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. Java SDK to develop Windows apps

    Java is the most used language and the main factor to run Android forward. C# is better but still most developers (more then 40%) like to code in Java because they used to it sinve they started to study Object Oriented Programming in institutions. Making Windows Phone SDK that supports Java and a better documentation will increase apps and games count in the store. You can take example from Microsoft Azure, they are leading in their field as they gives support almost every developer by providing his language support. Be possitive Microsoft, as a Microsoft fanboy since age 6 I…

    • 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…

        • Allow alarms to break through Quiet Hours

          Hello.
          My alarm app which uses alarm-scenario toasts cannot break through Quiet Hours.

          I received plenty, I mean really plenty feedback from users desperately wanting alarms to break through Quiet Hours.

            In the Creators Update (build 15063), all third-party alarm apps (toasts using scenario=“alarm”) will break through quiet hours now, just like the first-party alarm app!

            Thank you everyone for letting us know that this feature was important to you!

          • UWP Windows Always On Top

            Allow an API to cause the window to be always on top. This is great when watching a video while other apps are in full screen. It'll be like Picture in picture (PIP).
            Another use case for this would media player controls so that they are always visible. Also, an application like ColorPic.

              • -PackageName does not accept space, period, hyphen or underscore

                The -PackageName is used to generate both the sub-directory for the output and the Identity in the AppXManifest, but it does not support space, period, hyphen or underscore. According the the documentation it should do https://aka.ms/idname

                  Yes as you stated the PackageName is also used to set the Application Id attribute in the AppxManifest, this is different from the Package Identity and can be found here https://docs.microsoft.com/en-us/uwp/schemas/appxpackage/appxmanifestschema/element-application.

                  Because this attribute cannot take a GUID, in order to specify the -PackageName as a GUID you will need to specify the optional -AppId parameter during conversion.

                  For example: -PackageName “a2e45ad5-dcc3-4683-85ae -b87fbd9301db” -AppId “MyApp” it looks like you have these swapped around.

                  Thanks,
                  Tanaka [MSFT]

                  • Random Hangs in VS15 setup when running using Centennial

                    Hi,
                    I started a VS15 Setup in Centennial, in a VM, and it stopped responding in the middle of the Setup.
                    I got this Line multiple times at the end of the Setup:
                    'Installer is no longer responding.'

                    This doesn't always happen, when I run it multiple times, sometimes it stops responding, sometimes it runs till the end.

                          Centennial: popping out of the container with a new process.

                          I created an app (using the FireGiant appx method) which has the following attribute: The main CPP application launches a secondary process.

                          The secondary process is not running inside the container, but is outside. This was confirmed the following ways:
                          1) It did not have a job object id.
                          2) I replaced the secondary object with a cmd prompt. That cmd prompt could not see the VFS files or registry settings.
                          3) The secondary cmd prompt could start regedit, which elevated using a UAC prompt.

                              Submitted information to Microsoft Bridge. 2 weeks later and no confirmation email or any communication from Microsoft Bridge.

                              How do we get in touch with Microsoft Bridge team to check on status of submission (microsoft support says to try here)?

                              Previously we'd been trying to upload a .appx app to Microsoft App store, and were getting Package Validation Errors which we were told would be solved by submitting to the Microsoft Bridge. They have not yet been solved.

                              Any help would be immensely appreciated!

                                var source = await StorageFile.GetFileFromPathAsync(dialog.FileName);
                                var filename = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyPictures), "Cropped.jpg");
                                using (var outfile = File.Create(filename))
                                {
                                outfile.Close();
                                }
                                var dest = await StorageFile.GetFileFromPathAsync(filename);
                                int width = int.Parse(txtWidth.Text);
                                int height = int.Parse(txtHeight.Text);
                                LaunchUriResult result = await this.CropImageAsync(source, dest, width, height);
                                if…

                                • Desktop to UWP Project doesn't install dependent package dependencies (e.g. CRT)

                                  When deploying a solution involving the Desktop to UWP Project, package dependencies listed in the AppxManifest (such as Microsoft.VCLibs.140.00.Debug) aren't deployed (as is the case with normal UWP projects).

                                  • Lack of documentation surrounding /Extension/Logo element

                                    Context: https://msdn.microsoft.com/windows/uwp/porting/desktop-to-uwp-extensions

                                    Completed example at bottom defines an extension-specific logo but it's not documented. What is it for? What are the metrics for this logo?

                                    • don't show icon asset of context menu

                                      We need to show icon asset with "Open with Program" context menu on Windows Explorer.
                                      I tried to add assets as FileExtension.targetsize-xx.png, then don't show icon assets.
                                      But on ZuneVideo, show icon assets. so ZuneVideo inculde FileExtension.targetsize-xx.png assets.
                                      Why? may be fulltrust apps bug? If so, I want to resolve it.
                                      I want to know how to add file extension assets of "Open with Program" context menu.

                                      • FullTrustProcessLauncher - <desktop:Extensions> give Error C00CE014

                                        Visual StudioEnterprise 2015 Update 2
                                        Universal Windows
                                        Target: Windows 10 Insider Preview (10.0; Build 14332)

                                        I modified the Package.appmanifest like shown in msdn.microsoft.com/en-us/library/windows/apps/mt711589.aspx. Basically just copied the lines from the page into it.

                                        At compilation:
                                        In Package.appxmanifest the line <desktop:Extensions> and <rescap:Capability...> gives warnings.
                                        In AppxManifest.xml <desktop:Extensions> produces this Validation error.

                                        • Help.ShowHelp with chm file

                                          The chm file resides in our installation folder. Help.ShowHelp worked in our desktop application, but not when running in the desktop-app-container. Nothing happens.
