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. Allow CookieContainer to be Serialized/Deserialized

    Currently, serialization and deserialization of the CookieContainer doesn't work. The documentation says to use the CookieContainer if one needs to save off HttpOnly cookies. It seems that saving the CookieContainer isn't possible.

    "If the server sends HTTPOnly cookies, you should create a System.Net.CookieContainer on the request to hold the cookies, although you will not see or be able to access the cookies that are stored in the container."

    • Triggers for WinRT in XAML additionally to VSM.

      Could you add triggers for WinRT like it is for WPF? Without triggers only with Visual State Manager it sometimes needs to put many additional code to make simple things.
      Also VSM's cannot be applied to styles and you cannot create a separate resource with VSM to apply it to different controls. So you are forced to override control's template every time and this is really bored.

      • 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.

        • Add PowerShell to Device Portal

          There should be a PowerShell prompt in Device Portal that lets me run extra commands.

          • More artwork in SDK

            Distribute more application bar icons in SDK (at least each one used by built-in applications); provide forum/marketplace for other artwork, including control templates & styles.

            • 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.

              • Support Custom Markup Extension for metro style app

                Silverlight has already supported the custom markup extension.

                Because Static, DynamicResource and DataType markup extensions connot be use on metro style app, at least, it is nessesary to support custom markup extension for metro style app.

                  • Support using a Binding in a Style Setter in Window Store apps

                    SL5 (as well as WPF) support setting the Value of a Style Setter to a Binding but XAML Windows Store apps do not (maybe because it was based on a snapshot of SL4).

                    • 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。

                      • 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.

                        • 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.

                          • 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.

                            • 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。

                                  Currently the only way to take advantage of the direct manipulation in a XAML Windows store app is by using a ScrollViewer. However that isn't always appropriate. For example if one wanted to implemented a fixed columns Excel type functionality where the cells of the first column should not scroll horizontally but the cells should participate in the vertical smooth scrolling and where cells in the first row (and header) should scroll horizontally but not vertically. There really isn't a way to prevent some of those from scrolling since the ScrollViewer's Direct Manipulation implementation will animate/offset the rendering in the…

                                    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.

                                      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.

                                      • Allow direct printing without Modern UI print dialog

                                        In Windows Store apps there is no way to programmatically initiate a print job.

                                        Under WPF, it is possible to initiate printing to the default printer by simply calling Print() on a properly configured PrintDocument object.

                                        We have a popular photo booth app in the Windows Store. It is able to provide a fully automated photo booth experience for the user's event guests EXCEPT when it comes to printing. In order to print, the guests must leave the tailored kiosk experience and interact with the local print dialog.

                                        If it were running under WPF, then it would simply print the…

                                          Fix Altitude Bug in GeoCoordinateWatcher and Geolocator when using in WP8. On my lumia 520 (WP8) i get jumping values of altitude, even outdor with a strong and good GPS-signal. The altitude jumps from 27m to 200m up and down, 200m is the right value. The values from GPS-accuracy are top. This occurs In both classes on WP8. I always use the DisiredAccuray = high! I have read, that another user have the same problem with WP8-Phone, like HTC. All GPS-App in the store have the same problem with the jumping altitude.
                                          But i found a solution. If you take…
