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. Improve WinRT Frame caching and navigation behavior

    Windows Runtime API has presented Frame class, which page caching and navigation logic differs from a corresponding Frame class from Windows Phone Silverlight API set. This new Frame class gives a lot of pain to developers, because in many cases it cannot provide such app and navigation state management, which can be used to create good and predictable user expirience. Therefore, I want to request adding of some improvements in WinRT API to bring Frame's behavior closer to it's analog from WP Silverlight.

    • Allow unsafe code

      Full unsafe code support would:
      1) Allow more code to be shared across platforms, and
      2) Increase the performance of applications that needed it.

      Here's a use case example:
      I'm the author of BEPUphysics, a real-time simulation library. I wish to support many platforms as best I can with as much common code as possible. Unfortunately, in the current situation, I can't have the best of both worlds. If my goal is optimal performance, I must maintain separate codebases for a bunch of low-level queries and data structures. On the other hand, if my goal is as much common code…

      • 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."

        • 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.

            • 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。

                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.

                • Create a Custom RichEditBox with all the basic features Like Text Formatting, Support for Inking Like OneNote

                  It is very difficult to Create a Custom RichEditBox with all the basic features Like Text Formatting, Bullets and numbering, Support for Inking Like OneNote and also to support adaptive layout, that's too much work for basic Text editing. So my opinion is to create two new controls. One is TextCanvas for Display and Editing both Text and Inking. The other is TextCanvasToolbar for Text Formating and Ink editing.

                    • 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.

                      • 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.

                          • We need a classic TabControl for Desktop applications

                            For a classic desktop application, we need a TabControl. Currently you can use the Pivot or there are 3rd-party vendors providing a TabControl. But as this is such a central control, it should be part of the platform.
                            If you build it, it would be great if you could add configurable close-functionality to the tab-header that is bindable to a ViewModel.

                            I’ve spent some hours to build a small MVVM/UWP/Pivot Prototype that does the typical stuff we do today in WPF with TabControl. And I was impressed how far I got. Sample is here:
                            https://github.com/thomasclaudiushuber/Uwp-Tab-Control-Spike

                              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.

                                • Enable WinAppDriver for Xbox and Mobile

                                  Right now WinAppDriver only works on desktop.

                                  Getting these capabilities across the Windows ecosystem would fulfill the promise of a unified Windows. Making it possible for us to write tests, and code once and have it being tested in an autonomous way. So that in theory, our applications could report and find bugs for us.

                                  Before our users find them.

                                  Thanks in advance. Looking forward to the progress you're doing :D

                                      • 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!…

                                          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.
