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".

    • 日本語版で、さして意味のない縦書きUIは止めてほしい

      日本語版のWindows Phoneでは、ロックスクリーンをはじめとして、Poeple Hubの発言者表示やMusic&Video Hubのメニューなど随所に縦書きUIが織り込まれています。

      一概に縦書きを否定するつもりはないのですが(ロックスクリーンやカレンダーなどは確かにそこそこかっこいいとは思います)、People Hubなどはタイムラインに無駄な余白が入りまくる、英語名の発言者の名前が非常に読み難い上に半分ぐらいで切れてしまって誰だかわからないなど、機能を阻害している部分があるように感じられますし、デザイン上もMusic Hubのように日本人が見ても明らかに不自然かつガイジン臭いカッコ悪さが気になります。
      また、アプリケーションから縦書きメニューなどが簡単に使用できるわけでもありません。本当に使い勝手が良いのならばアプリからも容易に使用できるよう環境が整えられていてしかるべきです。それがなされない、ということは、ようするにデザイン上に小手先勝負で奇をてらっているだけといわれてもしょうがないのではないでしょうか?

      とにかく、正直WP7.5での縦書き表示はWindows Phone本来のcoolさを少なからず損なっていると感じられるので、次期バージョンではデザイン全体の再検討を含めて再考いただきたいと思います。

      • Full file management Windows.StorageFile, Windows.StorageFile.KnownFolders and raw Media file access as in Windows 8.1

        Hi,
        I think it's useful if both windows phone 8.x and windows 8.x will have a similar way to access filesystem content and implement ALL the APIs here:

        http://msdn.microsoft.com/en-us/library/windows/apps/hh465199.aspx
        http://msdn.microsoft.com/en-us/library/windows/apps/hh464978.aspx
        http://msdn.microsoft.com/en-us/library/windows/apps/windows.storage.knownfolders.aspx
        http://msdn.microsoft.com/en-us/library/windows/apps/jj218966.aspx

        In particular, having only the possibility of accessing media files through the XNA API doesn't deliver a UX on par with other platforms.

        As an example, we have a media player app for iOS, Android, Windows 8.1 that does some sound processing and mixing between mp3 files available in the library and the recording of the mic.

        Currently, it is not possible for us to release this feature…

        • Allow settings based on location, time, WiFi network, etc.

          I would like to have setting profiles that enable based on certain criteria.

          Examples:
          During sleeping hours, do not alert me for emails, twitter and facebook notificaitons.
          When on my home wifi network, switch ringer to loud.
          When my work wifi is detected, turn ringer off and set mode to vibrate.
          When my work wifi is detected, turn on battery saver.
          When I am at a church, restaurant, or a movie theater, disable all notifications.

          • AppHub の申請却下判断が担当者によって違わないようにして欲しい

            AppHub に何度か申請をしていると、何らかの理由で申請が却下されることがありますが、申請却下判断がまちまちなように見受けられます。
            拙作 Nel の話で申し訳ないですが、一度 3.6 Adult Related Contents 違反で却下されても、再度ほぼ同じバイナリの XAP を申請したところ受理されました。

            このようなことは開発者側に思わぬ恩恵をもたらす場合もありますが、出来るだけ基準が一律の方が開発側としても対処しやすく思います。

            • Avoid Tolls in Bing Maps Navigation

              You should be able to select alternate routes in Bing Maps. This should include a way to avoid highways, toll roads, and heavy traffic. Selecting a diferent route in general would be a nice feature.

              • SMS Access API

                I want to be able to write an application that processes the user's received and sent text messages (SMS) (subject to applicable application policies), including but not limited to retrieving content, sender (phone number and/or contact) and exact time sent.

                The purpose of such an application could be to make further use of the information, e.g. for archival or post-processing purposes, or to automate the use of appropriate SMS services, e.g. regional information services.

                  To support things like midroll video advertisments, multiple MediaElements are needed. This is supported in Silverlight for the web.

                    • WiFi APの位置情報登録の充実と精度向上

                      日本の都市圏では、主要な駅や公共施設はほぼ例外なくWiFi APが設置されています。これらの位置情報をGPSによる自動登録に頼らず、クロールして登録してください。これだけで地下鉄、屋内等での位置情報アプリの利用価値が飛躍的に上がります。
                      また、ポータブルWiFiAPや列車内APなどがGPS情報から自動登録されてしまい、おかしな位置情報を表示することが少なからずあります(Mangoでほぼ改善された?)。これらの移動するAPを位置情報DBから排除してほしいです。また、おかしな位置情報を報告する手段があると精度向上につながると思います。

                        Currently it is not possible to debug and test applications that reads data from the SD card in emulator, until you have device with MicroSD. It would be nice to have an option in emulator to mount disk, removable storage or folder, that will emulate behavoiur of SD card.

                        • Assembly Binding Redirection support

                          We really need Assembly Binding Redirection (or Publisher Policies) is Windows Phone!!

                          Lets say you have a library A that the developer strongly signed.

                          Now let's say you have two other libs, B and C, and both of these depend on A.

                          If B and C were to be built with different versions of A, how will he use B and C on our projects?

                          In the .NET Full Framework, we would use a .config file to make Assembly Binding Redirection (normally, we would point all versions of A to its most recent version), but this is not possible right…

                              • 横長タイル使用を一般開発者のアプリへ開放してほしい

                                Pictureハブなどのような、横2つ分の大きさを持つタイルを、一般開発者にも開放してもらいたいです。
                                1つ分のタイルは多様な情報を表示させようと考えたときにはあまりにも小さすぎ、表示を断念することも少なくありません。
                                ユーザの利便性のためにも、開発者の利便性のためにも、そしてアプリケーションの多様性をさらに活性化させるためにも、是非開放をお願いします。

                                • Native SQLite database support

                                  In addition to the existing database support, please add support for SQLite databases, without a LINQ layer like for SQLCE. Just a raw database with SQL commands like we are used to. SQLite is platform independent, that means it is easy to exchange data between Windows, Windows Phone, Android and iOS devices.

                                  • Access Podcasts through MediaLibrary

                                    Provide access to the podcast episodes that are in the media library so that they may be used to construct, for instance, custom playlists.

                                    Developers wishing to leverage the Zune media platform to offer improved or tailored podcast playback experiences are currently blocked. Instead, an app developer must re-implement all the podcast management functions that are already well handled by the device and the PC Zune software. Once access to a user’s podcast subscriptions and already downloaded episodes is enabled, developers may easily write applications which enhance the existing playback experience.

                                    This idea could be relatively simply achieved as a…

                                      Currently there are API to read the Phone Book, but no API to read the Call History. This should be enabled to write powerful Phone Call apps with more features

                                      • Cortana API

                                        It will be great to provide an API allowing developers to interact with Cortana following this workflow:
                                        1- Get command from Cortana.
                                        2- Do some processes.
                                        3- Get back to Cortana with response data (do not exit from Cortana UI).
                                        4- Cortana responds the user.

                                        • Preserve exif information of Images while saving in Isolated storage or Media library

                                          We can access exif info (limited) using a Picture object when dealing with Media library. But if we try to save an Image within app inside Media library or some Isolated storage we can't prserve exif info of that image. A better manipulation of exif APIs will be very helpfull.
