Universal Windows Platform

Welcome to the Universal Windows Platform Developer Feedback site. This site provides the Windows developer community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center (dashboard, reporting/analytics, submission process, etc.)
  • Microsoft Store

Your suggestions will be reviewed by the Windows platform developer team to help with planning ideas and to better understand how developers are using the platform.

What this forum is not intended to cover or capture:

  • Windows consumer suggestions: Use the Windows Feedback Hub app built directly into Windows 10
  • Documentation on docs.microsoft.com: Sign in at the bottom of the page to give documentation feedback via Github
  • Visual Studio / .NET: Use the Visual Studio UserVoice site

If you’re new to UserVoice, two things to keep in mind are (a) List items (and item rankings) represent community interest in features, and not the 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 (or if too many different ideas are included in one suggestion).

How can we improve the Windows dev platform?

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.

  1. Add PaneBackground Property to NavigationView

    It is currently possible to change the background brush of the NavigationView itself, but the Pane, in particular, is not so straightforward. Users can modify the designated ResourceKey, but cannot change this brush outside of XAML.

    Users would benefit greatly from a "PaneBackground" property that can be set to an AcrylicBrush, etc. Especially, since the pane of this control is currently opaque by default in a WPF XAML Island.

    To reproduce this situation, please create an "XAML island" in a WPF application. Setting the child to a NavigationView. Then, from C#, search the NavView object for a simple PaneBackground property.…

    • 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?

      • I need a ClickOnce like Deployment method for my UWP LOB Application

        In my WPF app I created a ClickOnce that I deployed to my Azure website (URL) and warns the user and update the App before it is shown. I need a similar feature for UWP.

        • Enable WinAppDriver for Xbox and Mobile

          Right now WinAppDriver only works on desktop.

          Getting these capabilities across the Windows ecosystem would fulfill the promise of a unified Windows. Making it possible for us to write tests, and code once and have it being tested in an autonomous way. So that in theory, our applications could report and find bugs for us.

          Before our users find them.

          Thanks in advance. Looking forward to the progress you're doing :D

          • Using x:Bind or Binding in a Setter Value property of a VisualState

            Using x:Bind or Binding in a Setter Value property of a VisualState will not be executed at the start of the view, you have to change the state of the and then go back before the bindings are used resulting in initial views being broken.

            • 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 :(.…

              • UI Access support for Centennial Converter

                We have a uwp in the store and a desktop companion app. Currently to install our software (and have it function) both programs are needed. Merging them into a single installer would benefit our users greatly. It seems in order to do that we need to either pull out of the store or convert our desktop app to a uwp and merge the two installers. The issue we run into is that our desktop app uses ui access. Is ui access support on the list of upcoming features? Having a good informed answer to this question will help tremendously in helping us understand how…

                  • Specify Arguments in AppxManifest.xml for Application Executable

                    Many developer will be bringing java / python / etc applications to the Windows Store via the Desktop Bridge.

                    It would be great if the <Application Executable="launcher.exe"> element or the <uap3:Extension Category="windows.appExecutionAlias"> element would allow me to specify arguments in the AppxManifest.xml file.

                    That would allow me to use the bundled javaw.exe or python.exe directly and instead of having to use my own launcher that effectively does nothing but call javaw.exe / python.exe with some predefined arguments.

                    • [Bug] AudioGraph: Gaps and clicks during playback

                      To reproduce you may start with official AudioCreation sample from https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/AudioCreation/cs/AudioCreation
                      Use file playback sample or custom effects sample. Depending on hardware, you may hear gaps right after start or you may need load CPU with some additional work, like scrolling UI or running some work in background threads.
                      I guess it is result of extremely short quantum size (10ms; even switching between threads could take more time) and too low buffer length (2 quants), but it could be just some synchronization issue.

                      • The installed Centennial executable does not know about its installed folders and cannot find them.

                        For example, if in the msi/ appx is added folder, like Samples or Projects, it cannot be found by the open/ save dialogs, with set "Initial Directory", opened by the installed executable, even if the folder is installed in the installed executable's folder. Actually, initially I constructed the msi by placing the folder in the Documents folder, but the Centennial does not install it there, but in the VFS\.... It will be hard for the user to find these kind of folders too.

                          The TextBox control is the most used control in a Windows program. It also cause a lot of problem either from QA or the user because of invalid data that was entered. Using a masked control will save a lot of time for the developer and reduce the complaints and bugs

                            • Allow uiAccess, elevated privs to pave the road for getting rid of MSI

                              Completely separate out UWP from its ties with sandboxing and the windows store. If we look at .appx/the new installation mechanism as a much saner version of app installation, then the more applications it allows, the better. Centennial takes big steps towards that, but I'd like to go even further.

                              My example: An interactive screen sharing app. It requires uiAccess (if I recall correctly, so that it can intercept alt+tab for sending to the remote host) and elevated privileges (so that it can send input events to elevated processes such as regedit, taskmgr, etc for when the remote user has…

                                Please implement possibility for developer to handle (popup) window user flow. This is mainly useful for OAuth 3rd party authentication that is typically not under control of a developer.

                                Today there is a handler for NewWindowRequested to create new window, but there seems to be no way to handle window.close() call from javascript for example.

                                Requesting full implementation of the tools for the case, including support to handle window opening, closing (window.close), window.opener (parenthood) info, messaging (window.postMessage).

                                  • 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.

                                        Thanks for the suggestion. I’m marking this as under review to note that the teams are aware of this suggestion and that it is under consideration.

                                      • Support Multiple Functions for x:Bind

                                        The following example doesn't show an error in the Designer, but throws errors in the generated code. If I add a (x:Int32) case before the inner function I get a 'Functions cannot have other functions as parameters' error.

                                        Width="{x:Bind exf:Bind.Clamp(exf:Bind.Subtract(ContentHolder.(ex:FrameworkElementExtensions.ActualWidth), 30), 100, 300)}"

                                        It'd be great if we could chain functions together in x:Bind to create more complex expressions. The above case is trying to subtract from the width of another element, but clamp it within a specific range.

                                        Rather than writing a specific function for this purpose, it'd be nice if it could be composed of individual pieces that…

                                        • make it possible to declare an OnClick event for live tiles

                                          Make it possible to optionally declare a function OnClick() for live tiles, such that this code is executed when the live tiles is presed without leaving the home screen. Think about WiFi toggles, music controls, unmute/ mute etc.
