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. 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
        }
        }
        }

        • KeyboardSelection in Selectors (ListBox, ComboBox, ListView, GridView)

          Keyboard selection in Selectors (ListBox, ComboBox, ListView, GridView) for UWP apps doesn't really work.

          I came up with a solution for this using a KeyboardSelectionBehavior, Have a look at:
          WinRT: https://reflectionit.nl/Blog/2013/windows-8-xaml-tips-creating-blend-behaviors
          Silverlight: https://www.reflectionit.nl/blog/2010/keyboard-selection-on-silverlight-listbox-and-combobox

          I think this could also be useful for the toolkit. I'm not sure if it should be a Behavior or an AttachedProperty.

          • 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.

            • Convert a company account into an individual

              I made the mistake of registering a dev account using the type company instead of individual. Now I cannot change it to individual. This is not good enough. I have to be able to change dev account type. Please make this happen as soon as possible.

              • Button in the UI (notificationcenter) to switch between different Bluetooth Devices

                Hi Dev Team,

                is it possible to get an switch for changing between different bluetooth devices. I know there is one in the notificationcenter to switch bluetooth on and off. But if you want to switch between different headphones you have to go to the settings app and connect to them directly (Example).

                I found no quick way to solve this problem.

                Thank you

                • 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…

                  • Add .webm to list of file extensions that are considered part of the video library (also .dds for pictures library)

                    It's nice that the MediaPlayer supports .webm videos, but for some reason these files are not considered as video library files, by which I mean if you register your app to open this extension and you also add the video library capability to your app, you would expect the neighboring files query to contain neighboring .webm files, but it does not. Please can you add the .webm extension to the relavent list? Also, can you do the analogous thing for .dds files but with the pictures library?

                    • UWP CommandBar SecondaryCommands KeyboardAccelerators

                      SecondaryCommands KeyboardAccelerators in a CommandBar only work until the SecondaryCommands menu is opened, then when closed they stop working. This has been tested in 1809.

                      • AppBarButton with MenuFlyout Flyout is broken in the 1809 update

                        I am targeting Windows 10 version 1809 and that is also my OS version. If I have an AppBarButton inside a CommandBar and set the Flyout of the AppBarButton to a MenuFlyout then it doesn't work properly - the MenuFlyout opens Ok, but it doesn't block the background and it's impossible to close it without clicking a MenuItem in the MenuFlyout (even clicking on the AppBarButton to try and close it doesn't work). This used to work fine before version 1809. Perhaps something got broken when the new CommandBarFlyout that's been added in 1809 was introduced.

                        A workaround is to…

                        • MediaTransportControls do not auto-hide correctly

                          MediaTransportControls no longer auto-hide correctly for UWP apps on desktop when using the mouse pointer. When the pointer is used to click the play/pause button, the transport control bar begins to hide and then immediately pops back up again. This bug does not occur with a game controller.

                          This appears to be related to the introduction of MediaTransportControls.ShowAndHideAutomatically property in Build 16299.

                          I am using Windows v1809.

                          This bug is reproducible in any app which uses the transport controls, including the XAML Controls Gallery app (under Media) available in the MS Store. The link to the app can be found…

                          • Allow UWP Thickness Struct to Individually Set Left, Right, Top and Bottom in XAML

                            In UWP it's impossible to individually specify Left, Right, Top and Bottom values in XAML for the Thickness struct. For example, the following is possible in WPF but impossible in UWP:

                            <Thickness x:Key="MyThickness"
                            Left="{StaticResource LeftOffset}"
                            Top="0"
                            Right="0"
                            Bottom="0"/>

                            UWP only allows...
                            <Thickness x:Key="MyThickness">5,0,0,0</Thickness>

                            Individual values cannot be set in XAML. This can limit common resources and re-usability and require unnecessary hard-coding of Thickness values.

                            Please add this capability to UWP Thickness.

                              • Autofill Providers (such as Password Managers)

                                Provide a way for apps to request other apps to fill input fields.

                                A good example of this is an app with a login screen. The user could fill the username and password manually or call another app that can provide those fields.

                                It's something like Android[1] and iOS Autofill Framework.

                                  • Let us delete addons in the partner center

                                    Please, give us the possibility to delete add-ons (with, without subscriptions etc) right in the Web GUI of the partner center.

                                    Right now, if you want to delete an addon in the partner center (which you have created there), you have to:

                                    Read and follow all the required manuals to delete an add-on with azure ad integration.

                                    Create an account, wired app to it, get token, app-secret, tenantId etc.

                                    Entered the needed ID also in the partner-center's section "product collections" and "adminstrator agreement".

                                    Search desperatly for a complete c# uwp exambple how to connect and proceed with a follow up…

                                      Hi, is it possible to get the active subscription count added in to the console and in to downloadable reports? We can get the number of acquisitions for IAP but this doesn't tell us about how many are currently active or anything around churn. It's very difficult to work out how many active subscribers we have.

                                      • 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…
