Dev Platform

Welcome to the Windows Phone Developer Feedback site

This forum focuses on the developer platform (APIs, runtimes, and controls) that you use to build great app experiences for Windows Phone. Additional WPDev forums are available using the links along the right of the page. Consumer features suggestions should be submitted to the Windows Phone Suggestion Box site (http://windowsphone.uservoice.com/).

Suggestions provided via the WPDev UserVoice forum will be reviewed and read by the Windows Phone developer platform team, providing feedback to help with planning ideas and to better understand how developers are using the development platform, and all suggestions will be considered.

Two important notes 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 Phone 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. Extend the API to query phone volume and vibration settings, maybe even set them.

    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 :)

        • Integrate BackgroundAudioPlayer and XNA MediaLibrary

          Allow the BackgroundAudioPlayer to play tracks from the MediaLibrary. Or allow applications that implement the XNA MediaPlayer class to run in the background.

          • Video Chooser Task

            It would be good to have a Video Chooser Task that works in the same way as the PhotoChooserTask. The reason for this is for users to be able to do things like apply filters, add audio tracks, crop out a relevant section, etc... of a recorded video and saving it back to the MediaLibrary. I assume saving to the MediaLibrary will be part of the AR functionality in mango anyway?

            • WP7 should support Reflection.Emit for Mocking frameworks & Linq

              The lack of Reflection.Emit in WP7 stops developers from being able to properly test their frameworks. With no Reflection.Emit it is impossible to build a Mocking framework and actually test WP7.

              The lack of Reflection.Emit is also blocking the OData Client Library for WP7.

              • Allows software products from the same Publisher, accessing IsolatedStorage

                Want to have a feature. Allows software products from the same Publisher, accessing IsolatedStorage. And can communicate with each other. Start each other (optional), which can be expanded larger developers ideas and more powerful than iOS and Android system.

                This can save storage space, unified data storage location.

                Or another form. Developers can provide their main program with subroutine. Subroutines can be run separately. Main program can manage/run program. In this way, developers can provide independent extension to process the data.

                Wish to consider this kind of system design.

                PS: above I use the online translation feature.

                  Thank you for the suggestion. We are not adding this capability in the 8.0 release, but know that it is high on the consideration list for future Windows Phone releases.

                  Note that today, publishers can use server side comms/services to accomplish this type of solution, but this is not yet possible for logic that occurs entirely on the device.

                  Keep those suggestions and votes coming!

                • SIP Stack

                  A business feature that would be really nice to have support for it the ability to tie into a VoIP network for voip phone calls... the most common architecture is the SIP (Session Initiation Protocol). So I would like the ability to configure a SIP client that ties into our VoIP PBX and phone system.. so my WP7 would basically become my desk phone (extension). The only way this would really work well is if it ran in the background like the phone's native phone functionality.

                    For vNext it would be really great to have ApplicationData.RoamingFolder supported. It can enable some really cool and also cross-device experiences.

                    • Allow apps to notify user via notification LED

                      When an email arrives, or when I got a missed call, OS notifies via the notification LED.
                      But third party apps don't have the ability to notify the user this way.

                      I realize that allowing raw control will compromise the UX. However, allowing the apps to let the OS know that there is an update, combined with a toast or a tile update would be useful.

                      For ex: when I update the tile, or fire a push notification, allowing to mark it as 'priority', so the OS can blink the light ? (then also need a way to cancel the…

                      • API to write videos to Media Library

                        We are limited of saving the Images to the Media Library.
                        It will be better if user can add the downloaded Audio , Video can add to the Media Library from the Isolated Storage.

                        • Background app execution

                          If iOS and Android can do it why can't Windows Phone? Like all the Timer apps on Android & iOS, they can update the badge numbers real time giving you a true countdown timer experience. Why cant Windows Phone do this? It should be able to do this! Would battery experience really degrade that much? If so me thinks this is a fundamental flaw in the OS!

                            • Enable Toasts from Within Applications

                              The Toast UI metaphor is useful for showing transient messages to the user such as authentication failures or other other messages that do not require the user's immediate attention.

                              In the current ShellTile API, a toast will not be displayed if the current foreground application is the caller of the ShellToast.Show method. It would be great if this was changed so that we could present in-app toasts. We can then user the NavigateUri property to navigate the user to a different part of the app if necessary.

                                • Allow unsafe code

                                  Full unsafe code support would:
                                  1) Allow more code to be shared across platforms, and
                                  2) Increase the performance of applications that needed it.

                                  Here's a use case example:
                                  I'm the author of BEPUphysics, a real-time simulation library. I wish to support many platforms as best I can with as much common code as possible. Unfortunately, in the current situation, I can't have the best of both worlds. If my goal is optimal performance, I must maintain separate codebases for a bunch of low-level queries and data structures. On the other hand, if my goal is as much common code…

                                  • Provide Miracast as a platform feature

                                    Miracast is the industry standard that will allow screen projection to different devices like TVs, stand alone media streamers, etc. From a enduser experience, it provides "Airplay Screen Mirroring" which is available since 2 years on the iOS platform.

                                    Miracast is a industry standard and wide compatibility is expected. Also Android 4.2 comes with support for Miracast.

                                    • Provide developers and API to access default system sounds (such as those found in Settings - ringtones+sounds)

                                      It would be really helpful if, for example, a developer makes an app that takes advantage of the schedule alarm API, and would like to enable the user to select a custom ringtone for that alarm. This API proposal would enable the user to select from many ringtones already available on the phone, and save developers the trouble of having to implement their own custom ringtones.

                                      • Provide a Share Extension to Share Links from IE

                                        In IE for Windows Phone, you have the ability to share a link to the current page you're on from an Application Menu Item. The options are as follows:

                                        Messaging
                                        E-Mail
                                        Social Networks.

                                        I would like the ability to easily share a link to another application. It would work in much the same way the Photo Hubs Extension works. You would see a 3rd party app that supports the Share Link extension. Clicking it would open the app at a specified task. Then, one of the query string parameters that's used to launch the task could just be the URL…
