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. 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.

      A change was made in the Windows core platform where the feedback hub with app context count not launch from a non-UI thread, sadly, the engagement SDK was not updated to support this change. We have updated the SDK to call the launch of the feedback hub from calling thread, we have tested extensively to ensure that it works in the most common scenarios and have updated the SDK (both the MSI and the NuGet) to support this change. If your application is in the Microsoft Store, the application was updated automatically to your end users.

    • Make UWP great again with RDP client

      RDP integration with UWP is a very important missing API that we had in FORMS and WPF, can you please make a new one that we can use in our internal Apps so we can migrate existing old Form apps to UWP and Windows 10?

      • Full-Trust UWP Desktop Applications

        Look, the concept of "UWP apps can run on your phone (RIP) and your Xbox," while admirable, isn't practical for most applications. Many applications need only Desktop support. UWP is too "safe" so as to be impractical for so many desktop apps, and WPF is like a third-class citizen with Microsoft in the background cheering "Upgrade to UWP!"

        The sandbox nonsense has to go. Allow UWP applications to tick a box in the .appxmanifest declaring it as a full-trust desktop application. Prevent full-trust apps from targeting phone and Xbox if you have to. Show a notice to users upon install…

        • MediaStreamSource: Add way to use IMFGetService from downstream Pins

          Currently, it is not possible to implement hardware acceleration in MediaStreamSource. For that, we would need to get a d3d device manager from the downstream Pin.

          If we could call GetService, e.g. on the MediaStreamSourceSampleRequestedEventArgs or in a new "Connected" event, then it would be possible to implement d3d based hardware acceleration in MSS. This would be very useful e.g. for the FFmpegInterop project.

          • Need (improved) Alarm & Reminder APIs in WP8.1 RunTime for creating Universal apps

            There's currently no way to create a universal app that has alarm/reminder functionality because these APIs are not included in the new WP RunTime.

            Also, the existing Alarm & Reminder APIs for WP8 are very limited. When they eventually get added into the new RunTime, can you guys please consider the following possible improvements?

            1. Able to select a song from Music Library as the alarm/reminder tone.
            2. Allow custom snooze time.
            3. Vibrate only support.
            4. Allow customizing the Alarm/Reminder popup.

            I raised a request on the uservoice site over a year and a half ago, it's got 15k…

              We’ll send you updates on this idea

              This topic contains a few things, we feel there are ways to do this now (listed below) and work arounds. If there are targeted APIs you are looking for, please create a single UV item for each one as this allows us to close items out.

              What has been done:
              1. There is now a way to create an alarm/reminder in universal windows apps;
              2. The alarm/reminder supports custom snooze time (you can choose to let system handle snooze, or wake up your background task to do it manually);
              3. The alarm/reminder supports vibrate only (just like toast) that can be overwritten by user to turn off vibration;
              4. The alarm/reminder supports a good level of customizability (custom optional inline image, custom additional actions, etc)
              There are several blog post that describes above capabilities with more details:
              http://blogs.msdn.com/b/tiles_and_toasts/archive/2015/07/02/adaptive-and-interactive-toast-notifications-for-windows-10.aspx
              http://blogs.msdn.com/b/tiles_and_toasts/archive/2015/07/08/toast-notification-and-action-center-overview-for-windows-10.aspx

              What we know that’s missing and hope to support in…

            • HttpClient: Allow inspection of server certificate during SSL handshake

              Right now, we can only inspect the server certificate after a request was done, by using 'RequestMessage.TransportInformation'.

              Because of this, it is not possible to have a decent implementation of SSL pinning using the HttpClient (or any other method without rebuilding the entire networking stack), The request should not actually take place if the certificate validation fails.

              It is possible to install allowed certificates through the Package.appxmanifest file and then checking Exclusive trust. But unfortunately, this is application wide, and so all certificates of all services of websites that might be called in the app must be included.

