Universal Windows Platform

Welcome to the Universal Windows Platform Developer Feedback site. This site provides the Windows developer community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center (dashboard, reporting/analytics, submission process, etc.)
  • Microsoft Store

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

What this forum is not intended to cover or capture:

  • Windows consumer suggestions: Use the Windows Feedback Hub app built directly into Windows 10
  • Documentation on docs.microsoft.com: Sign in at the bottom of the page to give documentation feedback via Github
  • Visual Studio / .NET: Use the Visual Studio UserVoice site

If you’re new to UserVoice, two things to keep in mind are (a) List items (and item rankings) represent community interest in features, and not the 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 (or if too many different ideas are included in one suggestion).

  • Top ideas

  1. SMS Access API

    Please provide an API that provides access to the texts to allow developers to implement an application to enable scenarios such as reading or archiving SMS messages.

    Currently, the platform provides a number of SMS Access from a system eventing perspective (as of Windows Phone 8.1), and Windows Phone supports sms backup/restore for consumers as part of the base OS (Settings → Backup). What we don’t provide is a backup API.

    Using SMS events: Check out the Build 2014 session (http://channel9.msdn.com/Events/Build/2014/2-518) or MSDN docs on background tasks (http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh977056.aspx)

    Although the capabilities are there from a consumer perspective (the core ask for the suggestion), I’m marking this as ‘Under Review’ for the API perspective. The team is aware of the ask and it is something that is being considered.

  2. Custom keyboard via code

    Allow to developers create a custom keyboard. eg. choose letters and numbers together

    Thanks for the suggestion. I’m marking this as under review to note that the teams are aware of this suggestion and that it is under consideration.

  3. Add Iran to Devs Account Registration

    Please , Add Iran to your supported countries list in Developer Account Registration.
    We'll develop great apps for Windows Store.

    We appreciate the interest in Windows 10 and we’re looking into what’s possible. Currently, we don’t have immediate infrastructure to support Iranian developers but we’re investigating solutions.

  4. F# support in .Net native for UWP

    There has been some discussion on the blog post http://blogs.msdn.com/b/dotnet/archive/2015/07/30/universal-windows-apps-in-net.aspx?PageIndex=2#comments for supporting F# in the .Net native toolchain for UWP. I had posted this on the VS uservoice site https://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/7542181-add-f-support-for-net-native but it looks like that was the wrong place to do that. I hope the votes that request got will be considered for this. A lot of people are moving to F# PCLs for library code and to be able to use those PCLs in the UWP and get native compilation via .Net native tools would be great.

    F# team just posted an update on their GitHub. https://github.com/Microsoft/visualfsharp/issues/1096

    This is still a work in progress. One key thing from that post is some of these features and fixes have already been underway for months. While we’ve been investigating F#-specific issues in .NET Native, the team has continued to improve .NET Native. One feature known as “universal shared generics” is likely to have improved .NET Native’s support for F#, even without that being an explicit goal of the feature.

  5. Make Universal Windows Platform Open Source and Cross-Platform

    With the advent of //build 2015, the vision and direction of Microsoft seems to be open source and cross platform. This appears to be the case for every new product from Microsoft except for the Universal Windows Platform.

    It would be great, ideal, and wonderfully awesome to see this platform reach consistency with the rest of the organization and embrace the ideals, values, and benefits from being open source and cross platform like other areas of Microsoft now are (or are on their way to being).

    Please provide consistency throughout the entire Microsoft development ecosystem!

  6. Show a paid app w/ a "trial" option in the "free apps" category

    When I create a paid app with a trial option, many users blow right by it because it doesn't show up in the "free" category even though a light version of the app is free (via the trial).

    Some people are resorting to the super-inefficient Apple app store method of releasing 2 versions of the app... one that shows up in the "free" category and another that runs as a paid app. The "trial" is a fantastic concept, but it is hobbled by this oversight

    Thanks for the suggestion; I’m marking this as under review for implementation in a future release of the Store.

  7. API for Direct phone interaction [dialing, sending/answering, replying/recording, playing to, hooking up/filtering Phone call]

    Without these APIs, PC and Phone are losing features event had existed in pre-internet age and becoming backward.

    When a feature is useful and eases user's pain of doing monotone taping, the security excuse seems a red herring; you can always find a way to do it and there were/are devices could/can do it, why not the Windows Phone, because Apple doesn’t do it?

  8. XAML for live tiles

    Allow developers to implement an interface(s) on a user control and "submit" that instead of just filling in a tile data structure. This will make tiles truly "live" and open up the live of WP7 to new applications. This is also completely secure because the runtime can analyze the class (and it's IL) being submitted. A bevy of restrictions can also be heaped on the said user control in order to maintain performance and not sap battery life. Let Live tiles be live, please.

    It’s great to see that XAML for Live Tiles is so highly requested!

    In Windows 10, we created Adaptive Tile Notifications, which partially addresses this issue. Adaptive is a lightweight XML way to define your tile notification’s appearance. It isn’t as powerful as XAML, and it isn’t animated, but it’s a step in the right direction. The MSN Weather app uses Adaptive to create their rich and beautiful live tile.

    Learn more about Adaptive here: http://blogs.msdn.com/b/tiles_and_toasts/archive/2015/06/30/adaptive-tile-templates-schema-and-documentation.aspx

    In the future, we’ll definitely look at how we can make Live Tiles even better, potentially by supporting XAML. There are performance and other implementation issues, but we definitely understand the need for it.

