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?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

  1. Support SVG elements in XAML

    The high-level ask is to support using SVG within a XAML tree. The SVG data may be inline or loaded from a source (local file or remote from the web)

    There are few current tools for converting SVG to WPF/Silverlight-based XAML but they fall short when dealing with more complex SVG data.

    Here are a few scenarios:

    - Apps loading svg content from a remote web server. This should work just like any other kind of image data. Remote xaml isn’t likely allowed, and even if it were, there’d be resistance to providing vector art in two formats when SVG…

    • Enable Blur and Transparency XAML Effects to Allow for Creative see-through UI designs

      The new start menu features the Aero (transparency and blur) effects we all love. It'll be great if we can enhance our own apps with the same effect where we choose. In addition to transparency and blur on any control, give us the ability to apply the effect to the base container, thus making portions of our application see-through to the desktop.

      In other words, I want to be able to create designs such as this: http://i.imgur.com/27fUxtM.jpg

      Providing more design options, allows us to diversify our application's interface designs and set it apart from others in the market.

        This has two parts, one being blur, second is allowing blur to see through to the desktop / have custom layout design.

        Right now, Blur will be added in Composition in upcoming SDK release shortly.

      • Add Markup Extensions to (and Improve) WinRT Xaml System (System.Xaml Parity)

        Much effort was made in WPF Xaml Serialization to decouple it from the presentation assemblies and moved into its own assemblies, System.Xaml, and System.Windows.Markup.

        This Xaml System had it's own serialization/deserialization mechanism in XamlServices class. Furthermore, this Xaml system had a very powerful component/concept that is conspicuously absent in WinRT: Markup Extensions.

        Markup Extensions are found in the following Xaml Systems:
        - WPF
        - Silverlight 5
        - Xamarin.Forms (notably NOT a Microsoft technology, but recognizes their power nonetheless)

        This feature is to ask for Xaml serialization featureset parity with WPF/System.Xaml. That means:
        - Custom Markup Extensions
        - XamlServices.Load and Save …

        • Add support for 'XmlnsDefinitionAttribute'

          XmlnsDefinitionAttribute is an absolutely great attribute for Control Library developers. It allows the developers of that control library to greatly simplify the xaml by reducing the number of XMLNS declarations they need.
          The only way around this is for the control vendor to throw every single class that might be used in XAML (not just controls but other types too), in the same namespace, creating a very ugly unwieldy API to code against.

          If you use a 3rd party control library or you're a control library vendor, you should vote for this. It'll save you a lot of typing, looking…

          • Set break/trace-points in XAML x:Bind to have it set in code-gen

            When debugging XAML apps, it should be possible to set a breakpoint or tracepoint on an x:Bind and have the debugger stop on the code-gen binding.

            The generated bindings code is very large and not easy to follow. Further, it doesn't even exist until compilation and even then isn't visible to the user in VS.

            The idea here is to set a breakpoint or tracepoint in XAML and have VS break on the appropriate code-gen method instead.

            • Ancestor binding missing

              Currently the RelativeSourceMode only supports None, TemplatedParent and Self.

              Would be really helpful to have FindAncestor API added, just like in Silverlight 5 and WPF.

              • Enable text effects in Windows Runtime XAML apps (border shadow, etc)

                XAML apps need the ability to create text effects on the TextBlock and other text elements. This is a standard feature for other platforms. On Android you place it directly in the markup*. This feature was planned for WP7 but was removed for RTM**. It's been over four years since that post from Shawn Oster, it's time to get this into the platform.

                Text effects are not just for fancy/weird text. It is needed when displaying text on pictures. If your font foreground in white and there are white elements in the picture the text gets lost. Providing an overlay…

                • UWP Windows Always On Top

                  Allow an API to cause the window to be always on top. This is great when watching a video while other apps are in full screen. It'll be like Picture in picture (PIP).
                  Another use case for this would media player controls so that they are always visible. Also, an application like ColorPic.

                  • Get currently playing song information

                    Within Windows Phone 8.0 it was possible to use the Microsoft.Xna.Framework.Media.MediaPlayer to get information (song, album, artist name) about the currently playing songs. WP 8.1, RT and Universal don't provide a way to read this information, I can only write them using the SystemMediaTransportControls.

                    Pleas bring back the capability to read this information.

                    • Implement System.ComponentModel.TypeConverter in WinRT APIs

                      TypeConverter is helpful because it allows the author of a type to provide intrinsic support for determining to/from which types a type may be converted and actually converting between types - most typically for converting to/from string but other types as well.

                      • Multibinding support

                        Binding to more than one property is essential in many situations. The fact that it wasn't included in the first version is pathetic. And no, using a parameter is not sufficient.

                          Now that Microsoft has bought Xamarin, integrated it in Visual Studio and made it free, it would be awesome to replace Xamarin.Forms Xaml syntax with current UWP so that Devs can benefit from all the new rich features such as RelativePanel, x:Bind, Adaptive Triggers, Live Visual Tree etc and also no learning curve for Xamarin.Forms-specific naming conventions (e.g StackLayout instead of StackPanel)

                                • Allow On/Off button for any app to be placed into Action Center

                                  Although the Action center quick settings are really useful, it's still quite limited - no option to toggle Mobile data or force Battery Saver.

                                  It would be ideal to allow ANY developer to place his app On/Off button inside this Action Center, for instance:
                                  - enable/disable Fitbit tracking
                                  - turn lights on/off at home via light controlling app
                                  - Start Xbox One remotely via Smartglass app
                                  - and much more, the possibilities are endless!

                                  Ideally it should be as powerful as Secondary tiles.

                                  • Device status in Windows Runtime App

                                    Provide API's to retrieve the current device information(OS info, RAM size, power source) in Windows Runtime App.

                                    The equivalent class in Windows Phone 8 is Microsoft.Phone.Info.DeviceStatus

                                    • Sortable Observable Collection

                                      Currently for dynamic data binding controlls like listbox, <a href="http://msdn.microsoft.com/en-us/library/ms668604%28v=vs.95%29.aspx">ObservableCollection</a> is recommended. However the collection does not implement Sort, and it does even implement Move (so you can implement sorting on your own by extending it). Can we have a sortable observable collection for WP7?

                                      • Contact Manager api : Need performance optimization

                                        I am developing a Windows Phone 8.1 application using windows xaml and c#. And the app needed to sync users phone contacts with the server.

                                        So at the point , We need to get all contacts from the phone and have to send it to the server. But compared to Silver light version contact api performance is really poor and it takes mare time to load all contacts.

                                        Please consider my suggestion on this case

                                        1. Polish your new Contact Manager api to get the maximum performance .Hence the user not to sit idle till it loads.

                                        2. I could…

                                        • keyboard color options for a consistent and unique experience throughout the app.

                                          Please provide the ability to the developer to change the color of the keyboard inside their app. This will help us developers make more beautiful, consistent and unique looking apps.
