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. Enable WinAppDriver for Xbox and Mobile

    Right now WinAppDriver only works on desktop.

    Getting these capabilities across the Windows ecosystem would fulfill the promise of a unified Windows. Making it possible for us to write tests, and code once and have it being tested in an autonomous way. So that in theory, our applications could report and find bugs for us.

    Before our users find them.

    Thanks in advance. Looking forward to the progress you're doing :D

    • Using x:Bind or Binding in a Setter Value property of a VisualState

      Using x:Bind or Binding in a Setter Value property of a VisualState will not be executed at the start of the view, you have to change the state of the and then go back before the bindings are used resulting in initial views being broken.

          • Nullable dependency properties

            Should be clear, nullable properties in XAML should be supported and not give the error "Cannot assign to nullable type on property".
            This is really way too long in UWP Xaml not addressed.

            public static readonly DependencyProperty IsTestProperty = DependencyProperty.Register(nameof(IsTest),typeof(bool?),typeof(ControlY, null);

            public bool? IsTest
            {
            get { return (bool?)GetValue(IsTestProperty); }
            set { SetValue(IsTestProperty, value); }
            }

            <uc:ControlY IsTest="true" />

            • UI Access support for Centennial Converter

              We have a uwp in the store and a desktop companion app. Currently to install our software (and have it function) both programs are needed. Merging them into a single installer would benefit our users greatly. It seems in order to do that we need to either pull out of the store or convert our desktop app to a uwp and merge the two installers. The issue we run into is that our desktop app uses ui access. Is ui access support on the list of upcoming features? Having a good informed answer to this question will help tremendously in helping us understand how…

              • Allow context menu verbs with file explorer integration without having a file type association

                On this page, there is explanation how to make a file explorer integration on a desktop bridge app:
                https://msdn.microsoft.com/sv-se/windows/uwp/porting/desktop-to-uwp-extensions

                In short you could add something like this in your manifest-file:

                <uap3:Extension Category="windows.fileTypeAssociation">
                <uap3:FileTypeAssociation Name="MyApp">
                <uap:SupportedFileTypes>
                <uap:FileType MultiSelectModel="Document">.txt</uap:FileType>
                <uap:FileType>.foo</uap:FileType>
                </uap:SupportedFileTypes>
                <uap2:SupportedVerbs>
                <uap3:Verb Id="Edit" Parameters="/e &quot;%1&quot;">Edit</uap3:Verb>
                <uap3:Verb Id="Print" Parameters="/p &quot;%1&quot;">Print</uap3:Verb>
                </uap2:SupportedVerbs>
                <uap:Logo>Assets\MyExtensionLogo.png</uap:Logo>
                </uap3:FileTypeAssociation>
                </uap3:Extension>

                I’m working on porting an app that could calculate MD5 checksums on a file. I want to add this as a context menu option on for instance zip and iso-files. But it’s not possible to do this without making a file type association as I get it :(.…

                • Compiler Warnings vs Errors

                  In VS2015 (and maybe in 2017) the compiler raised a warning (that we missed) that stated some of our code was "currently unsupported" by the UWP toolchain. This led to a runtime crash that took a long time to figure out. To me, something that may cause a runtime crash (and that the compiler clearly "knows" to flag) should not a warning but an error. The specific issue was:

                  warning : SG0002 : Cannot generate serialization code for type '***'
                  The 'MethodName' property of the KnownTypeAttribute on type 'ObjectModel.Entities.BaseThing' is not currently supported. See http://go.microsoft.com/fwlink/?LinkId=723954 for more information. (TaskId:267)

                  • Add an ExpirationTime property to the ScheduledToastNotification

                    The ToastNotification object has a convenient ExpirationTime property that automatically dismisses it after a given period. Unfortunately, the ScheduledToastNotification, which is just a ToastNotofcation but "scheduled", lacks this helping feature. This makes me, as a developer, scracth my head and write a lot of code including background tasks just so I circumvent this problem and not have the users of my app get crowded with not-so-relevant-anymore notifications in their action center.
                    Thank you.

                    • Specify Arguments in AppxManifest.xml for Application Executable

                      Many developer will be bringing java / python / etc applications to the Windows Store via the Desktop Bridge.

