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 Store (developer portal, back-end services, reporting/analytics and process)
  • Windows Stores (Windows and Windows Phone)

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:

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. [UWP] Media Player playback cancellation through phone call or other media app

    I think I found a problem in Media Player. The problem happens on phone if media player is paused from another media app. In this case will be fired only MediaPlayer.PlaybackSession.PlaybackStateChanged event and it is not possible to detect whether app was paused through user or system. But if phone calls then will be simulated SystemMediaTransportControls pause button click (MediaPlayer.SystemMediaTransportControls.ButtonPressed event) and on phone call I can correctly stop my player and change some states. Why is it so? I think in first case must be fired ButtonPressed event too like it happens on phone call. Please add that capability.

    • Major shostopper: all JavaScript apps using camera preview will crash after latest Windows Update 10.0.15063.608!

      Each JavaScript app that uses a Video element in the UI and calls the play() function to stream the video preview from camera to the app page will Crash after recent Windows 10 update 10.0.15063.608

      You can easily reproduce the behaviour using your own sample code at:
      https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CameraGetPreviewFrame/js

      or

      https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/CameraStarterKit/js

      This crash occurs in all JavaScript apps that use the MediaCapture API to display camera Video previews.

      For this reason apps programmed in JavaScript that use Video or photo capturing are from now on non-functional in Windows 10.

      • Provide a Dispose method for UWP BitmapImage

        It would be very useful to be able to immediately release the memory held by a UWP BitmapImage (which can be significant for large images). I am preloading images for speed and I need to release the memory immediately when no longer needed to prevent memory failures, but setting the reference to null and even calling GC.Collect() immediately does not always result in an immediate release of memory.

        I've looked into using a SoftwareBitmapSource instead but this is a lot slower and uses more memory and I'm not 100% sure whether its Dispose method works (doesn't affect memory shown in…

          • HeaderedContentControl

            Please add HeaderedContentControl to the community toolkit. It is just few lines of code, but useful, since content with some header is present everywhere in the UI. More reasoning about it here: https://github.com/Microsoft/UWPCommunityToolkit/issues/995

            • Add Shadows option to UI Elements on XAML

              Add shadow option to XAML UI Elements.
              Example usage: <Image Source="ImageLocation.png" Shadow="5,5,5,5"/>
              Each number represents the shadow in each side.

              Why? One of basic fluent guidelines are shadows, so it should be easier to devs use it, without the need of 3rd party toolkit or calling the Composition directly.

                • Rome SDK for Xamarin.Forms

                  Could you add support of Xamarin.Forms to the Project Rome SDK?
                  I've tried to use the Microsoft.ConnectedDevices.Xamarin.Droid 0.4.0 with Xamarin.Forms apps, but it's difficult because the platform related methods - such as oAuth - are tied to the implementation of Android Activity.

                    • Provide a class in Windows.Services.Store namespace that can be used to simulate license info during testing.

                      The Windows.Services.Store namespace does not provide a class that you can use to simulate license info during testing. If you use the Windows.Services.Store namespace to implement in-app purchases or trials, you must publish your app to the Store and download the app to your development device to use its license for testing.

                      Provide funtionality similar to CurrentAppSimulator class found in Windows.ApplicationModel.Store namespace.

                      • 15.4.3 / designer crash

                        I reported that since studio 15.4.3 the designer crash due to attached properties

                          • Cannot use Windows SDK args, like /list, if SDK already installed

                            Wanted to use /list to work on automating the installer for a container image, and there's a ****** check in place that blocks this scenario because the SDK is already installed.

                            Repro:
                            1. Download Windows SDK on a machine with Windows SDK installed
                            2. Try executing winsdksetup.exe /list

                                • ucrtbase bug: _wspawnve is broken

                                  There is a serious bug in CRT (ucrtbase) which is part of Windows 10.
                                  The long story (please read it, since it contains all information about this bug): https://youtrack.jetbrains.com/issue/PY-17069#comment=27-1803709

                                  The short story:
                                  _wspawnve is broken when launched from Explorer (not cmd) because ``cenvarg.cpp`` expects undocumented environment variable ``=C`` (covered here: https://blogs.msdn.microsoft.com/oldnewthing/20100506-00/?p=14133) and this variable is not provided by Explorer.

                                  Tool to reproduce.

                                  ```
                                  #include<process.h>
                                  // Works from cmd.exe, but not from Explorer on Win10 :)
                                  void main() {
                                  const wchar_t* const args[] = {L"c:\\windows\\system32\\cmd.exe", L"/?", NULL};
                                  const wchar_t* const envs[] = { L"FOO=BAR", NULL};
                                  int r;

                                      You may wish to consider my FlipPdfViewerControl for inclusion in the toolkit. It is a compendium of various PDF viewer tutorials rolled into a single user control.

                                      I have no doubt it could be improved by community involvement. You may find it here:

                                      https://github.com/Swifter/FlipPdfViewer

                                      The documentation may be found here:
                                      https://swifter.github.io/FlipPdfViewerControl/PdfProject.html

                                      • LaunchUriAsync with default video/audio player

                                        Allow app to launch URI with http schema in default video or audio player (not only store player, win32 apps support will be great).

                                        Now in current API if try to open http-URI with Launcher.LaunchUriAsync and option { ContentType = "video/mp4" }, it will opened in default web-browser.

                                        • Cortana Extensions

                                          A way to create the Voice Command Definition (VCD.xml) for Cortana using C#. Currently here: https://github.com/WilliamABradley/CortanaExtensions
                                          It was inspired by NotificationExtensions, where you can create the Cortana VCD.xml using C# instead of figuring out how to define the XML yourself.
                                          This can be really helpful if you want to easily create a Multi-Lingual Cortana Experience, if you use RESW. As well as a RESW File Code Generator (Or RESX), and a tool like the MultiLingual Toolkit.
