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?

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".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can support and comment on it.

If it doesn't exist, you can post your idea so others can support it.

  1. 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.

    • API Access for Quick Access Area in file explorer

      On Pre Windows 10 (tested XP-8.1) i was able to create a link in the favourite section of the file explorer (done with WshShellClass). With the quick access bar in windows 10 it's not working anymore since quick access is something new (like it so far).

      Please provide an API for accessing quick access. A Bonus would be to be able to set a link for all users (incl. the user accounts to come).

      .Net API preferred, at least Win32 API

        We are currently investigating how an API like this would work given a user could remove the item from the Quick Access area inside the file explorer. One thought currently is this would be a user opt-in feature where a user could deny your app from being allowed to even add it.

        We would love to hear the scenarios on how your app would use such a feature and some edge cases that would be relevant to you. This will allow us to properly form true developer driven scenarios.

      • Ability to run and use an emulator image in as a remote VM

        A developer should be able to run an emulator instance outside of the developer's environment, and be able to connect/deploy/debug into that remote VM.

        Potential scenarios:
        - Developer doesn't have SLAT on their machine and wants to run the VM on a SLAT capable machine/server
        - Developer is running their dev environment in a virtual environment (e.g., local Hyper-V, remote Hyper-V, Parallels) and wants to run the emulator in another child VM on the same physical host they are running on (since she can't run a VM inside of a VM)
        - The ability to run a dev environment fully…

        • Live tile animations or live tile from xaml

          Live tiles are great. Would prefer some way to great animated live tiles like the Xbox games or music apps.

          Also good if we have a convenient way to create live tiles from xaml. Currently need to generate a bitmap image which not works well for list, etc...

          • Debug over Wifi

            When you unplug a WP device from your computer while debugging, you get an error message that the device on an IP address and port is no longer responding. If the debugger connects to the phone via IP, then why not allow for debugging over the local network? That way, someone can develop for Windows Phone in a Hyper-V VM, and still debug on a physical phone, just without plugging it in. There ought to be a way to build a Debug Agent app that can broadcast itself to the network so Visual Studio knows where to look.

              • Using SmartPhone Screen as mousepad & virtual Controller for XBOX/PS

                From past few day I am working on an innovative idea.
                The idea is:-
                Why not use your smartphone as a xbox, ps controller. Why not use it as a mouse.

                controller:
                If you donot have joystick to play your xbox/ps games just connect your phone to xbox/ps via data cable and use the virtual controller on your smartphone screen as a real gaming controller.

                Mousepad/touchpad:
                Just connect your smartphone to computer and use it surface as mouse

                The problem I am facing:-
                1. In can make the Gui but how the will the xbox/ps recognize that this is a…

                • Set break/trace-points in XAML x:Bind to have it set in code-gen

                  When debugging XAML apps, it should be possible to set a breakpoint or tracepoint on an x:Bind and have the debugger stop on the code-gen binding.

                  The generated bindings code is very large and not easy to follow. Further, it doesn't even exist until compilation and even then isn't visible to the user in VS.

                  The idea here is to set a breakpoint or tracepoint in XAML and have VS break on the appropriate code-gen method instead.

                  • Detect VPN status

                    When a VPN is configured on a Windows Phone 8.1 device, non obvious badness will occur.

                    Even if it is not currently active it will intercept local network traffic and prevent some apps which are supposed to operate against a home network from working (UPnP, network shares, home media sharing, etc).

                    There is no way with the current SDK for a developer to detect this.

                    This leaves developers with only unappealing options:

                    1. Suffer with negative ratings because of broken functionality with apps that worked under 8.0 or without a VPN.
                    2. Prompt all users with a warning that they…

                      it would be helpfull to have a passwordBox like control which supports Number only keyboard. Numeric only passwords makes more sense for Smartphone world as its fast, convenient and easy to type.

                      • active installations Vs total downloads

                        It would be good to know not only the number of downloads but also how many are active still.
                        If you have seen the google store they show active installations more prominently than total download count - and that actually makes sense considering the amount of trash apps going around in all the phone o/s .

                        • Get currently playing song information

                          Within Windows Phone 8.0 it was possible to use the Microsoft.Xna.Framework.Media.MediaPlayer to get information (song, album, artist name) about the currently playing songs. WP 8.1, RT and Universal don't provide a way to read this information, I can only write them using the SystemMediaTransportControls.

                          Pleas bring back the capability to read this information.

                          • SIP Stack

                            A business feature that would be really nice to have support for it the ability to tie into a VoIP network for voip phone calls... the most common architecture is the SIP (Session Initiation Protocol). So I would like the ability to configure a SIP client that ties into our VoIP PBX and phone system.. so my WP7 would basically become my desk phone (extension). The only way this would really work well is if it ran in the background like the phone's native phone functionality.

                            • Expand/Enable Universal Windows Platform to Transpile to JavaScript (iOS/Droid Compatibility)

                              Companies like CSHTML5 (http://cshtml5.com) and DuoCode (http://duoco.de) are already doing this, but it would be great to see this effort officially adopted into the Microsoft Universal Windows Platform.

                              Using Roslyn (as DuoCode does), UWP Applications written in Xaml and C#/VB.NET get transpiled into JavaScript and rendered via HTML5 canvas. The results of which could be hosted anywhere that HTML5/JS can run, notably iOS and Droid platforms. Or even on a regular ol' website.

                              A mechanism that operates like PhoneGap/Cordova would have to be implemented so that access to external hardware APIs can be achieved.

                              That way,…

                              • Windows 10 UWP should support Reflection.Emit for Mocking frameworks

                                The lack of Reflection.Emit in UWP significantly impacts the ability of developers to create clean, AAA-compliant unit tests in an MVVM environment (the recommended architecture for building UWP apps). With no Reflection.Emit it is impossible to build a Mocking framework for providing testable implementations of interfaces used in Dependency Injection.

                                  • Documentation for App URI Schemes

                                    The windows phone developer site should have a place where app developers can search for URI schemes used in other windows phone apps, and get relevant documentation for them.

                                    When submitting an app the store submission process should prompt you to link to documentation for any URI schemes your app includes in the manifest file, or mark them as private URIs if you don't want to document them.

                                    This idea came from a conversation around Matt Lacey's blog post: http://mrlac.eu/1lxwDi4 where he found over 300 URI schemes from some of the top apps in the store, many of which do…

                                      • 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。

                                        • Ancestor binding missing

                                          Currently the RelativeSourceMode only supports None, TemplatedParent and Self.

                                          Would be really helpful to have FindAncestor API added, just like in Silverlight 5 and WPF.
