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. Enable removing language code from the "language history"

    If you ever selected "ru" and "ru-ru" laguages then it causes Tile localization show the en-us(default) tile localization to show.

    When I removed the "ru" language code and published my new version, the old version still remains with "Replaced and unpublished". Wich means the new version not fully replaced the old version.
    And this causes me very serious problems:

    1. Some of my users will still receive the old version of my app (after weeks). The store randomly gives the old or the new version of my app.

    2. My app has a WP7 version and a WP8 version XAP…

    • Background audio problem in W10m build 10586.107

      There seem to be some problems with background audio in the latest build of W10m insider preview.

      The first is that when you develop an app and start playback from foreground UI and suspend the app - the audioplayback will stop along with suspending event. I've tested it on official sample installed on device. One or two my users also reported that it is happening in release mode. This hadn't happened in earlier builds.

      The second thing is that if you set background media player's source as a storage file (not playlist), then start playback from foreground UI, suspend the…

        • PIN should not count as a biometric device for UserConsentVerifier

          The documentation for UserConsentVerifier says that it:

          > Checks for availability of a biometric (fingerprint) verifier device and performs a biometric verification.

          However, if you have a PIN on your system, it treats that as a biometric device as well. This is not what the documentation indicates. UserConsentVerifier should not treat a PIN as a biometric device. It might make sense to have another method alongside RequestVerificationAsync that allows consent verification via PIN or password, but there needs to be a way to request biometric-only consent verification.

          • Unify Splash Screen background color

            When UWP app has a Splash Screen with transparent background color declared in the app manifest, desktop renders the accent color while phone renders the background color. It does not make sense.

            • Fix media pipeline in Windows Phone 8.1

              The media pipeline seems to be broken in Windows Phone 8.1. It seems to have a lot of problems with memory management.

              When creating a background audio app that uses IMediaSource to stream audio in Windows Phone 8.1, the app's components eventually throw OutOfMemoryException and even StackOverflowException under some circumstances. When looking through the memory dumps, there's a lot of uncollected garbage inside.

              Here is a discussion on MSDN forums (see latter posts):

                • InkRecognizer doesn't find any recognizers for windows mobile 10. we need support for mobile

                  I was digging into the new Ink API's and found out that the Inking works well for both PC and Mobile. But then i found out that when trying to recognize what I wrote, on PC it finds the necessary handwriting packages, (en-US etc) when developing we can set a default. For Mobile the API finds nothing and there is no way to download any handwriting packages in the settings. I tried both C# and vb.net

                  • Wallet does have a problem when encoding ">" into Aztec Barcode

                    I have the following entry:
                    <Barcode>
                    <Symbology>AZTEC</Symbology>
                    <Value>M1STURM/ANDREAS EZ5E2PU TXLSTRAB 6531 062Y020A0023 33C&gt;5080 B2A N00 </Value>
                    </Barcode>
                    there you can see the &gt; which is correct XML/HTML encoded version of ">".
                    However when the Barcode is generated, it will generate this code as image:
                    M1STURM/ANDREAS EZ5E2PU TXLSTRAB 6531 062Y020A0023 33C.Taacgpbwnxf +ooooooooooooooooooooooooooooooooooooooov!�
                    As you can see, it fails at the position where the ">" should be.
                    I decoded it using http://zxing.org/w/decode.jspx
                    When I encode "M1STURM/ANDREAS EZ5E2PU TXLSTRAB 6531 062Y020A0023 33C>5080 B2A N00 "
                    using http://www.java4less.com/barcodes/AztecCode/php/demo.php
                    I can then enter the encoded image into the above mentioned decoder and it will decode…

                      • Pubcenter Ads should not play sound unless clicked on

                        Pubcenter Ads should not play sound unless clicked on or have a way to mute ad sounds. Users can't hear content in apps when video ads play automatically and this is extremely distracting to the user to the point where it can make the app unusable.

                              My app has a in-app product, I set its category to Saas and it has English localization. User can purchase it with no problem.
                              Then I add 2 more localized languages.
                              All users cannot purchase it, the error c101a006 occurs again and again.
                              Then I change the category of that product to 'Software download', the error c101a006 disappeared.

                              This is not a individual cases, I found some developers complain it before: http://social.msdn.microsoft.com/Forums/en-US/ad1fcdfc-a964-41d7-a475-8ad6adf70fdf/c101a006-error-in-inapppurchase-for-items-with-full-store-info?forum=wpdevelop

                              The category field of the in-app product is totally useless for both users and developers, I don't know why a useless/descriptive field will cause payment cannot complete.

                              • Bug : SMS Copy-Paste Multiple Recipient Number

                                If you try to copy-paste multiple recipient number to the "To:" box in the messaging, the 2nd until the last number will be duplicated.

                                Step to reproduce:
                                1.) Type multiple number with semi colon separated :
                                For example : 1234;5678;9012;
                                2.) Copy this text, and paste it to the "To:" box in the New Message

                                Expected : 1234;5678;9012;
                                Actual : 1234;5678;5678;9012;9012

                                  I've developed application which targets Windows Phone 8.0. When XAP is deployed on Win10 Mobile device it has some strange bug.
                                  After re-installing the app (uninstall - deploy) Application's Data stays the same - it isn't removed after unstalling the app.
                                  But when I retarget the app to Windows Pone 8.1 problem disappears.
                                  Could you please investigate that?

                                  Regards,
                                  Denis

                                  • Email app crashing upon loading certain code

                                    Hi Microsoft,
                                    I would like to report a bug certain HTML code that causes the Inbox to crash instantly upon viewing the email.

                                    I'm not sure if this can be abused as we've seen on Mango where the phone is non responsive upon receiving a specially crafted text via notification.

                                    Please leave your email so I can sent you the information. I do not wish to leave it out there.

                                    Thanks.

                                    • OnlineIdAuthenticator with CredentialPromptType.RetypeCredentials allows empty password

                                      I'm using the OnlineIdAuthenticator instead of the LiveSDK because it's API references that I would be able to always show a UI to prompt the user to enter their credentials by setting the "CredentialPromptType" to "RetypeCredentials". However, when trying this (ran it on WP 8.1 and WP 10) the user is allowed to leave the password field empty and click on "Save", which then returns them to the app's code to handle the token returned. Because this is SSO for phone, the token is filled in and the app continues like the user had entered their credentials correctly. If I…

                                      • Consider Displaying URL/Location/Context to User in UWP Application During Authentication

                                        (Administrator: I am listing this one as a bug, because I consider it a existing security issue that can be exploited at present, but please feel free to categorize it however you see fit, as always!)

                                        There is what I consider a security issue in UWP applications, that I feel should be addressed. Namely, when the user goes to authenticate their application with a 3rd party authentication provider (e.g. Facebook, Google), the control that is used to handle the process does not display the URL to the user, so they do not know where the content is being loaded from…
