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?

(thinking…)

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. Allow C# style boolean conversion with x:Bind

    With x:Bind we can invert a boolean property with a ValueConverter like this:

    Visibility="{x:Bind IsLoading,Converter="{StaticResource BooleanInverseConverter}"

    But wouldn't it be much cleaner for that widely used boolean case to write just this:

    Visibility="{x:Bind !IsLoading}"

    To generated the code should be possible, and also to check in that generation whether IsLoading is a boolean or not. Even without checking, it won't compile if IsLoading wouldn't be a boolean, which is fine.

    Thanks,
    Thomas

    • Enable the Windows 10 Hyper-V Default Switch to work with Cisco AnyConnect

      The following Hyper-V networking Configuration breaks DNS name resolution on the Virtual Machine:
      1. Connecting the host to a non-corporate (remote) WiFi network.
      2. Connecting to the corporate network via Cisco AnyConnect on the host.
      3. Start a VM and connect it to the Default Switch (NAT)

      When a VM is connected to the default switch and the host is connected to the corporate network via Cisco AnyConnect, the VM looses the ability to resolve DNS addresses. The VM is able to ping both public addresses and corporate addresses; however, it is unable to resolve names on either the public…

      • 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.

        • 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.

          • 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.

            • Allow context menu verbs with file explorer integration without setting the app as default for the file type

              I want to add a context menue for *.jpg files to my app without setting the app as default app for *.jpg files.

              For example, my app wants to add the context menue "resize images" for jpg files. But I don't want to set it as default app for jpgs, as the app isn't capable for viewing images.

              • No user-consent prompt on first run of broadFileSystemAccess-capable UWP app

                When running an app which requires broadFileSystemAccess capabilities, no user-consent prompt appears on the first use. Instead, the app crashes with a System.UnauthorizedAccessException. Going into Settings to enable this privacy permission prevents the crash, and the app works normally. However, there is no prompt to enable this permission as described in the docs.

                  We are working on it. We are working on updating docs and adding in the prompt like other restricted items.

                  A code pattern like this should be a way to catch this scenario.
                  {
                  StorageFolder folder = await StorageFolder.GetFolderFromPathAsync(@"C:\Foo");
                  }
                  catch(Exception)
                  {
                  // prompt user for what action they should do then launch below
                  // suggestion could be a message prompt
                  await Launcher.LaunchUriAsync(new Uri(“ms-settings:appsfeatures-app”));
                  }

                • 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.

                        • 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…

                            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.

                              • Only compile XAML as needed

                                When building a UWP project, editing any file in the project results in every XAML file being re-compiled, regardless of if the file references anything in the changed file. In smaller projects, compilation happens fast enough to not matter. In our project with ~200 XAML files, MarkupCompilePass1 and MarkupCompilePass2 combined take 79 seconds.

                                  I want to start a sound, even when the app is minimized. The play action can be initiated from an App Service (Desktop Bridge). My app has the background audio capability and uses extended execution. So the app is not suspended and keeps running in the background. But if I start a sound using MediaPlayer when the app is minimized, the sound does not play. As soon as I open the app, the sound starts. Minimizing again will not affect the sound: it keeps playing.

                                  • 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.

                                    • Make WebView Control usable in UWP console app

                                      Make WebView control or something like it usable in UWP console app. Sometime developers just need to run script to collect the data in the website which doesn't requirement UI.

                                      • 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…

                                        • 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.
