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 (developer portal, back-end services, reporting/analytics and process)
  • Microsoft Store

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:

  • Windows:
  • Documentation on docs.microsoft.com
    • Sign in to give documentation feedback via Github
  • Visual Studio / .NET

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?

    • Allow elevated starupTasks

      I have an always on background Desktop Bridge app, that some users might want to be elevated, when it starts at logon. Add an option to let user do so.

      It might make sense to have that option in Task Manager, since it is the tool to control startup tasks in Windows 10.

      • Allow applications to have elevated privileges/admin rights

        I have a disk imaging application (which I have already converted) that writes bytes directly to disk (USB and SD cards). It requires admin rights to get a lock on the disk. It would be good if we could submit utility tools to the store as there is no way to perform these tasks without admin. Maybe warn the user when downloading the app or more stringent verification process for these apps but don't block them completely as you're hurting both devs and users. There are thousands of apps out there that probably aren't converted for similar reasons.

        • Allow UWP App to access packaged COM if UWP App is packaged in Desktop Bridge

          Packaged COM (https://blogs.windows.com/buildingapps/2017/04/13/com-server-ole-document-support-desktop-bridge/#KgekWJeWFmOwUZRb.97) allows exposing out-of-proc COM objects using desktop bridge, however these COM objects are not accessible from UWP apps, even if the UWP apps are packaged into same desktop bridge exposes the COM objects.

          It is understandable that when UWP app is run normally, it can only access a limited set of COM objects; however if the UWP is packaged to desktop bridge, it makes sense to allow it to access additional COM objects exposed by that desktop bridge, using the technical described in the blog above.

          Without this support, if a desktop bridge contains a…

          • Support for existing UWP Ads in Desktop Bridge applications.

            Currently desktop bridge supports in app purchases. It would be nice if you also ported the ads into UWP APIs so that they can be used with Desktop Bridge apps. As of now, there is no good ad network for existing desktop applications.

            • E_STARTING_ISOLATED_ENV_FAILED with BaseImage 15963

              DesktopAppConverter.ps1 : DesktopAppConverter : error 'E_CREATING_ISOLATED_ENV_FAILED':

              Environment: Windows 10 Pro Version 1603 Build 15063.877
              BaseImage: Windows_InsiderPreview_DAC_15063_1.wim

              So I uninstalled KB4057144, became build 15063.850.
              Re-try desktop app converter was successes.

              I think that it is the problem of baseimage and KB4057144.
              Of course, Version 1709 build 16299.214 can use the DAC.

              • Want to use Desktop Bridge but Windows Store discourages me

                'm writing this feedback in Desktop Bridge because I think this team is the innovative and will do a better job of communicating these problems to Windows Store team. Desktop Bridge attracts me as a developer but Windows Store puts me off. I want to see a better Windows Store first where my apps can be found. Currently, the only way to find programs are if you type their names. There are no keyword searches. For example, type "notes" or "note taking software" and there are no paid programs displayed. This has been like that for many years but no…

                    • Make RequestRestartAsync work in Desktop Bridge application

                      CoreApplication now has a RequestRestartAsync method, but it fails in a Desktop Bridge app with "NotInForeground".

                      Could you add this to the list of UWP APIs supported in Desktop Bridge? I really need to be able to programmatically restart my app.

                      I wonder if this is because of the way the Desktop Bridge technology wraps the WPF application. Any ideas on how I can cause the app to restart?

                        • Where can I report Desktop Bridge issues and get help?

                          Is there some sort of bug tracker for Microsoft software? Kinda like UserVoice but for bug reports?

                          I have an app that works normally, but when launched via the Desktop Bridge there's some strange issues with COM. What does the Desktop Bridge do differently?

                                I tried the converted app using IME. Microsoft IME and JustSystems ATOK work fine. But Google IME launch failed as message is "Launch failed, please system reboot" on Creators Update. Of course, Win32 Apps and UWP Apps can use Goggle IME. We want to improve support Google IME.

                                  • CLASS_NOT_REGISTERED with PackagedCOMServer client app

                                    How can we ensure registration is complete for the COM server without adding regsvr32 command in post build and setting linker value for “Register Output” to false. We can see the entries added in the registry, but client cannot access the interfaces. We see an error CLASS_NOT_REGISTERED message. Saw the same issue with client app in PackagedComServer sample with those 2 settings changed. (removal of regsvr32 in post build, and register output to false).
                                    Link to the sample: https://github.com/Microsoft/DesktopBridgeToUWP-Samples/tree/master/Samples/PackagedComServer

                                    • No sounds with using FullTrustProcessLauncher

                                      I saw new post, and I confirmed that the problem was fixed following URL.

                                      https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/16179244-no-sounds-with-using-fulltrustprocesslauncher

                                      Thanks for fixing an issue.

                                      But, I noticed that it still happens no sound issue in another situation. (Ofcourse, I'm using Windwos 10 Creators Update Version.)

                                      playing sound with System.Media.SoundPlayer in UWP (foreground app) -> calling FullTrustProcess (background task / win32 DirectX app) -> Playing sounds with DirectX in FullTrustProcess -> closing FullTrustProcess -> closing UWP -> rebooting UWP -> (Repeat above for several times) -> No sounds. (neither foreground nor FullTrustProcess)

                                      -> It sounds normally after reboot OS.

                                      Thanks.

                                      • Documentation on how to call UWP API from C

                                        All the documentation on how to call UWP methods are in C# and require the .NET platform.

                                        Is there a low-level C interface as well? I'm developing a Java application so interop with C# is kinda tricky, while interop Shell32 API or C libraries is pretty easy and straightforward with JNA.

                                        • Allow context menu verbs with file explorer integration without having a file type association

                                          On this page, there is explanation how to make a file explorer integration on a desktop bridge app:
                                          https://msdn.microsoft.com/sv-se/windows/uwp/porting/desktop-to-uwp-extensions

                                          In short you could add something like this in your manifest-file:

                                          <uap3:Extension Category="windows.fileTypeAssociation">
                                          <uap3:FileTypeAssociation Name="MyApp">
                                          <uap:SupportedFileTypes>
                                          <uap:FileType MultiSelectModel="Document">.txt</uap:FileType>
                                          <uap:FileType>.foo</uap:FileType>
                                          </uap:SupportedFileTypes>
                                          <uap2:SupportedVerbs>
                                          <uap3:Verb Id="Edit" Parameters="/e &quot;%1&quot;">Edit</uap3:Verb>
                                          <uap3:Verb Id="Print" Parameters="/p &quot;%1&quot;">Print</uap3:Verb>
                                          </uap2:SupportedVerbs>
                                          <uap:Logo>Assets\MyExtensionLogo.png</uap:Logo>
                                          </uap3:FileTypeAssociation>
                                          </uap3:Extension>

                                          I’m working on porting an app that could calculate MD5 checksums on a file. I want to add this as a context menu option on for instance zip and iso-files. But it’s not possible to do this without making a file type association as I get it :(.…
