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. Provide ability to transfer ownership of app including IAP transfer

    Some people have had other developers submit apps to the marketplace on their behalf for many reason. They may have been in a country that is not supported for example. More then one developer may have worked on the app and are now splitting. Some people may sell their apps to others.

    In all these cases it breaks the update cycle for existing users because the new owner would have to create a new app instead of updating the existing one.

      Starting this month apps can be transferred from one account to another. To start the process you need to open a support ticket to start the process. Once you submit the request, you’ll get a checklist (for example you need to finish any pending submissions, export the reports). The acquisitions, reviews history and users are transferred, though the historical revenue is not transferred. The feature is available to every app, except if the app has IAP – support for IAP is being investigated for the future.

    • Replace Xamarin.Forms Xaml syntax with latest UWP Xaml

      Now that Microsoft has bought Xamarin, integrated it in Visual Studio and made it free, it would be awesome to replace Xamarin.Forms Xaml syntax with current UWP so that Devs can benefit from all the new rich features such as RelativePanel, x:Bind, Adaptive Triggers, Live Visual Tree etc and also no learning curve for Xamarin.Forms-specific naming conventions (e.g StackLayout instead of StackPanel)

        This is great feedback. We are excited about the Xamarin acquisition and the .NET ecosystem around cross-platform apps. We are currently looking at this and similar feedback on how we can improve the experience of working with both Xamarin.Forms and UWP implementations of XAML.

      • 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…

          Thanks folks for the suggestion and the on-going commentary. We’re marking this as ‘under review’ to acknowledge that the team is aware of this request. This is a very complicated/hard item for implementation, and there is a general feel that the new accelerated certification process alleviates much of the need (as an update can be published, for most folks, in less than an hour – rather than in 4 days).

          That being said, continue to weigh in on the comments section.

        • 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.

          • UWP System tray support

            I would like the ability to give my app the ability to be in the system tray.

            In addition, I would like the ability to minimize my app to the system tray as well.

            • MaskedTextBox Control

              The TextBox control is the most used control in a Windows program. It also cause a lot of problem either from QA or the user because of invalid data that was entered. Using a masked control will save a lot of time for the developer and reduce the complaints and bugs

              • Splash screen for UWP apps should be optional

                Currently you have to provide a Splash Screen to get your app to pass the certification kit, which should really be a developer's choice like before.

                Splash screens are evil.

                You don't have to agree with me and all the links above, but at least make it optional.

                  Per Ashish!
                  Happy to report that we are making the splash screen optional via a declaration in the UWP app’s package manifest. Tim Heuer and I talked about this at Build 2017. This is targeted to ship with the Fall Creators Update and we will be testing and tuning the timings via flights to Windows Insiders. To opt in, you simply set the property Optional=“true” on the SplashScreen element in your Package.appxmanifest in your app project. If your app is alive and kicking prior to a TBD timeout value, then users don’t see the splash screen. Otherwise they do.

                • Arbitrary background tasks

                  Save for a few narrow use cases, apps are prevented from working in the background (the current backgroundtask has too many resource constraints (http://msdn.microsoft.com/en-us/library/windows/apps/xaml/hh977056.aspx#Background_task_resource_constraints) to be useful).
                  This effectively makes creating entire classes of applications (file archiver, video transcoder, ftp/irc clients, to name just a few) impossible.

                  I understand power consumption is a consideration, but a more balanced middle ground, like only allowing more intensive background tasks when the system is plugged in and/or giving users clear indications such activity is occurring (liek Android does in its notification bar) so that they know why battery life is being…

                    • App Hub登録審査に日本人、もしくは日本文化に精通している人を少なくとも一人は配置してほしい

                      ここのところアプリ登録が増えているせいか、無碍な理由でApp Hub審査落ちして一週間無駄にした、というような話をよく耳にするようになってきました。

                      例:
                      アルファベット混じりのアプリが複数言語混在問題で審査に落ちる
                      http://social.msdn.microsoft.com/Forums/ja-JP/wpmarketplaceja/thread/ccc0be72-9eb9-4853-9aeb-e4bbdaf3aa87

                      日本でWPが出荷される前ならまだしも、もし本気で日本語Marketplaceを運営する気があるのならば、もしWindows Phoneを日本のマジョリティに普及させる気があるのならば、絶対に必要な条件だと思います。

                      別件ですがW-8BENの登録手続きに関しても同様の問題があると思います。

                      • Make it harder to decompile sources from appx packages

                        Windows Phone Silvelight XAPs were signed, so anyone donwloading them through the Store (manual download) could not have easy access to the sources of the app.

                        Now with Universal apps / WinRT (.appx), our binaries are not longer signed as a whole, any script kiddie can unzip and decompile any app.

                        That's a huge problem regarding developer investing on the platform.

                        • Picture Cropping control

                          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. This would allow for Picture cropping.

                            Me and two friends of mine created an app that won in a Windows Hackathon held by Microsoft Cyprus. We actually won the Hackathon without finishing our app due to limitations of Windows phone API. We need some sort of API to automatically send an SMS. The reason for it to be automatic is because this is for cases when the owner of the phone is unable (asleep or something similar) to do so. If you are concerned about security reasons a good implementation of this API would be to always notify the user that a message from that application…

                            • 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.

                                • Add support for 'XmlnsDefinitionAttribute'

                                  XmlnsDefinitionAttribute is an absolutely great attribute for Control Library developers. It allows the developers of that control library to greatly simplify the xaml by reducing the number of XMLNS declarations they need.
                                  The only way around this is for the control vendor to throw every single class that might be used in XAML (not just controls but other types too), in the same namespace, creating a very ugly unwieldy API to code against.

                                  If you use a 3rd party control library or you're a control library vendor, you should vote for this. It'll save you a lot of typing, looking…

                                  • Allow users with the developer role to create app packages in Visual Studio

                                    It's great that the Dev Center now allows multiple users to access the same account, and I can submit app packages as a user with the developer role: https://msdn.microsoft.com/library/windows/apps/mt489008.aspx.

                                    However, it would be even better if it allowed users with the developer role to create app packages in Visual Studio. At the moment, it is impractical for me as a developer to keep asking my boss for his Microsoft account just to create app packages.

                                    • 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.

                                      • ScrollViewer overpan API

                                        Currently when you overpan a ScrollViewer, where's no way to tell how much negative offset it is unless you do hacks like calculating it every 50ms via a Timer.

                                        This will make interesting actions like 'Pull to Refresh' very hard to implement.

                                        Would be nice to have an event to listen to this with a OverpanOffset property or something.

                                        • Convert an individual account into a company one

                                          I started as a sole developer, and now there's a group of us, and we are registered as a business with IRS. I would like to be able to convert my individual account in the Marketplace into a company one without losing my publisher name, my brand, my app portfolio and my user base. It is a common scenario in the "real" world, so why should it be impossible in the Marketplace?

                                            Starting this month apps can be transferred from one account to another. To start the process you need to open a support ticket to start the process. Once you submit the request, you’ll get a checklist (for example you need to finish any pending submissions, export the reports). The acquisitions, reviews history and users are transferred, though the historical revenue is not transferred. The feature is available to every app, except if the app has IAP – support for IAP is being investigated for the future.

                                            So this feature does not convert one account to another type, but allows a developer to create a company account and then transfer apps from an individual account to the new company Dev Center account.
