Universal Windows Platform

Welcome to the Universal Windows Platform Developer Feedback site. This site provides the Windows developer community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center (dashboard, reporting/analytics, submission process, etc.)
  • Microsoft Store

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

What this forum is not intended to cover or capture:

  • Windows consumer suggestions: Use the Windows Feedback Hub app built directly into Windows 10
  • Documentation on docs.microsoft.com: Sign in at the bottom of the page to give documentation feedback via Github
  • Visual Studio / .NET: Use the Visual Studio UserVoice site

If you’re new to UserVoice, two things to keep in mind are (a) List items (and item rankings) represent community interest in features, and not the 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 (or if too many different ideas are included in one suggestion).

How can we improve the Windows dev platform?

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. FeedbackHub link is broken in Windows 10 1809

    If you set project target version to 1809 and you try to use this official example for launching feedback hub:

    https://docs.microsoft.com/en-us/windows/uwp/monetize/launch-feedback-hub-from-your-app

    It will crash the app. Here is also full code example of this problem: https://1drv.ms/u/s!ArB5XyXKJ9ZWhjheAPPpeRA1rBWe

    It's very problematic because now 1809 is available almost everyone and feedback hub launch link itself is broken in 1809. I had to revert it to 1803 to get it working.

    • Severe Bug: Crash when using StoreServicesFeedbackLauncher to lauch Feedback Hub

      Calling StoreServicesFeedbackLauncher.LaunchAsync() in a UWP app now causes an unhandled Win32 exception if the target platform is set to Windows 10 version 1809. See https://stackoverflow.com/questions/52769958/microsofts-feedback-hub-now-crashes-my-uwp-app for another report of this.

      This means that the Feedback Hub can't be used by apps targeting Windows 10 version 1809 or later.

      I have installed the Store Services SDK using the NuGet package method as described here https://docs.microsoft.com/en-gb/windows/uwp/monetize/microsoft-store-services-sdk#install-the-sdk.

      A workaround or fix would be appreciated.

        • UWP Grid should have ShowGridLines property from WPF

          The WPF Grid control had a ShowGridLines property. This is helpful for layout debugging. This property is missing in UWP.

          • Cannot submit app to the store using cppwinrt and XAML.

            I am using cppwinrt to build an app for the store, but the XAML IDL generation seems to be generating invalid metadata.
            --------------

            The overloaded methods GetXamlType of type <App>.XamlMetaDataProvider in file <App>.winmd have the same number of in parameters without one that has DefaultOverloadAttribute. Exactly one method overload must have DefaultOverloadAttribute.

            • 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…

                • StorageFile.GetThumbnailAsync doesn't wait for thumbnail to be generated

                  Calling StorageFile.GetThumbnailAsync(ThumbnailMode.SingleItem, desiredSize) doesn't wait for the thumbnail to be generated. If there isn't one already cached, it will return an icon instead. Disposing the stream then waiting for 6 seconds then trying again correctly returns a thumbnail.

                  • TreeView event for child re-ordering

                    The UWP TreeView control lacks an event to notify that child nodes have been re-ordered due to a drag and drop. The DragItemsCompleted event is fired but there is no direct information in the arguments about whether the child ordering has changed or whether a child has been added.

                    • Bug: No crash dump for side-loaded HoloLens app when crash dump enabled

                      Apologies if this isn't the correct place to lodge this bug. If not, please redirect me :)

                      We have a Unity HoloLens app that calls into a native dll which throws an unhandled exception. The application crashes. There are no clues in the Unity logs as you'd expect, as this is native code.

                      We've enabled Crash Dumps for the app under "App Crash Dumps" in the Windows Device Portal, but whenever the crash happens, nothing appears under Crash Dumps in the same window when refreshed.

                      This definitely worked in previous Windows versions on the HoloLens. Could it be a bug…

                      • Add PaneBackground Property to NavigationView

                        It is currently possible to change the background brush of the NavigationView itself, but the Pane, in particular, is not so straightforward. Users can modify the designated ResourceKey, but cannot change this brush outside of XAML.

