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.

    • API to directly modify system properties (wifi, mobile data, bluetooth, volume, airplane mode, etc.) instead of using launchers

      This can be made safe for users by making the certification requirements very strict when utlizing those APIs with requirements for very clear, concise notice to the users.

      • Improve SMS delivery notification

        Now the SMS delivery reports come in as separate text messages which is very inconvenient. Wouldn't it be nice if - when enabled - a delivery report was shown right next to the message as an icon (approval mark or something)? You would instantly know that the SMS was delivered and if you wanted further details (delivery time) you just click on it.

        • PhotoCropTask

          When you use the PhotoChooserTask and specify a PixelWidth and PixelHeight, when an image is chosen, the user is provided with a cropping tool that is outstanding and difficult to duplicate. Please provide a PhotoCropTask that takes an Image(Byte[]) and provides the same crop tool. Include a PixelHeight and PixelWidth as optional parameters so an aspect ratio can be included.

          • Allow direct dialing on PhoneCallTask

            Allow users to choose if they want the "call/don't call" prompt dialog when an app invokes PhoneCallTask.

            Fast dialing apps are killed by this limitation.

            The same way a user can grant for background tasks, he could grant the app permissions to make direct dialing.

            • 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?

              • Extend the DeviceNetworkInformation with MNC and MMC

                Extend the DeviceNetworkInformation with the MNC (Mobile Network Code) and MMC (Mobile Country Code) values. We have an application that needs this information, and we cannot get it from the current DeviceNetworkInformation.CellularMobileOperator property, because the operator name can change over time.

                • Detect whether user has rated the app or not

                  As a developer, the only way to increase app ratings and review is to prompt user.

                  At present there are no APIs to detect whether a user has rated the app or not. Some users get annoyed and down rate the app due to this very reason.

                  This is a very basic piece of functionality that has been missing for long.

                  Please provide us a simple API that gives us this information.

                  Alternative for us to continue work towards this http://invokeit.wordpress.com/2013/10/16/detect-whether-user-has-reviewed-your-app-or-not-wpdev/ however I am not keen on this purely because I can see this being abused very easily.

                  • 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.

                    • Windows 8 like Search Contract for Search Button

                      It would be nice to have a SearchContract so the Bing Key could be more usefull. You could enter you search term and either press enter to bing for it or scroll down a list of search contract enabled applications blow the Textbox and tap the application you want to search. Of cause the nice images in the background wouldn't make that much sense anymore but the usabilty would be a lot better.

                        • Add a SavePng extension to WriteableBitmap (similar to SaveJpeg)

                          When you create a tile dynamically, it is common to want to save it as a Png file so that it uses transparency (so that it respects the theme accent color).
                          However, there is no built in method to save a WriteableBitmap as a png.
                          There is however a nice extension to save it to jpg, but that doesn't help if you want to use transparency to leverage the theme accent color in your tile.

                          I think many apps that need to generate a tile dynamically will encounter this issue.

                          • Allow Developers to 'roll back' to a previous update without re-certification

                            Occasionally an update to an app gets past developer & certification testing and is released into the wild. Even if the bug is an easy fix for the developer it will take the certification team the standard 4+ days to certify the new build and publish it.

                            Instead of this we should be allowed to roll back to a previously published version without going through certification. That way the users will be back on a stable release (or will not be prompted for an update if they were still on the previous release) and the developer will not feel rushed…

                            • Self Signed Certification SSL HTTPS

                              For those of us wanting to provide free applications it would be nice if the WP7 supported self signed certs or the very least a widely known free SSL authority.

                              Add ServicePointManager.

                              Or at the very least add a free service to your accepted list of SSL authorities. Like cacert.org for instance.

                                  Microsoft should expose GPS based API's that can trigger after say 5 min or 10 min departure from a specific GPS location. This would be very usefull in apps in customizing the reminders.

                                  • 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!

                                      "Segoe WP" という既定のフォントがアプリケーションテンプレートとして利用されていますが、表示言語が日本語にも関わらず、中国語のフォントが選択されています。Windows Phoneのユーザーが利用している表示言語に応じて、フォントフォールバックの優先順位を表示言語が優先されるようにして欲しいです。

                                      • ペアレンタルコントロールか年齢認証をつけてほしい。

                                        別に提案した「2ch ブラウザの申請を通してほしい。遮断する理由が聞きたい。(http://wpdev.uservoice.com/forums/136286-app-platform-japan/suggestions/2323141-)」ですが、聞くところによると 2ch は U13 コンテンツが存在しているために一律審査却下の方針をとることにしたようです。

                                        審査を行うマイクロソフトの立場は理解できます。また開発者自身が U13 コンテンツに誘導した等の理由で訴追されるリスクを回避することができるので、ある面からは必要不可欠な判断かもしれません(ここではこの議論はしません)。

                                        今後このような事があっても対応できるように、
                                        1. OS 自体にペアレンタルコントロールの機能をもしくは年齢認証をつける。
                                        2. アプリ側の Capability に Adult Related Contens があるソフトは起動しない。
                                        などの処理を行ってほしい。

                                        • Paste into phone number field of dial pad

                                          I don't want to have to memorize or write down a phone number before going to the dial pad. I want to copy it from a site and paste it into the dial pad. It would be nice if when someone texts me a number, I could paste the entire text message into the dial pad and a regular expression would pick out the phone number portion.
