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?

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.

    • Please support .Net Standard 2.0 on Windows 10 Mobile

      I have published 2 UWP apps. MS has abandon Windows Phone. My apps are now Desktop only. This was not my intension when starting development. I am now forced to develop Xamarin versions of my apps with .Net Standard 2.0. This will cost me much time and trouble. There is no Window device/emulator with a form factor below 7". If Window will never again support those small devices, it is sad but understandable. But if Windows will support smaller devices
      in the future, MS should support W10M at least for development of UWP apps in the mean time.The support of…

      • [Bug report] system lock random files

        The win32 app which install from windows store will cache random files in `LocalCache` directory.

        Today I try to update vscode (user installer), the updater show the code.exe was lock by system and cannot be overwrite.

        I am try to use taskmgr or other software to find the code.exe file handle, but found nothing.

        I use everything to search code.exe, I found three code.exe and two of them was in
        [the-package-id]\LocalCache\Local\Programs\Microsoft VS Code.

        Base on package id, I quit two win32 app, then updater succeed.

        • Can you bring back cppwinrt's xaml programmatic support

          Earlier this year (but with cppwinrt still new!) I created a complete complex UI using cppwinrt's programmatic support for xaml: e.g. StackPanel(), Grid(), RowDefinitions, Column Definitions, Children().append(), etc. Quite a lot of work but it easy to read and ran great. Is all of that gone? Or is there still a way to use those cppwinrt features?

          • UWP DatagramSocket does not receive data until after data is sent on the socket.

            See: https://stackoverflow.com/a/39767527 and https://stackoverflow.com/a/39768462

            You can also use https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/DatagramSocket to demonstrate this issue. Use scenario 5 to listen for multicast traffic and observe nothing is received until after hitting the send button.

            • Partial stars in RatingControl

              It would be nice to use rating control with partial stars.
              Example:
              https://imgur.com/a/SoHMsyd

              It can be a Step property.
              For example: Step = 0.5 and MaxValue = 5.

              Thanks!

              • 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.

                  • ItemsChangedEventArgs.Action is an int instead of a CollectionChange enum

                    The Action property is an int for some reason, but appears to just be a CollectionChange enum. It should use the enum as its type instead of an unknown int value.

                    • Delete Ink by point control

                      Have you experienced the stroke deletion using the standard InkCanvas/InkTollbar against the ink deletion experience on the Sketchpad app?
                      The Sketchpad app give you a way more natural to delete strokes because it allows you to delete ink by single point, like an eraser on the real life.
                      At the moment the UWP APIs does not expose such a way of erasing strokes, you can only erase the whole stroke, and in order to achieve the ink deletion by point there is a lot of code to write as well as having the appropriate know how.
                      What do you think…

                      • ScatterView control to support the SurfaceHub / multiuser development

                        As discussed here https://www.youtube.com/watch?v=e8qTD5g14ks with Nikola Metulev the UX of a UWP app running on a multi-user / multi-touch device, to empower the possibility of the device itself shall be designed the way that several user can interact with the device at the same time.
                        The scatter-view idea is just the concept already applied to surface v1 and v2 tables to uwp.
                        With the upcoming Surface Hub 2s, 2x and the windows 10 collaborative displays coming i believe is time for the ScatterView to be merged into the Windows Community Toolkit.

                        • Add an API to retrieve all files from a folder that matches the speed of Win32 call

                          With UWP, getting the file count for 8k files using CreateFileQueryWithOptions or GetFilesAsync on a SSD will take 9 seconds.
                          With WPF, getting the same file count using dirInfo.GetFiles will take 10 milliseconds.

                          • BUG: Custom attached dependency property w/CreateDefaultValueCallback

                            Created a custom attached property for Page elements.
                            Added PropertyMetadata via PropertyMetadata.Create so I could specify a CreateDefaultValueCallback handler.

                            When using the custom attached property, my CreateDefaultValueCallback handler gets called over and over again, it doesn't appear to ever set the value of the attached property. I can have two lines of code, one right after the other that are both calling Get(PropertyName) on the same object/property, and each time my default value callback is executed.

                            I would expect that the default value callback only gets called once, then sets the value for that object/property.

                              Web view crash with too long URIs
                              When redirecting from a webpage to a non supported URI that is longer than 2084 characters the Webview will crash without the throwing any exception.
                              The weird part about this is that if you redirect the webview to a URI starting with http:// or https:// or you send it to a malformed URI (someting:aLotOfText) of the same length it will be able to handle it.

                              Example repository:

                                • [UWP] Add HighQualityCubic option to BitmapInterpolationMode

                                  The Windows Imaging Component WICBitmapInterpolationMode enumeration has supported the value WICBitmapInterpolationModeHighQualityCubic since Windows 10 was first released. However, the corresponding Windows.Graphics.Imaging.BitmapInterpolationMode enum has not been updated to include this value. Please add this value so we can use it in the BitmapTransform of a BitmapDedcoder method for getting pixel data or a SoftwareBitmap.

                                    In the ColorPicker control, when the IsAlphaEnabled is set to true, this is not accessible.
                                    1. The label for the RGB hex field when it accepts the alpha channel is incorrect. Currently it reads, "RGB hex...". it should read "Alpha RGB Hex" and also provide formatting requirements to prevent mistakes.

                                    2. Auto formatting is incorrect for 8digits. If I enter a 6 digit Hex value. That 6 digit hex value is by default a 100% opacity. I would expect the auto formatting to respect this. It's as simple as replacing the "0" with "F". For users with vision…

                                    • Setting Width based on ActualWidth introduces render bug

                                      When I set the width of a Grid inside a ListView.ItemTemplate to the ActualWidth of the Parent ListView, the first element won't render content. If I remove it, the first line renders correctly. If I remove/re-add that line or add a name/remove a name property, some redraw happens and the first line becomes visible. I tried to work around it to force an UpdateLayout on the elements, but to no avail.

                                      I packaged the app, tested it on a clean laptop in dev modus and it occurs there as well.

                                      I can provide the sample app that i created in…

                                      • Add a "Science" category

                                        There is no category specifically related to science apps; I think having such a category would provide a more refined ability to find such an app in the Store. The closest category (the one I'm using) is Education. Here are a couple of examples: I can envision a mobile app that is a "Tree Finder" that provides the ability to identify a tree genus/species by selecting from an imagery collection, or an Astronomical app that provides ephemeris data (position of sun, moon, planets, etc), in a graphical format. My particular application locates earthquakes on a map and allows the user…

                                        • Outlined TextBlock

                                          We can easily create an outlined text in WPF.
                                          https://docs.microsoft.com/en-us/dotnet/framework/wpf/advanced/how-to-create-outlined-text
                                          In UWP, I only found a way with Win2D, but it will draw like a picture, the layout arranges will not work (such as TextWrapping).
