Universal Windows Platform

Welcome to the Windows Platform Developer (WPDev) Feedback site. This feedback forum provides the WPDev community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center Store (developer portal, back-end services, reporting/analytics and process)
  • Windows Stores (Windows and Windows Phone)

Your suggestions will be reviewed by the Windows platform developer team, providing feedback to help with planning ideas and to better understand how developers are using the development platform.

What this forum is not intended to cover or capture:

If you’re new to this whole UserVoice thing, we’d like to note two important things 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 dev platform?

  1. PhoneのOS側でユーザーが認証済みの認証情報が使える、Live SDK相当のAPI。

    現状、SkyDriveへのアクセスなどLice SDK (API)を使う場合、ユーザーに認証情報をOSとは別途入力してもらわないといけない。
    また、OAuth認証をする場合、そのための画面遷移を用意するのも大変です。
    (Live SDK Developer Previewなどありますが)
    SkyDriveへのアクセスやその他のLive APIについて、ユーザーが追加で認証情報を入力することはせず、利用できるSDKがあるといいのではないでしょうか。
    アプリに対してOSが使っている認証情報を使ってもいいかの確認画面が出て、ユーザーが同意すれば、アプリに認証情報を渡すことなく利用できる形態であれば、アプリ側が認証情報を持つ必要もなくなります。

    • Enable Hyper-V on all version of Windows

      For developing and testing virtualized apps with the latest features we need Hyper-V but it isn't available on all versions, so our best option is install Linux.

      • Allow subpixel font smoothing (DirectWrite) in UWP apps

        Currently UWP have less readable grayscale font smoothing. It makes UWP apps look worse than desktop apps on standard DPI screens. Allowing subpixel font rendering would make them look on par with desktop apps.

        • Emulating Camera

          It would be extremely helpful if the emulator could use webcams as camera emulation. Otherwise AR scenarios are hard to develop without a range of devices. It has become even more needed with the addition of WXGA and the different scalings in WP8.

          • Donationware ability for Windows Store

            It's a lot easier to build a following when it's free. Keeping this in mind, was thinking of making some of my products donationware. Would it be feasible to somehow make this type of offering as part of the store?

            The ability for an end user to donate allows me to make the app free. Donations should be supported

            Any feedback is appreciated, Thanks, John.

            • Implement System.ComponentModel.TypeConverter in WinRT APIs

              TypeConverter is helpful because it allows the author of a type to provide intrinsic support for determining to/from which types a type may be converted and actually converting between types - most typically for converting to/from string but other types as well.

              • 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.

                • Java SDK to develop Windows apps

                  Java is the most used language and the main factor to run Android forward. C# is better but still most developers (more then 40%) like to code in Java because they used to it sinve they started to study Object Oriented Programming in institutions. Making Windows Phone SDK that supports Java and a better documentation will increase apps and games count in the store. You can take example from Microsoft Azure, they are leading in their field as they gives support almost every developer by providing his language support. Be possitive Microsoft, as a Microsoft fanboy since age 6 I…

                    • Make the emulator emulate the ARM CPU, like in WinMobile

                      Now that native development is an option, it's very frustrating that one can't debug the native code that's being executed on the device without a real device.

                      Back in the Windows Mobile/CE days, Microsoft had a Device Emulator that would faithfully emulate an ARM CPU and would execute exactly that same code that eventually went to the device. This capability was essential for certain low-level tasks like native crash investigation, debugging stack clobbering scenarios, deep optimization with inline assembly (e. g. for NEON) and such. Now that capability is lost. Please bring it back.

                        • BackgroundAgent実行間隔の短縮

                          現状の最低30分間隔という実行間隔は位置情報アプリを作成するには長すぎます。
                          個人情報の問題などもあるのはわかりますが、現在の仕様では特に地下鉄やオフィスビルなどを多く利用する都市部では使い物になりません。
                          せめて10分間隔、できれば任意の間隔を指定できると嬉しいです。

                            • Interapp Communication API

                              Allow apps to act as data sources for other apps.

                              Build on WCF to allow on-phone app-to-app communication. This is something that Apple just announced and Google is expected to soon. Get this working ASAP so Windows Phone doesn't get left behind.

                              Allow JSON and/or XML to pass data between apps.

                              Use a URI to query apps, ie:

                              facebook://Friends?DateOfBirth=DateTime.Now.Date

                              Most importantly! Make apps request permission the first time they talk to a new app, then let it happen in the background. I shouldn't have to launch Facebook just to get to the data.

                                It would be really cool if developers could get api access to Xbox Live Gamertags, that way they don't have to make users create a new account just to play multiplayer games. It would also help a lot for leaderboards too.

                                  • APPHUB で審査中のアプリの申請取り消しができるようにして欲しい。

                                    アプリ申請後にアプリの不具合を発見してしまうケースが(よく)あります。

                                    不具合によっては、審査結果が出たとたん再申請をする場合もありますので、早めに気づいた場合に申請取り消しができれば、開発者も助かりますし、審査側も無駄な審査に時間を費やす必要がなくなります。

                                    是非、審査中にも申請取り消しができるようにしてください。

                                    • Deploy while debugging/deployment should unlock the screen

                                      When developing with the phone connected via USB, having the screen lock itself is very annoying, and makes app deployment fail.

                                      Some WP7 phone (not the AT&T Samsung Focus) have a "never" screen timeout. However this is for battery and powered scenarios, and you don't want to be manually switching it back and forth all the time. Some of us are stuck with a phone that locks itself all the time. The screen lock also interrupts or prevents app deployment. This makes Visual Studio fail to start the debugging session.

                                      An app deployment should unlock the screen and reset the…

                                      • Support for OpacityMask in WinRT

                                        I understand that the OpacityMask was removed for UI performance reasons, but just because it may be over utilized by some doesnt mean it should be dropped all together.

                                        • Add API for developers to make true Live Tile Clocks

                                          I have an app in the store to make a live tile clock. It worked fairly well on WP8.1, but now on W10M, when you go to the start screen, until the tile notification refreshes, the live tile shows the default app tile. I checked with multiple clock tile apps in the store and they all have this same fundamental issue. (blank or app logo on tile until tile notification refreshes). What would be nice is, instead of sending tile notifications for every minute, if there was a way to better adjust the live tile image every minute. Something like…

                                            Hey William! Andrew from the Windows Notifications team here.

                                            One thing you can try doing is not setting an expiration time on your tile notifications. Sounds like you’re setting an expiration time, hence why the tile is reverting back to blank. If you don’t set an expiration time, it’ll briefly display the previous time and then flip to the current time – which might be a better experience.

                                            But maybe if tile notifications could be marked as “Display instantly”, clock and calendar tiles would be able to function better.

                                            I believe we delay displaying the notifications for performance reasons (we don’t render them till you open Start), but we also have a little delay in there to “cascade” the displaying of notifications, so everything doesn’t flip all at once. But by cutting out the second step with the “Display instantly” flag, it could maybe work.

                                            Anyways, thanks for the feedback!…
