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. 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…

      Thanks for the continued feedback in this area. We’re exploring ways to enable this easier in the platform than existing alternatives. SVG has a lot of facets to it and we want to ensure we are hitting the right scenarios without sacrificing platform integrity and performance.

    • ToUpper property on TextBox

      Please create this option native to TextBox control
      It's very usefull in WinForm projects and could speed up development on universal app too.

      • MaskedTextBox Control

        The TextBox control is the most used control in a Windows program. It also cause a lot of problem either from QA or the user because of invalid data that was entered. Using a masked control will save a lot of time for the developer and reduce the complaints and bugs

        • 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 …

          • Replace Xamarin.Forms Xaml syntax with latest UWP Xaml

            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)

              This is great feedback. We are excited about the Xamarin acquisition and the .NET ecosystem around cross-platform apps. We are currently looking at this and similar feedback on how we can improve the experience of working with both Xamarin.Forms and UWP implementations of XAML.

            • 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…

              • ScrollViewer overpan API

                Currently when you overpan a ScrollViewer, where's no way to tell how much negative offset it is unless you do hacks like calculating it every 50ms via a Timer.

                This will make interesting actions like 'Pull to Refresh' very hard to implement.

                Would be nice to have an event to listen to this with a OverpanOffset property or something.

                • PasswordBox with Number only keyboard

                  it would be helpfull to have a passwordBox like control which supports Number only keyboard. Numeric only passwords makes more sense for Smartphone world as its fast, convenient and easy to type.

                  • 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.

                      Right now we can't show progress on the taskbar for example to let a user see the current status of a download or something else. Media player buttons are possible in the taskbar but why not the progressbar?

                      • 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.

                            I request that the MultiScaleImage library to be able to access isolated storage. There are many places where apps will not connect to a cell tower [e.g. in a general aviation (or commercial) aircraft where cell phones do not work well [it is illegal to use in any case] and also in isolated rural areas. Also, why pay data charges to view the same image over and over [aren’t music & photo libraries stored on phones?] And finally memory is very cheap. Some suggest that large images (even broken into tiles) are inappropriate for storage on a phone – that…

                            • Improve WinRT Frame caching and navigation behavior

                              Windows Runtime API has presented Frame class, which page caching and navigation logic differs from a corresponding Frame class from Windows Phone Silverlight API set. This new Frame class gives a lot of pain to developers, because in many cases it cannot provide such app and navigation state management, which can be used to create good and predictable user expirience. Therefore, I want to request adding of some improvements in WinRT API to bring Frame's behavior closer to it's analog from WP Silverlight.

                                    • [Request] Allow base application container to be see-through/transparent

                                      In other words, I want to be able to create designs such as this: http://i.imgur.com/27fUxtM.jpg (notice the left side of the application, where there is transparency and part of the desktop (which is immediately behind the application) can be seen through).

                                      Providing more design options, allows us to diversify our application's interface designs and…

                                      • Make tapping top of lists scroll to top

                                        Follow touch enablement of mobile platforms and enable the list controls by default to have a "tap top" area that scrolls to top of list automatically.
