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. Fix Map control so that it is possible to databind/add multiple objects in Universal apps with reasonable performance

    When you add items to the map and then pan the map the items aren't following the map but are lagging behind.

    If you add more than a few, like 25+ the performance is so bad that you have to wait for a few seconds after you stop to be sure that the pins/controls are in the right position.

    This is only happening in Universal apps if we make a Silverlight app the pins are following the map like they should even if more than a few hundred items are added.

    There are lot's of posts about this around the…

    • Add a color picker control

      A color picker control just like the one in the phone's settings would be really useful for apps which want to offer the user a choice of colors. I know I can code one, but it should be one of the standard controls.

      • Allow users with the developer role to create app packages in Visual Studio

        It's great that the Dev Center now allows multiple users to access the same account, and I can submit app packages as a user with the developer role: https://msdn.microsoft.com/library/windows/apps/mt489008.aspx.

        However, it would be even better if it allowed users with the developer role to create app packages in Visual Studio. At the moment, it is impractical for me as a developer to keep asking my boss for his Microsoft account just to create app packages.

        • F# support in .Net native for UWP

          There has been some discussion on the blog post http://blogs.msdn.com/b/dotnet/archive/2015/07/30/universal-windows-apps-in-net.aspx?PageIndex=2#comments for supporting F# in the .Net native toolchain for UWP. I had posted this on the VS uservoice site https://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/7542181-add-f-support-for-net-native but it looks like that was the wrong place to do that. I hope the votes that request got will be considered for this. A lot of people are moving to F# PCLs for library code and to be able to use those PCLs in the UWP and get native compilation via .Net native tools would be great.

            F# team just posted an update on their GitHub. https://github.com/Microsoft/visualfsharp/issues/1096

            This is still a work in progress. One key thing from that post is some of these features and fixes have already been underway for months. While we’ve been investigating F#-specific issues in .NET Native, the team has continued to improve .NET Native. One feature known as “universal shared generics” is likely to have improved .NET Native’s support for F#, even without that being an explicit goal of the feature.

          • 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 …

            • Make PrintHelper support page breaks

              Currently, page breaks are not supported with the PrintHelper. Could this be made possible in a future update? I'd like to print a long MarkdownTextBlock or at least TextBox that does not fit on just one page.

                • Failing to start isolated environment

                  [msft]
                  Right now creating an isolated environment fails for some installers. if you see “E_STARTING_ISOLATED_ENV_FAILED” or “800705B4”, chances are it is this. If you feel it isn’t, please create a new issue.

                  • 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…

                    • ucrtbase bug: _wspawnve is broken

                      There is a serious bug in CRT (ucrtbase) which is part of Windows 10.
                      The long story (please read it, since it contains all information about this bug): https://youtrack.jetbrains.com/issue/PY-17069#comment=27-1803709

                      The short story:
                      _wspawnve is broken when launched from Explorer (not cmd) because ``cenvarg.cpp`` expects undocumented environment variable ``=C`` (covered here: https://blogs.msdn.microsoft.com/oldnewthing/20100506-00/?p=14133) and this variable is not provided by Explorer.

                      Tool to reproduce.

                      ```
                      #include<process.h>
                      // Works from cmd.exe, but not from Explorer on Win10 :)
                      void main() {
                      const wchar_t* const args[] = {L"c:\\windows\\system32\\cmd.exe", L"/?", NULL};
                      const wchar_t* const envs[] = { L"FOO=BAR", NULL};
                      int r;

                        • Make UTF-8 an option for "non-Unicode" programs (ACP)

                          While I personally appreciate Microsoft's recent improvements involving CP_UTF8 in UoW/conhost, I feel that the support is still far from complete.

                          Windows' traditional way of making console programs support Unicode characters – compiler-level settings like TCHAR & UNICODE – have been causing troubles for cross-platform libraries and their users. On the other hand, UTF-8, an ASCII-compatible MBCS with support for full Unicode ranges, has become the choice of "legacy-style" C/C++ programmers as well as front-end engineers.

                          MS is now extending its sphere of influence to many other fields, by introducing open-source programming components and by providing decent cross-platform app-building support.…

                            Thanks for the suggestion.

                            The biggest overhaul to the Console’s innards in more than 30 years is currently underway. UTF-8 support is something that we are and will be working on in order to support a much broader set of scenarios, platforms, clients and tools.

                            Just one example of the level of improvements being made include all the Virtual Terminal sequence support added to the Console during Win10AU to support many *NIX tools, along with the new 24-bit color support we released in today’s Insiders build #14931.

                            Stay tuned for lots more improvements coming in future insiders and major releases.

                          • Please provide support for S/MIME email

                            S/MIME email is a mandatory requirement at my company and support for that on the Windows Phone platform is needed before we can consider it.

                              Thank you for the suggestion and commentary; I’m pleased to mark this suggestion as ‘Started’.

                              As announced at the Microsoft Worldwide Partner Conference and on the Windows Phone Blog, S/MIME support is coming to Windows Phone with the Windows Phone enterprise feature pack, with an announced delivery in the first half of 2014.

                              For more information, please refer to the Windows Phone team blog at:

                            • Enable Manipulation Events for WebView.

                              Since WebView lacks support for Manipulation Events, it acts as a huge gesture eater which doesn't let its parent controls like ScrollViewer, FlipView to take control of gesture like scroll, swipe etc.
                              It becomes impossible to use a WebView along with other XAML Elements in the same view.
                              Manipulation events can help a lot in these situations.

                              • I have developed a custom AppBarButton with a number badge

                                I have developed a custom control: a AppBarButton with a number badge. Could I pull request to the UWP Control Toolkit?
                                Sometimes I need to show a number on the normal AppBarButton to indicate the count of the new messages. I have completed it.

                                • Windows Device Portal Certificate

                                  System is deleting and recreating the TLS self-signed certificates for the device portal on port 50443 a lot.. sometimes every 5-10 minutes in the windows log. For sure it resets them every reboot.

                                    Yup, that’s way too noisy – looks like we’re recreating every single certificate on every single network change, even when most of the network endpoints remain the same. We’re looking at ways to make that quieter. Thank you!

                                      • Devcenter App

                                        Well I think that the devcenter app should be updated/extended so that the app can show the windows store apps as well as the phone apps (which it currently does) Ideally it should also use the live tiles to show the current stats on your apps. And if possible add the ability to connect to the pubcenter as well, or make a 2nd app to handle that. Although I do like the idea of being able to see both the download, and advertising stats for an app at once/one screen or easily go between the two.

                                        • Let an app know if it's pinned

                                          At the moment there's no way for an app to know if its primary live tile is visible or not. As half the point of my app is the information on the live tile, I'd like to have a polite reminder show every so often if they haven't pinned it, but I simply don't know whether they have or not.
