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. 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!

      • Add the link for the feedback hub to the store's app review form

        Could you add the link for the feedback hub to the store's app review form? I believe that the 'app review' and 'report for developers' should be divided.
        Because - a lot of user post a bug report to the app review on the Microsoft Store.
        But, In fact, most of these posts should be handled with feedback hub. By using feedback hub, we - app developers - can contact with the users to get know the detail and track the defects.
        Is it possible to add the note to the review form as following?
        "If you have a trouble…

        • Allow x:DefaultBindMode on App Element in App.xaml

          Today we have the x:DefaultBindMode attribute to define the default binding mode generated for a compiled data binding created with x:Bind.

          We can set that mode on an element or on a parent element.

          It would be a huge advantage to support this attribute also on the App-object in the App.xaml-file, and to make this the "ultimate root".

          This would allow me to specify an application wide default binding mode, and I could set it in this single place for example to OneWay.

          • Multiple Instances of UWP Apps

            I have used Unity+UWP to develop LOB application that visualizes 3D data from opened files. We also use multiple-top-level windows that are already available. Now client wants to allow opening and visualizing multiple files, which would have been easy with Win32 (just launch another instance). One of the problems in here is Unity code, which is mostly made to be single-instance, but it would be great to have support to launch multiple instances of the same app.

            • Ability to type when using TimePicker

              It's a pain to use the TimePicker control on desktop. When selecting the minutes, you have to scroll through a huge list of 60 numbers...

              Instead, you should be able to just type "45" to select 45!

              I'm using the time picker in my app, Power Planner, and two users have complained about this (and I've complained about it myself). This should be part of the built-in control! It's quite terrible to use on desktop presently!

              • Make Notepad open-source

                Notepad has been updated to support Line endings from Unix, Linux, and Mac. I think we should take it one step further and make Notepad opensource like Powershell so the open-source community can continue to add features to Notepad to become the go-to text editor for performing quick edits of programming.

                  • 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.

                    • 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.

                      • Webview crash with too long URIs

                        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:
                        https://github.com/jeroen1602/UWPWebviewCrash

                        • CalcBinding for UWP

                          CalcBinding is an advanced Binding markup extension that allows you to write calculated binding expressions in XAML, without custom converters. CalcBinding can automatically perform bool to visibility conversion, inverse your expression and more. CalcBinding makes binding expressions shorter and more user-friendly.

                          This is only available for WPF - https://github.com/Alex141/CalcBinding

                          Here are some examples

                          <Label Content="{c:Binding A+B+C }" />

                          <Label Content="{c:Binding A*0.5+(B.NestedProp1/C - B.NestedProp2 % C) }" />

                          <Button Background="{c:Binding '(A > B ? media:Brushes.LightBlue : media:Brushes.White)'}"/>

                          <TextBox Text="{c:Binding 'Math.Sin(Math.Cos(A))'}"/>

                          <Button Visibility="{c:Binding !IsChecked}" />

                          <c:Binding 'A and B or C' />

                          • 1803 NavigationView built-in back button placement looks terrible.

                            For 1803, I like that the backbutton is now built-in to the NavigationView control. However, the placement of the button looks terrible next to the hamburger button.

                            I was actually excited to see it was built into the Nav control because i can't figure out where to place the backbutton either such that it doesn;t look weird and out of place... but, the built-in nav backbutton doesn't solve the problem either... it still look weird and extreme beta...

                            • [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.

                              • 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…

                                • ISupportIncrementalLoading not called when display scaling set to 125%

                                  I'm using an incremental loading collection in a page.

                                  When (and only when) text scaling is set to 125%, neither HasMoreItems nor LoadMoreItemsAsync are ever called.

                                  The weirdest thing is that it works just fine on 100, 150 and 200%.

                                  • Notify me when new feedback comes to Feedback hub

                                    Currently we have no notifying system to the developers when the customer add new feedback to the feedback hub. We, developers should check the developer dashboard every day and day. It's tooo painful. Is it possible to add the notification system? Just ping by mail is enough. Uservoice already have it.

                                    • 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).

                                      • Text Trimming should support a Position

                                        Sometimes you want text trimming to occur from the left or middle like "...some of my text." or "C:\Long Path...\somefile.txt". The TextBlock TextTrimming property should have an auxiliary TextTrimmingPosition property which defaults to Right, but can also be set to Middle or Left to support the same types of scenarios but in the other locations.

                                        • Include more info in ToastNotificationHistoryChangedTriggerDetail

                                          Ask: At a minimum, add the list of Tag/Group tuples affected by the change. Better still, surface the actual ToastNotification objects in the detail.

                                          Reason: There's currently no API available for tracking the full lifecycle of toast notifications through Action Center. ToastNotificationHistory only provides the current state, which even with polling/diffing doesn't provide the reason a notification was removed (expired? queue too long? user removed?). Meanwhile, the background-task history trigger only provides a general "something changed", not the actual toasts affected.

                                          This makes it extremely difficult for an app to maintain any in-app representation of notifications and synchronizing changed with…
