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. MediaPlayer support for BackgroundAudioAgent

    In trying to develop a custom playlist application, it is apparent that it is impossible to integrate the BackgroudAudioPlayer with the XNA.MediaLibrary. This means that applications that wish to use the capabilities of the BackgroundAgent are restricted to using only local audio files that are deployed with teh application, or audio streaming sources. There is no way to access the phone's MediaLibray.Songs to have the BAP play these files in teh background. This is highly restrictive because we can only use the MediaPlayer for foreground applications. Unless of course we go with a predetermined SongCollection such as SongCollection limitedPlaylist =…

    • SJIS, EUC のエンコーディングのサポートをして欲しい。

      外部データの読み取りなどで未だに SJIS や EUC を読み取らざるを得ない場合があります。この場合に備えて System.Text.Encoding で SJIS や EUC のサポートをして欲しい。
      PC版の Silverlight でもサポートされていないようなので、難しいかもしれないですがお願いします。

      もし標準サポートできない場合は、代わりに codeplex 等で C# 実装の MS謹製? エンコーディングクラスを公開して頂けるとありがたい。

      当たり前の事ですが、 IE9 で SJIS, EUC のページを参照したところ正しくエンコーディングが行われているので、WP7 どこかにエンコーディングを行うコードはあるはずです。

      • How many users are using which version of my app?

        I have released several versions of my app throughout its life cycle. Knowing how many users are using which version of my app would be great.

        Something like: %10 is using version 1.0.0.0, %20 is using version 1.1.0.0, %70 is using version 1.1.1.0 etc. on my dashboard.

        • Enable removing language code from the "language history"

          If you ever selected "ru" and "ru-ru" laguages then it causes Tile localization show the en-us(default) tile localization to show.

          When I removed the "ru" language code and published my new version, the old version still remains with "Replaced and unpublished". Wich means the new version not fully replaced the old version.
          And this causes me very serious problems:

          1. Some of my users will still receive the old version of my app (after weeks). The store randomly gives the old or the new version of my app.

          2. My app has a WP7 version and a WP8 version XAP…

          • Fix VoiceCommands so they work whether the app is in the foreground or not

            Right now, Voice Commands registered for an app only work when an app is off, or in the background. They do not work if you are in the application already, and use Speech from the Windows key to navigate somewhere else in the app.

            To the end user, it appears that the command is recognized and the system is taking you there, then it closes without actually doing anything. This appears to the end user like a bug in my application, not a system-wide OS bug.

            I understand this was not necessarily the designed use case, but consider that the…

              • Create option to auto sync with Skydrive with no compression as soon as connected to WiFi.

                The current auto sync with skydrive compresses pictures before uploading. This way still no real backup is made. Since skydrive offers 25gigs more then enough space is available for backing up in full size. Create an option to 'only upload to skydrive when connected by WiFi' and an option to choose to compress or not.

                • Full file manager is missing in WindowsPhone8

                  Hi. I'm using a Windows 8 phone and have the latest developer update Gdr3. I'm frustrated because of the windows phone limitation. What is the fun in keeping such limitations. My concern is why is windows phone lacking the most needed file manager which is found in phones launched before 5 years. Although windows phone is very fast and has great response as compared to the latest phones. But... I cannot save downloaded files to desired locations. while replying to an email,there is no option of attaching documents, videos, other files except photos. Even the Microsofts site doesn't allow you…

                  • Add Header property to TextBox control

                    • Support for asynchronous pluggable protocol in IE (Internet Explorer)

                      Allow custom URI's in Internet Explorer, like nabto://device.company.net.
                      Basically implement the IInternetProtocol family of COM interfaces on Windows Phone 8 and allow us to add our own protocol handlers (in the Registry) - it is possible on Windows 8.

                      • App Metadata Should Be Part of the Project

                        I would like to see the metadata be part of the project in VS. This would allow (as others have suggested) a more streamlined process for tracking changes and perhaps even uploading a single package without having to fill in the blanks. An editor (like properties/settings) would be great.

                            Many applications like need the Accelerometer or G-Sensor for working correctly like alarm clocks that wakes when the best sleep phase has been reached or Pedometers. But it currently only works if the Display is turned on and Lockscreen is deactivated. It would be more useful to activate this feature in Lockscreen or Low Power Mode

                                    • Provide access to Mango scan text API

                                      Mango provides a good feature to scan an image for a text. It would be great to provide a new launcher/task which uses this new existing funtionality to get a string from an image.
                                      Otherwise we need to create our own control to scan an image and extract strings with an ocr library. I'm not happy to implement something which is already there.

                                      Even if this API would use a webservice and needs network access, I would be fine with that.

                                      • No Pin Option for Kids Corner

                                        If you activate a pin for the phone Kids Corner automatically gets a pin too. This means that you as a parent have to unlock the phone for your child. (Or give them the pin which kind of defeats the purpose.)

                                        Feature suggestion: I would like to be able to set "no pin" in the settings for Kids Corner. Additional feature option would be to specify a different pin for Kids Corner (1234) :)

                                        It makes no sense to have a pin for Kids Corner if you have, say, only configured a few games in that area for your child!
