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".

      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.

      • XNA 5

        Please continue to work on XNA. It's a great way for indie game developers like myself to make games and give them to the world. XNA gave us the ability to put our games, easily, on the most popular platforms, and to just dump XNA would be therefor heartbreaking... I implore you to keep working on XNA so we C# developers can still make amazing games!

        • API to control screen brightness

          I would like to develop a bedside alarm clock app where the user can control the brightness by touch - so the app can run with the screen off unless the user is touching the screen, or the user can pinch to make the display lighter or darker. All I am able to control at the moment is the contrast of the display (by playing with the colours and alpha levels of the rendered graphics).

          • 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.

              Quick update. We are committed to bringing F# support to .NET Native. The initial version of .NET Native was designed to do a great job of compiling the most popular apps in the Windows Store. Since its launch, we’ve been working on .NET Native support for more advanced .NET IL code, like tail call instructions and complex generic types. These IL features are more common in F# apps than C# apps, and they’re the reasons the F# support isn’t there, yet, in .NET Native.

              Beyond .NET Native, there’s more going on with F# at Microsoft. We’re in the process of bringing F# to .NET Core. We see new teams inside Microsoft adopting F#. We’re excited to see startups considering and adopting F#. And we have an awesome open source community supporting the language and tools. If you’re interested in contributing, join us on…

            • 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

              • 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!

                    Thank you for the commentary thus far. We are not adding this capability into the WPSDK 8.0 tooling release, but know that it is on the consideration list for future Windows Phone releases.

                    As mentioned in the comments, there are a variety of ways of accomplishing access via the included Isolated Storage Explorer and a variety of community tools. Marking this as ‘under review’ to keep it on the tools team radar for improving this experience in the future.

                  • 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.

                      Hi Ananth, we absolutely understand the desirability of this feature. However, our team must carefully balance the power and flexibility that we offer developers, with the consistency and performance of the most prominent screen on the device: Start.

                      We are currently exploring ways to host a light-weight XAML engine in a memory constrained way, but there are a number of technical limitations making this a non-trivial problem. Memory usage on 512 MB devices, resolving ValueConverters that live within an apps’ assembly, exposing storyboards/animations in a consistent/performant way, are just a few examples. We look forward to updating you once we’ve been able to draw a definitive answer!

                    • 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.

                      • 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

                        • 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…

                              • 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!

                                • 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.

                                  • 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.

                                    • Enable Blur and Transparency XAML Effects to Allow for Creative see-through UI designs

                                      The new start menu features the Aero (transparency and blur) effects we all love. It'll be great if we can enhance our own apps with the same effect where we choose. In addition to transparency and blur on any control, give us the ability to apply the effect to the base container, thus making portions of our application see-through to the desktop.

                                      In other words, I want to be able to create designs such as this: http://i.imgur.com/27fUxtM.jpg

                                      Providing more design options, allows us to diversify our application's interface designs and set it apart from others in the market.

                                      • Support for submission packages through API or bulk import

                                        A developer would like to ease the app submission process by being able to upload an app submission as a single archive package per submission. This archive (could be a ZIP file) should contain all of the meta-data (could be as an XML file) and supporting files (e.g., XAP, screenshots, etc.) that the Store team needs to ingest the app and provide it to the store. Apple provides a similar capability via iTunes Connect (https://developer.apple.com/library/mac/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/8_AddingNewApps/AddingNewApps.html).

                                        This capability would not only enhance the submission experience, but it would also allow for Store submissions to be added and tracked in…

                                        • Support SVG elements in XAML

                                          The high-level ask is to support using SVG within a XAML tree. The SVG data may be inline or loaded from a source (local file or remote from the web)

                                          There are few current tools for converting SVG to WPF/Silverlight-based XAML but they fall short when dealing with more complex SVG data.

                                          Here are a few scenarios:

                                          - Apps loading svg content from a remote web server. This should work just like any other kind of image data. Remote xaml isn’t likely allowed, and even if it were, there’d be resistance to providing vector art in two formats when SVG…