              • Selectable TextBlock

                We need a TextBlock property that makes it so you can select text. Often, making a TextBox read-only is not sufficient because the TextBox doesn't have the same formatting capabilities as the TextBlock.

                  • [UWP] ScrollViewer layout cycle bug

                    There is quite a bad bug in the UWP ScrollViewer control that causes a layout cycle exception to be thrown. It occurs under these conditions.
                    1. The ScrollViewer contains a panel like a Grid with VerticalAlignment set to stretch (the default).
                    2. The ScrollViewer height changes when the window resizes (or for some other reason).
                    3. The ScrollViewer height is less than the height of the content of the panel, and the vertical scrollbar is showing (e.g. hover over it with the mouse).
                    4. The window is resized with the scrollbar still showing so that the ScrollViewer height is greater…

                          In Windows 10, we introduced new APIs to simplify data sharing between apps. Now, as an app publisher you can configure your apps to share some data using ApplicationData.GetPublisherCacheFolder folder – https://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.applicationdata.getpublishercachefolder.aspx

                          Also, with help of SharedStorageAccessManager, your app is able to share a file with another app by passing a token as part of a Uri activation – https://msdn.microsoft.com/library/windows/apps/windows.applicationmodel.datatransfer.sharedstorageaccessmanager.aspx

                        • Doesn't work xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"

                          The xmlns specified in this article about getting restricted capability is not working.

                          Using: <rescap:Capability Name="contacts" /> doesn't resolve. And I still cannot get full access to Contacts on my local PC.

                            The contacts capability provides access to the aggregated view of the contacts from various contacts stores. This capability gives the app limited access (network permitting rules apply) to contacts that were synced from various networks and the local contact store.

                            The contacts capability must include the uap namespace when you declare it in your app’s package manifest as shown below.
                            XML

                            uap:Capability Name=“contacts”

                              It would be nice to have an attached property for ScrollViewer to set middle click scrolling.

                                I'm using the UWP ColorPicker introduced in Windows build 16299. I am having a problem where the color selection cursor can't be dragged around with the mouse cursor. The ColorChanged event is being fired and I'm able to use the results of the event firing, but the ColorPicker cursor just stays in the upper left corner. My project is targeting version 16299.

                                • detect sets status

                                  It would be great if apps can detect whether they are in a set or not. I would like to modify the user interface of the app when the app is in a set/tab. If this is implemented I would like to use it in XAML, like I use AdaptiveTrigger.

                                    • Add WPF UniformGrid to UWP

                                      The WPF UniformGrid (https://msdn.microsoft.com/en-us/library/system.windows.controls.primitives.uniformgrid(v=vs.110).aspx) is missing in UWP. It doesn't seem to quite have an equivalent in UWP in order to get even spacing of a grid automatically, as well as other features like setting rows/columns and first column for calendar type applications.

                                      • Allow alarms to break through Quiet Hours

                                        Hello.
                                        My alarm app which uses alarm-scenario toasts cannot break through Quiet Hours.

                                        I received plenty, I mean really plenty feedback from users desperately wanting alarms to break through Quiet Hours.

                                          We’ll send you updates on this idea

                                          In the Creators Update (build 15063), all third-party alarm apps (toasts using scenario=“alarm”) will break through quiet hours now, just like the first-party alarm app!

                                          Thank you everyone for letting us know that this feature was important to you!

                                        • Allow development of Windows Store apps offline - no license required

                                          When developing Windows Store apps, it appears that you must be connected to the internet in order to obtain a 1 month "developer license".

                                          This seems to me to be an unnecessary hurdle to the development process. My employer has an explicit policy that prevents dev machines being Internet connected.

                                          I understand the license is probably an anti-piracy measure (or some means to stop users deploying apps outside the Store), but seems overly heavy-handed for a development environment.

                                          MS, please don't just assume that all your users are Internet connected, all the time. Can we have this fixed pronto, please.
