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".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can vote and comment on it.

If it doesn't exist, you can post your idea so others can vote on it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. Media playback on emulator should match Phone

    The phone currently plays a large selection of media formats (MP4, M4V, 3GP etc) that aren't supported in the emulator. This makes apps that use these formats extremely hard to debug.

    Would be awesome if you could fix this :)

    • Add a ShowContactTask to show a specific contact's details

      If I have an app that shows a filtered subset of a user's contacts, I should have a way to click on that user and show the user's details in the native experience.

      I am familiar with the suggestion to take the contact's details and re-create them in your own UI... which would be great if the API exposed all of the user's details (like the Anniversary) which it does not. Also, having a ShowContactTask would allow me to give my user a quick shortcut to post a message on Twitter or Facebook without having to implement those SDKs (especially…

      • Task-based operations generation when adding Service References

        For .NET 4.5 and Windows Store apps it is posible to generate Task-based asynchronous operations when we add a Service Reference to the project.

        That is still not possible for Windows Phone projects, and we have to handle with completed event based asynchronous operations.

        Task-based operations would make the code much more clean and readable.

        • More background tasks to be allowed.

          simple. let there be more than 9.

          A user should be able to deside between power drain and functions.

            • Viber for Mango!

              Viber is an extremely popular application similar to Tango, but better in some ways.
              It has more users -> more people to call.
              The application is built into your contact list (no application to open).
              You can text people using Viber.

              Here is the info thats available on the Website of Viber:
              Viber is an application for free international calls and text messages to other Viber users using 3G or Wi-Fi. Uses your existing contact list - check out which of your phone contacts and friends is already on Viber so that you can call and text them for free.

              • Access to network share

                I have a file server which hosts a lot of my documents, pictures and music. With Android it´s easy to browse the server with "ES File Explorer". This is single reason why I keep my Android phone around.
                I really wish it was possible to access my file server from my Lumia 800 too.
                It´s not only tedious to use Zune for copying my files over, it´s also creating redundancy by keeping copies on another device.
                Yet another reason - it uses valuable space on my Lumia 800 which wouldn´t be necessary if I could acces the file on the…

                • Support SSL certificate pinning

                  There is SSL/TLS socket support in Windows Phone 8. However, currently no WP8 platform component seems to support SSL certificate pinning.

                  When a SSL connection is created, there is no way to inspect the x.509 certificate chain returned by the remote server. I want to implement certificate pinning for additional security in my app and therefore I need an API to read the values of individual x.509 certificates.

                  I am not the only one who needs this: http://stackoverflow.com/questions/17741740/read-ssl-certificate-details-on-wp8

                  Please provide a way to do certificate pinning using platform components in WP8.

                    My company likes WP7, but the nonexistence of visual voice-mail is stopping a switch from the iPhone. Is there a way to access voice-mail metadata?

                      iOSのマーケットには存在するのですが、プロモーションコードの発行機能をつけていただきたいです。
                      レビューサイトに有料のアプリケーションをレビューしてほしいのに、有料版であるがためにレビューしてもらえないなんてことがあります。試用版だけでなく有料版で利用できる機能までレビューしてもらえればそれだけアプリの魅力を紹介してもらえると思います。アプリ側で同じような事はできるでしょうが公式にこのような機能が追加されればうれしいです。

                        • Image Classes than be run on non-ui threads

                          Currently when using WriteableBitmap or decoding image data you have to do that on the UI thread. This is very problematic since if you need to do any heavy image processing you're slowing the UI and negatively affecting the user experience. It would be great if there were specific classes that could be instantiated on non-ui threads (and then loaded by ui-thread image objects)

                                • Enhance Microsoft.Phone.Scheduler Alarm and Reminder classes

                                  The Alarm and Reminder classes in Microsoft.Phone.Scheduler are very limiting and do not allow for any customization. Ideally these classes would be extended to accept a UserControl object that would be shown instead of the standard Title. The UserControl should run in the context of the application that created the Alarm or Reminder, and as such would have access to the appropriate view models. From there the application could be fully launched if desired.

                                  • Callback for all tasks and launchers

                                    Would be nice to have a callback on for example the phonecalltask so that we can determine wether or not the user actually did press "call" or "cancel". Same for other tasks and launchers.

                                      Allow the user the option of choosing a non qwerty keyboard layout, as a full keyboard can be really frustating at times due to the small keys.

                                      • WP8 must support Dual-Sim support.

                                        Business man uses two phones for their works and private.

                                        Nowadays, there is a lots of Dual-Sim supported phones. Android support dual-sim architecture on their OS level. But WP8 doesn't.

                                        • WP7 Notify App when call ends

                                          When user is with in an app and there is an active call in progress the App should receive notification when call ends. Currently there is no support for this and really hard to understand when the call ends. This for example can be used to show meeting minutes screen as soon as a call finishes. I see more uses than simple example I have mentioned below.