                      It would be great if the <Application Executable="launcher.exe"> element or the <uap3:Extension Category="windows.appExecutionAlias"> element would allow me to specify arguments in the AppxManifest.xml file.

                      That would allow me to use the bundled javaw.exe or python.exe directly and instead of having to use my own launcher that effectively does nothing but call javaw.exe / python.exe with some predefined arguments.

                      • Custom audio in toast message bug

                        Currently, UWP app has to be installed in device memory in order to use custom audio file in toast notification. In case app is installed in SD card and notification uses custom audio file, default notification sound is played instead of custom audio file.

                          Thanks for posting this bug here Viktor! Our devs investigated this bug, but we unfortunately won’t be able to fix it for the upcoming Creators Update. However, we will look at fixing it for the subsequent release!

                          If your app is also affected by this, please vote and also leave a comment telling us what your app is!

                          • Add an option to 'Create dump file' of running process

                            Currently there is no way to attach debugger to already running process via 'Attach to process' on mobile. And sometimes bad bugs, like deadlocks, happens. And its real pain to investigate them, since usually they happen without debugger and on release builds. Windows 10 Mobile is like back box you can't get full access to.

                            In addition to existing functionality which allows to collect dump when app crashes, it would be nice to have an option to collect dump of running process on Windows 10 Mobile any time you want via device portal.

                            Thanks.

                              Great idea, makes sense. We’re looking at enabling live dump collection of processes that belong to sideloaded apps, so that you can collect information about app state if it hangs. If that’s insufficient, please let us know. Thanks for your input!

                                  UWP platform lack classic console application model.
                                  Why it's important? First example when it would be useful are unit tests that can be started on build server, powershell script or some other automatic tool. Console app model is a natural way to handle things in many use cases. What is most important, these console UWP apps would be built for and run on UWP platform and so it would be a perfect for testing or automation purposes if UWP platform is exactly needed. For mobile devices it would be perfect to use "remote console" feature, so desktop development environment would…

                                  • [Bug] AudioGraph: Gaps and clicks during playback

                                    To reproduce you may start with official AudioCreation sample from https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/AudioCreation/cs/AudioCreation
                                    Use file playback sample or custom effects sample. Depending on hardware, you may hear gaps right after start or you may need load CPU with some additional work, like scrolling UI or running some work in background threads.
                                    I guess it is result of extremely short quantum size (10ms; even switching between threads could take more time) and too low buffer length (2 quants), but it could be just some synchronization issue.

                                    • The installed Centennial executable does not know about its installed folders and cannot find them.

                                      For example, if in the msi/ appx is added folder, like Samples or Projects, it cannot be found by the open/ save dialogs, with set "Initial Directory", opened by the installed executable, even if the folder is installed in the installed executable's folder. Actually, initially I constructed the msi by placing the folder in the Documents folder, but the Centennial does not install it there, but in the VFS\.... It will be hard for the user to find these kind of folders too.

                                      • WinAppDriver: Ability to run application with arguments

                                        It would be great to have an ability to run application with arguments using WinAppDriver. For example, run installer from MSI package:
                                        dc.SetCapability("app", @"C:\windows\system32\msiexec.exe");
                                        dc.SetCapability("args", @"/i C:\installer.msi");

                                        Currently it is possible to do it using Winium, but not possible to do using WinAppDriver.

                                        • Include more info in UserNotificationChangedTrigger

                                          Add a UserNotificationChangedTriggerDetails to UserNotificationChangedTrigger background task with at least:
                                          1. Notification ID
                                          2. Event type (Added, Changed, Removed, etc...)

                                            Hey! We’re aware that right now, there’s no out-of-the-box way to determine the changes that occurred with UserNotificationListener.

                                            The correct solution is for us to build a ChangeTracker, similar to the ContactChangeTracker, FileChangeTracker, etc, since you cannot trust that the background task is actually handled. A ChangeTracker ensures 100% reliability.

                                            We would like to build a change tracker for UserNotificationListener, but are not sure when we will build this. In the meantime, you can easily determine the delta of changes yourself, and we have sample code on the documentation illustrating how to do this (under the “Determining which notifications were added and removed” section) https://blogs.msdn.microsoft.com/tiles_and_toasts/2016/05/26/notification-listener-documentation-windows-10/

                                            Thanks!
