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   When I removed the "ru" language code and published my new version, the old version still remains with "Replaced and unpublished".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…

    • MediaCapture.InitializeAsync - throws unauthorized exception

      It seems that there is a bug, which appeard after the last WP8.1 Update. MediaCapture.InitializeAsync keeps throwing UnathorizedException. I tested it on my previously (before the update) working example and MSDN sample.

      • 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.

        • 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.

          • 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 "

            • 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):

                • 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.

                  • Fix MediaStreamSource in Windows Phone 8.1

                    When creating an app that uses MediaStreamSource to stream audio in Windows Phone 8.0, everything works just great. When porting this app to Windows Phone 8.1, the sound is flickering and its components are "stack overflow"-ing.

                      • Error c101a006 when purchasing in-app product

                        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.

                        • 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…

                          • ApplicationData isn't removed after uninstall windows phone 8

                            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,

                              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…

                              • ucrtbase bug: _wspawnve is broken

                                There is a serious bug in CRT (ucrtbase) which is part of Windows 10.
                                The long story (please read it, since it contains all information about this bug): https://youtrack.jetbrains.com/issue/PY-17069#comment=27-1803709

                                The short story:
                                _wspawnve is broken when launched from Explorer (not cmd) because ``cenvarg.cpp`` expects undocumented environment variable ``=C`` (covered here: https://blogs.msdn.microsoft.com/oldnewthing/20100506-00/?p=14133) and this variable is not provided by Explorer.

                                Tool to reproduce.

                                ```
                                #include<process.h>
                                // Works from cmd.exe, but not from Explorer on Win10 :)
                                void main() {
                                const wchar_t* const args[] = {L"c:\\windows\\system32\\cmd.exe", L"/?", NULL};
                                const wchar_t* const envs[] = { L"FOO=BAR", NULL};
                                int r;

                                • ShellExecuteW w/ symlinks broken on Windows 8.1 and WIndows 10

                                  Hi,

                                  I reported this bug in the "General Windows Desktop Development Issues"
                                  MSDN Forum on 2013-12-05. It got noticed by some guy from Microsoft,
                                  but then nothing else happened. See
                                  https://social.msdn.microsoft.com/Forums/en-US/073d02a6-1181-4694-9e50-d6a05bd80663

                                  This bug is still present in the Windows 10 Technical Preview,but the
                                  below text from my original bug report doesn't explicitly refer to
                                  Windows 10.

                                  In Cygwin we're using the CreateSymbolicLinkW function to create native
                                  symlinks. Preferring a simple code path, we don't make a distinction
                                  between short pathnames < MAX_PATH and long pathnames. All pathnames
                                  given to CreateSymbolicLinkW are long path prefix prepended
                                  (\\?\C:\foo\bar\baz), including the symlink target…

                                  • Fix System.IO.FileNotFoundException when using ToggleButton derivatives!

                                    There is an very old bug that is still present in Windows Phone 8 SDK: when a page has a control that inherits from ToggleButton (for example, CheckBox), System.IO.FileNotFoundException is thrown and shown in the Debug output.

                                    • MediaLibraryExtension SaveSong() forces file extension to .mp3 even for .wma files

                                      .wma files copied/moved to Music library using MediaLibraryExtensions.SaveSong() API from a windows phone app are stored in Music library with .mp3 extension, though the audio file itself will play properly from Music library

                                      When you share it via email - you can notice that file attached has a .mp3 extension

                                      Or connect phone to PC with usb cable and browse through windows explorer to Music folder - you will find the file with .mp3 extension. Manually renaming the file extension to .wma on PC will allow us to play the file properly in Windows Media Player

                                      • Strange behaviour of Pivot inside a SplitView Pane

                                        When you place a Pivot in a SplitView Pane it behaves very strange. Headers don't react to click/touch under certain circumstances, swiping doesn't change the active PivotItem most of the time. The content of the PivotItem seems too wide - wider than the SplitView Pane.
                                        The Pivot behaves normally if I place it inside the SplitView Content though. So as far as I can tell the combination SplitView Pane + Pivot is the cause for this problem.
                                        Why I want to do that? I want to achieve something similar to what Visual Studio Code does in its sidebar. But the…

                                        • Mismatched rendering for xaml pdf printing

                                          From WinRT to UWP, my xaml-generated pdf is not rendering the same.
                                          See below the template of my button and the two different renderings. Correct in pages and designer but not when printing it to a pdf.
                                          Code: http://s3.postimg.org/cttm2rmjn/buttons_code.png
                                          In-app (classic page): http://s3.postimg.org/y27ak710j/buttons_ok.png
                                          Xaml pdf printing: http://s3.postimg.org/52cw47ieb/buttons_nok_pdf.png

                                          Other strange differences did show up as well - especially in Grids - but the example above is the craziest one.
                                          Please tell me if you want some details about other mismatches.
