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. GATT Server API

    Provide a GATT Server funtionality over BLE connection (just like Android >= 4.3) so that devices that work as GATT client can be used with WindowsPhone. For now WindowsPhone 8.1 only provides GATT client.

      The Bluetooth team is hard at work adding GATT Server APIs to Windows and we expect GATT Server should be in the Windows Insider Preview builds and SDK later this year. When APIs get added in to the OS and SDK, any developer can start updating their app. Once the next release of Windows is available, any app that want to use these new features will be able submit an update to the Store.

    • 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.

      • 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.

        • Exclude suspending in desktop

          Some apps can work intensively in background, for example it maybe video converting, online financial data processing and more.
          Now UWP application will suspended when it go offscreen.

          I offer to disable suspending in desktop/tablets for user selection (he can choose 'best performance' or 'power saving' options for example)

          • Updated Portal - No longer works

            Seems there was an update over the weekend on my machine (Fast Ring) and now I can no longer upload anything to my phone. The new interface simply doesn't work. All panels are blank.

              • 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 implement the HttpListener class so that we can run REST based controls (similar to Xbox Smartglass) for our own apps?

                    • 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.

                        I modified the Package.appmanifest like shown in msdn.microsoft.com/en-us/library/windows/apps/mt711589.aspx. Basically just copied the lines from the page into it.

                        At compilation:
                        In Package.appxmanifest the line <desktop:Extensions> and <rescap:Capability...> gives warnings.
                        In AppxManifest.xml <desktop:Extensions> produces this Validation error.

                          Please write new documentation how implement VOIP app in UWP. You have only sample on GitHub, but it's not enough. You don't implement sockets, the app is useless, when I suspend/terminate it. I can simulate call only if app is running.

                              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:

                              Now with Win10 Dashboard the stack trace only provide a snippet of the error which is included in the error lines. However with the new dashboard this is the only information that is provided on the dashboard. It's not enough for devs :(

                                • 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…

                                  • Decouple Appium service from app process

                                    Today if I want to relaunch the app, it requires killing & restarting WinAppDriver which implicitly launches the target - not only is this at odds with Appium but it creates an uncomfortable dependency between the test code and execution environment that isn't desirable in CI and other "real-world" test situations.

                                    • [Bug] Resources broken in a DataTemplate with 14393

                                      Using Resources in a DataTemplate worked just fine before.
                                      Now that I've upgraded to Anniversary and installed the newest SDK and Tools + the newest Visual Studio Update it doesn't work as expected at all.

                                      If I have a datatemplate like this:

                                      <DataTemplate x:Key="SomeDataTypeItemTemplate" x:DataType="data:Type">
                                      <Grid>
                                      <Grid.Resources>
                                      <vm:ViewModel x:Key="MyViewModel" Item="{x:Bind}"/>
                                      </Grid.Resources>
                                      <TextBlock Text="SomeText" Visibility="{Binding IsVisible, Converter={StaticResource VisibleWhenTrueConverter}, Source={StaticResource MyViewModel}">
                                      </Grid>
                                      </DataTemplate>

                                      This will crash on instantiation because somehow the ViewModel object is null when the Bindings are updated which was definitely not the case in previous versions and surely not the expected behavior.

                                      If I replace the x:Bind with a…

                                      • [Bug] UWP CollectionViewSource in DataTemplate in ResourceDictionary binding breaks

                                        - Take a CollectionViewSource in a DataTemplate in a ResourceDictionary
                                        - Use that DataTemplate in a page
                                        - Navigate to another instance of the same or another page also using the DataTemplate
                                        - The CollectionViewSource remains bound to the first page's collection
                                        - Navigating to other intermediate pages doesn't affect the result.

                                        See https://github.com/ehaskins/UWP-Bug-Reproduction for reproduction.

                                          Hi,