                        Users would benefit greatly from a "PaneBackground" property that can be set to an AcrylicBrush, etc. Especially, since the pane of this control is currently opaque by default in a WPF XAML Island.

                        To reproduce this situation, please create an "XAML island" in a WPF application. Setting the child to a NavigationView. Then, from C#, search the NavView object for a simple PaneBackground property.…

                        • Please improve the Store Certification process!

                          Please provide some consistency in the certification process. I submitted a game for publishing on Monday. It went through the entire process in about 2 hours. The game wasn't set to be published until Friday at Midnight.

                          Over the course of the week, some fixes were made to the game's code and was resubmitted for publication on Thursday around 10am.

                          It's been sitting in "Certification in Progress" now for 2 days. If it doesn't go through, I'm going to miss my published release date.

                          If you can't give a reasonable estimation on release times, maybe let us put multiple releases…

                          • Xamarin.Forms - Prevent keyboard from showing on Entry field focus

                            Currently, Entry field in Xamarin.Forms provides no functionality to prevent soft keyboard from showing up entirely. There are solution out there that will hide it but they make things even worse since now you have keyboard popping up briefly, then disappearing from the screen.

                            It feels like having a way to disable keyboard from showing up entirely on an Entry field makes sense. For example, I make my own buttons, that resemble keyboard. Tapping on each of these, puts some characters in the Entry field without showing keyboard but only when Entry field receives focus.

                            Another example, scanning with external…

                            • Infinite Canvas Export Image

                              The infinite canvas control doesn't have (that I could find) a way to export the ink as an image (PNG, JPG, GIF, etc).

                              The raw InkCanvas control underneath has ways using the StrokeContainer, but those are both private and unaccessable.

                              So can we have either a way to export, or can the underlying (my preference) InkCanvas be exposed as public?

                              Thanks!

                              • Provide a way to mark a Store submission as a bug fix so it can skip or fast-track certification

                                From my recent experiences it seems that an app submission can pass certification with no problems, but then a subsequent submission that only makes a very minor code change such as bug fix can fail certification. I accept that this will probably happen in general because full checks cannot be applied every time and different testers may pick up on different things.

                                However, it concerns me that one day I will run into the following hypothetical scenario:
                                I release a major app update which passes certification fine. I then notice a critical bug in the app which I need to…

                                    • need a way to capture a user clicking the “maximize” button on a UWP app

                                      I'm trying to find a clean way to put my app into full-screen mode (as opposed to maximized mode) when the user clicks the maximize button. The problem is, I can't find any event to identify when the maximize button is clicked.

                                      The reason I'm asking this question is I have a UWP game that runs in FullScreenMode. However, if the user wants to switch it windowed mode, they can. If they want to go back to Full Screen Mode again, there is no way for me to tell that they're trying to request that.

                                      I could add a button…

                                      • How about microsoft create a mobile version for bluestacks. I'm guessing it will be the most downloaded app

                                        It will give users the full access over android apps and it will even be much more cooler than pc blue stacks as it won't need button configuration for touchscreen options.

                                        • GUI app allows console mode

                                          UWP should allow developer to have more choice about when to enable the console mode.
                                          For example, if user click the app icon, the app run in gui mode, but if user run the app by console with arguments, app can run as in console mode.
                                          The pseudocode below shows the basal conception:

                                          //Package.appxmanifest
                                          <Applications>
                                          <Application desktop4:Subsystem="windows" iot2:Subsystem="windows">
                                          ……
                                          <Extensions>
                                          <uap5:AppExecutionAlias desktop4:Subsystem="console" iot2:Subsystem="console">

                                          // main

                                          static class Program
                                          {
                                          static void Main(string[] args)
                                          {
                                          if(args.Length==0)
                                          {
                                          global::Windows.UI.Xaml.Application.Start((p) => new App());
                                          }else
                                          {
                                          //todo: cmd mode
                                          }
                                          }
                                          }
