException handler for instance).
                                  This is in fact documented and the offical recommendation is to try/catch closer to the code (https://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.application.unhandledexception).
                                  The problem is we can't put try/catch everywhere and we would like to understand crashes but without a stacktrace it is difficult.

                                  • Low Level NFC Support to access SmartCards via ISO14443 compatible Protocoll

                                    At the moment there are only APIs for reading and writing NFC Tags. Unfortunately this is only a very small part of the NFC capabilities. With an ISO14443 Smartcard support, you would be able to communicate with Smartcards like being used in public transport or supporting payment via NFC Credit Cards.
                                    These capabilities are well supported by other platforms and I would like to see this support on WP8 too.

                                            Hey this is a good feedback. Can you tell us if you see it as an attached property (like IsRequired=“true”) ?
