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.

      Currently, the platform provides a number of SMS Access from a system eventing perspective (as of Windows Phone 8.1), and Windows Phone supports sms backup/restore for consumers as part of the base OS (Settings → Backup). What we don’t provide is a backup API.

      Using SMS events: Check out the Build 2014 session (http://channel9.msdn.com/Events/Build/2014/2-518) or MSDN docs on background tasks (http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh977056.aspx)

      Although the capabilities are there from a consumer perspective (the core ask for the suggestion), I’m marking this as ‘Under Review’ for the API perspective. The team is aware of the ask and it is something that is being considered.

    • API to Get/Set Volume and vibration settings

      Currently, when developing a alarm clock app, there is no way to tell if the user has his phone set to vibrate only, so a soundeffect set by the user is played even if he has set his phone to vibrate. I find this very confusing, even though the builtin alarm clock behaves the same way.
      This would also be good to have for games, so when you launch a game in a quiet environment not all heads turn the user's way :)

      • Allow alarms to break through Quiet Hours

        Hello.
        My alarm app which uses alarm-scenario toasts cannot break through Quiet Hours.

        I received plenty, I mean really plenty feedback from users desperately wanting alarms to break through Quiet Hours.

          In the future, we’ll look at enabling this! It’s definitely important that third party apps can do the same as first party apps (like how the first party alarm app can break through quiet hours).

          Thanks for all the votes! If you also need this feature for your app, let us know by voting!

              We appreciate the interest in Windows 10 and we’re looking into what’s possible. Currently, we don’t have immediate infrastructure to support Iranian developers but we’re investigating solutions.

            • API to control screen brightness

              I would like to develop a bedside alarm clock app where the user can control the brightness by touch - so the app can run with the screen off unless the user is touching the screen, or the user can pinch to make the display lighter or darker. All I am able to control at the moment is the contrast of the display (by playing with the colours and alpha levels of the rendered graphics).

              • 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.

                • Show a paid app w/ a "trial" option in the "free apps" category

                  When I create a paid app with a trial option, many users blow right by it because it doesn't show up in the "free" category even though a light version of the app is free (via the trial).

                  Some people are resorting to the super-inefficient Apple app store method of releasing 2 versions of the app... one that shows up in the "free" category and another that runs as a paid app. The "trial" is a fantastic concept, but it is hobbled by this oversight

                  • Make Universal Windows Platform Open Source and Cross-Platform

                    With the advent of //build 2015, the vision and direction of Microsoft seems to be open source and cross platform. This appears to be the case for every new product from Microsoft except for the Universal Windows Platform.

                    It would be great, ideal, and wonderfully awesome to see this platform reach consistency with the rest of the organization and embrace the ideals, values, and benefits from being open source and cross platform like other areas of Microsoft now are (or are on their way to being).

                    Please provide consistency throughout the entire Microsoft development ecosystem!

                    • API for Direct phone interaction [dialing, sending/answering, replying/recording, playing to, hooking up/filtering Phone call]

                      Without these APIs, PC and Phone are losing features event had existed in pre-internet age and becoming backward.

                      When a feature is useful and eases user's pain of doing monotone taping, the security excuse seems a red herring; you can always find a way to do it and there were/are devices could/can do it, why not the Windows Phone, because Apple doesn’t do it?

                        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.

                          Kiran works on the team.

                          We published this video for //Build2016 this year – https://channel9.msdn.com/Events/Build/2016/P460

                          In it, Kiran talk about how we plan to make unpaired BLE interaction available later this year. GATT Server APIs will be available to developers in that update so please stay tuned! I’ll reply back on this thread when it’s ready but suffice to say we’re hard at working making this happen. Thanks again for your support!

                        • XAML for live tiles

                          Allow developers to implement an interface(s) on a user control and "submit" that instead of just filling in a tile data structure. This will make tiles truly "live" and open up the live of WP7 to new applications. This is also completely secure because the runtime can analyze the class (and it's IL) being submitted. A bevy of restrictions can also be heaped on the said user control in order to maintain performance and not sap battery life. Let Live tiles be live, please.

                            It’s great to see that XAML for Live Tiles is so highly requested!

                            In Windows 10, we created Adaptive Tile Notifications, which partially addresses this issue. Adaptive is a lightweight XML way to define your tile notification’s appearance. It isn’t as powerful as XAML, and it isn’t animated, but it’s a step in the right direction. The MSN Weather app uses Adaptive to create their rich and beautiful live tile.

                            Learn more about Adaptive here: http://blogs.msdn.com/b/tiles_and_toasts/archive/2015/06/30/adaptive-tile-templates-schema-and-documentation.aspx

                            In the future, we’ll definitely look at how we can make Live Tiles even better, potentially by supporting XAML. There are performance and other implementation issues, but we definitely understand the need for it.

                            Thanks!

                            Unlike Windows 8.x/RT, Windows Phone does not permit third-party apps to download in the background, at least to the same extent as first party apps, e.g. the WP App Store. Please enable the necessary APIs that could allow developers to permit background downloading, a number of WP apps could serve to benefit greatly (e.g. Torrex, wpTorrent, PODCASTS, etc). It will also clearly position WP as a strong contender against rival OS in the sense that it would operate like a powerful platform.

                            • Throttle emulator to hardware specs of phone CPU + GPU

                              Create an option to simulate hardware specs like CPU+GPU.
                              Dual-core, quad-core, 1.2GHz, 1.5GHz, 2.2GHz, ...
                              The emulator is very very fast when I'm using it on my i7 4770. It would be good if we can at least optionally reduce the speed of the emulator to better reproduce real world devices.

                              • Emulate Bad Data Connection - v2.0

                                I suggest to create another option that alternates "lost of signal" and "bad signal". Create an infinite loop that breakes the connection in a random time. From 1 to 10 sec, for example.

                                A an ability to the emulator that can emulate a bad data connection so we can discover performance problems before our clients receive it. Things like throttling and dropouts

                                The new emulators in the Windows Phone 8.1 tooling provide some excellent tools for emulating bad network connections, but there is no option to simulate broken connections

                                • Provide fix for c101a7d1 when updating, 80004005 when installing, license reset on reinstall

                                  Microsoft Support recommended me to post the issue here. There seems to be a long-standing serious issue with the Store (or possibly the dev portal) which needs to be addressed urgently. There's a history of apps affected by this issue and possibly more apps to be affected in the future if the issue goes unfixed.

                                  The problem starts after a certain app update. The symptoms are as stated in the title. Certain users who had installed the app prior to the problematic update are affected. Fresh users are not affected by this issue. While it is possible to reinstall the…

                                  • Missing XAML DataBinding features from full WPF

                                    Original WPF had lot of useful XAML DataBinding features, that I miss in Windows 8.1/WP8.1 and that I'd like to see in the future version of WinRT, for instance:
                                    - Bindable Runs
                                    - BindingMode.OneWayToSource
                                    - IMultiValueConverter and MultiBinding
                                    - Binding to static properties

                                    • 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.

                                      • Fight spam/fraud apps more aggresively

                                        There are several developers using dishonest methods to boost their apps, including fake ratings. Those apps are as good as useless to consumers (cheap website wrappers etc.) and still have dozens of maximum ratings shortly after being released. Those apps get ranked high in the listings and take away the place of the few others that actually are good.

                                        Reporting usually takes several days or more than one week until something actually happens. Also, I've heard that MS just warns those devs, but even lets them keep obvious fake max ratings. This just makes me angry as a serious developer!