    Thanks!

  9. Modern Windows UI in Win32 desktop applications

    Bring modern Windows UI to existing Win32, WPF and Windows Forms desktop apps with the option to adopt islands of Windows.UI.Composition and Windows.UI.XAML content incrementally. Allows desktop apps to incrementally adopt UI innovations and creates a bridge to UWP for app UI.

  10. Add a GrantAccountAccessTask for obtaining temporary access to social media accounts

    Social networking APIs, like Facebook, are constantly adding new features. Proving access to the authentication directly (even if it were temporary) would allow applications to use the most up-to-date social networking SDK to provide better features for their users.

    A "GrantAccountAccessTask" could, for example, ask the user for temporary access (including what permissions are needed). If the user did not have an account configured for that provider, they could be given the chance to create one (or simply redirected to the social network providers website).

    Thank you for the suggestion and the spirited commentary. We are not adding this capability in the 8.0 release, but know that it is high on the consideration list for future Windows Phone releases.

  11. Emulate Bad Data Connection - v2.0

    I suggest to create another option that alternates "lost of signal" and "bad signal". Create an infinite loop that breakes the connection in a random time. From 1 to 10 sec, for example.

    A an ability to the emulator that can emulate a bad data connection so we can discover performance problems before our clients receive it. Things like throttling and dropouts

    The new emulators in the Windows Phone 8.1 tooling provide some excellent tools for emulating bad network connections, but there is no option to simulate broken connections

  12. Throttle emulator to hardware specs of phone CPU + GPU

    Create an option to simulate hardware specs like CPU+GPU.
    Dual-core, quad-core, 1.2GHz, 1.5GHz, 2.2GHz, ...
    The emulator is very very fast when I'm using it on my i7 4770. It would be good if we can at least optionally reduce the speed of the emulator to better reproduce real world devices.

  13. Add Markup Extensions to (and Improve) WinRT Xaml System (System.Xaml Parity)

    Much effort was made in WPF Xaml Serialization to decouple it from the presentation assemblies and moved into its own assemblies, System.Xaml, and System.Windows.Markup.

    This Xaml System had it's own serialization/deserialization mechanism in XamlServices class. Furthermore, this Xaml system had a very powerful component/concept that is conspicuously absent in WinRT: Markup Extensions.

    Markup Extensions are found in the following Xaml Systems:
    - WPF
    - Silverlight 5
    - Xamarin.Forms (notably NOT a Microsoft technology, but recognizes their power nonetheless)

    This feature is to ask for Xaml serialization featureset parity with WPF/System.Xaml. That means:
    - Custom Markup Extensions
    - XamlServices.Load and Save …

    An always happy Friday as I just got the TFS complete email :) As this hasn’t hit an insider preview SDK, i’m going to mark this still as “working on it” still BUT … this will be coming to an insider build near you!

    This item heart is markup extensions. There is one item that will not be there however that is relevant to markup extensions, IServiceProvider. I created a new item for that but we are working on this item [https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/19416094-iserviceprovider-for-markup-extensions-for-wpf-par]. We have created a new one and we are working on that (that includes IProvideValueTarget and INameScope) but feel we have enough to ship this and mark this larger work item done and we do point out in reference to more work items need to happen, namely the work around IServiceProvider.

    Also XamlServices.Load / Save isn’t directly related to markup extenstion so we’re viewing that…

  14. 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.

  15. Fight spam/fraud apps more aggresively

    There are several developers using dishonest methods to boost their apps, including fake ratings. Those apps are as good as useless to consumers (cheap website wrappers etc.) and still have dozens of maximum ratings shortly after being released. Those apps get ranked high in the listings and take away the place of the few others that actually are good.

    Reporting usually takes several days or more than one week until something actually happens. Also, I've heard that MS just warns those devs, but even lets them keep obvious fake max ratings. This just makes me angry as a serious developer!

  17. Detect whether user has rated the app or not

    As a developer, the only way to increase app ratings and review is to prompt user.

    At present there are no APIs to detect whether a user has rated the app or not. Some users get annoyed and down rate the app due to this very reason.

    This is a very basic piece of functionality that has been missing for long.

    Please provide us a simple API that gives us this information.

    Alternative for us to continue work towards this http://invokeit.wordpress.com/2013/10/16/detect-whether-user-has-reviewed-your-app-or-not-wpdev/ however I am not keen on this purely because I can see this being abused very easily.

    Per the wonderful Mr. Torr: This should be supported now — if you use StoreRequestHelper.SendRequestAsync and pass 6 and an empty string as the parameters, you should get back a response. (Not documented yet…):

    https://docs.microsoft.com/en-us/uwp/api/Windows.Services.Store.StoreRequestHelper#Windows_Services_Store_StoreRequestHelper_SendRequestAsync_Windows_Services_Store_StoreContext_System_UInt32_System_String_

  18. Provide fix for c101a7d1 when updating, 80004005 when installing, license reset on reinstall

    Microsoft Support recommended me to post the issue here. There seems to be a long-standing serious issue with the Store (or possibly the dev portal) which needs to be addressed urgently. There's a history of apps affected by this issue and possibly more apps to be affected in the future if the issue goes unfixed.

    The problem starts after a certain app update. The symptoms are as stated in the title. Certain users who had installed the app prior to the problematic update are affected. Fresh users are not affected by this issue. While it is possible to reinstall the…

  19. 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.

  20. 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)
