Dev 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 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.

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

    • 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

      • 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.

        • 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…

          • LaunchFileAsync needs to display the application picker if no default program is associated to the extension

            Currently, if we write the following code:

            var answer = await Launcher.LaunchFileAsync(file);

            and if there is no default program associated to the file extension, nothing happens, the answer is true and no application picker is displayed, so impossible for the developer to know if the file has been launched or not

            My idea is: if LauncherOptions.DisplayApplicationPicker is set to false, the platform needs to display the applicaiton picker if there is no default program or return false

            • Pay non-US developers through local MS office to make tax easier

              At the moment, developers planning to sell apps need to have a US tax ID (ITIN, I think?), which can be awkward to get if you're based outside the US. In the AppHub forums, several developers have said that they've paid for certified copies of passports etc to support their applications to the IRS, but are being rejected. Obviously, I'm not keen on starting this process with no guarantee that it will actually work, and I imagine that it's putting off a lot of prospective developers.

              Is it practical to pay non-US developers through a local MS office, so that…

              • Fix push notifications issue

                I've switched to WP recently and found that push notifications on Windows Phone are not reliable at all. (Windows Phone 8.1, Denim).

                I was using Lumia 930 for the last 3 months, and noticed a few occasions where I've missed messages on Viber / FB messenger / IM+Pro: I was not seeing any notifications about new message until I opened Viber / other IM.
                This happens more often when I'm travelling through the areas with poor network coverage (so phone switches to 3G or even 2G for a short periods of time).

                This problem makes WP platform unreliable for apps…

                • Migrating your Windows Phone 8 app to a Windows Runtime XAML app

                  Please create a tool to convert WP8 Silverlight to Runtime app.
                  Create a tool to migrate as much code that is compatible with universal app and mark with the error that is not compatible. This facilitates a basic migration at first then we can concentrate on improving the app for the new interface.

                  • Background Location Tracking in Windows Phone 8.1

                    Windows Phone 8 apps could run in the background. This feature is not available for Silverlight 8.1 apps. MSDN: "If you need this feature, you should continue to use a Windows Phone 8 app".
                    What about all the existing sport tracking apps? How can this apps can be upgraded to WP 8.1? Or is there any workaround to track location in background in WP8.1 (Silverlight/WinRT)?

                    • 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).

                      • 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.

                        • Keep sockets running until app is officially closed

                          I was excited about sockets support until I found out that on every single app I downloaded that use sockets, if I switch to a different app, the start screen, or turn off my phone's display, the socket disconnects. This sucks, for a number of reasons.

                          When switching away from my app, *as long as my app is still in the task switcher*, I want to be able to suspend the UI while maintaining my socket connection (and any necessary base operations required to do so). I don't want to have to reconnect to IRC or SSH or RDP every…

                            Thank you for the suggestion and 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 as we look at continuing to improve the background execution experience for apps.

                            Keep those suggestions and votes coming!

                          • 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!

                              • Improve the Downloads/Sales Reporting UI on App Hub

                                Currently the App Hub provides a very simplistic reporting tool for tracking paid and trial downloads - with a single report row per Trial/Paid type and country. If you have several apps - this can result in several pages worth of data which has to be manually copied and pasted to Excel etc in order to determine totals (which cannot be automated due to https login). Additionally the parent graphs only show total downloads (with no breakdown of trial vs paid totals). There needs to be a proper 'export' to XLS/CSV function for all sales/trial data - as well as…

                                • 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.

                                  • 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。

                                    • ToUpper property on TextBox

                                      Please create this option native to TextBox control
                                      It's very usefull in WinForm projects and could speed up development on universal app too.

On the contrary, in the plight to be distributed (which do not apply the technical regulations conformity certification) devices that do not sell in Japan that do not emit radio waves in Japan to developers, Microsoft Japan will use a device satisfactorily I can not.

And if not, you should consider as…

                                        • Self Signed Certification SSL HTTPS

                                          For those of us wanting to provide free applications it would be nice if the WP7 supported self signed certs or the very least a widely known free SSL authority.

                                          Add ServicePointManager.

                                          Or at the very least add a free service to your accepted list of SSL authorities. Like cacert.org for instance.
