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?

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".

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. GATT Server API

    Provide a GATT Server funtionality over BLE connection (just like Android >= 4.3) so that devices that work as GATT client can be used with WindowsPhone. For now WindowsPhone 8.1 only provides GATT client.

      Kiran works on the team.

      We published this video for //Build2016 this year – https://channel9.msdn.com/Events/Build/2016/P460

      In it, Kiran talk about how we plan to make unpaired BLE interaction available later this year. GATT Server APIs will be available to developers in that update so please stay tuned! I’ll reply back on this thread when it’s ready but suffice to say we’re hard at working making this happen. Thanks again for your support!

    • Need more info for stack trace

      Now with Win10 Dashboard the stack trace only provide a snippet of the error which is included in the error lines. However with the new dashboard this is the only information that is provided on the dashboard. It's not enough for devs :(

        Can you include in this user voice entry the specific details of what is missing? we are working on improving these reports, and the more specific information we have about issues the more we will be able to add.

      • F# support in .Net native for UWP

        There has been some discussion on the blog post http://blogs.msdn.com/b/dotnet/archive/2015/07/30/universal-windows-apps-in-net.aspx?PageIndex=2#comments for supporting F# in the .Net native toolchain for UWP. I had posted this on the VS uservoice site https://visualstudio.uservoice.com/forums/121579-visual-studio/suggestions/7542181-add-f-support-for-net-native but it looks like that was the wrong place to do that. I hope the votes that request got will be considered for this. A lot of people are moving to F# PCLs for library code and to be able to use those PCLs in the UWP and get native compilation via .Net native tools would be great.

          F# team just posted an update on their GitHub. https://github.com/Microsoft/visualfsharp/issues/1096

          This is still a work in progress. One key thing from that post is some of these features and fixes have already been underway for months. While we’ve been investigating F#-specific issues in .NET Native, the team has continued to improve .NET Native. One feature known as “universal shared generics” is likely to have improved .NET Native’s support for F#, even without that being an explicit goal of the feature.

        • Exclude suspending in desktop

          Some apps can work intensively in background, for example it maybe video converting, online financial data processing and more.
          Now UWP application will suspended when it go offscreen.

          I offer to disable suspending in desktop/tablets for user selection (he can choose 'best performance' or 'power saving' options for example)

          • Allow users with the developer role to create app packages in Visual Studio

            It's great that the Dev Center now allows multiple users to access the same account, and I can submit app packages as a user with the developer role: https://msdn.microsoft.com/library/windows/apps/mt489008.aspx.

            However, it would be even better if it allowed users with the developer role to create app packages in Visual Studio. At the moment, it is impractical for me as a developer to keep asking my boss for his Microsoft account just to create app packages.

              • Are shutdown and reboot features still available in Windows Mobile Device Portal?

                I can't find them after I upgrade my phone to the newest system and I tried to use REST APIs to call the shutdown and restart features but failed either. Will these two features still available in the coming builds or they have already been removed by design?

                  • Fix Map control so that it is possible to databind/add multiple objects in Universal apps with reasonable performance

                    When you add items to the map and then pan the map the items aren't following the map but are lagging behind.

                    If you add more than a few, like 25+ the performance is so bad that you have to wait for a few seconds after you stop to be sure that the pins/controls are in the right position.

                    This is only happening in Universal apps if we make a Silverlight app the pins are following the map like they should even if more than a few hundred items are added.

                    There are lot's of posts about this around the…

                    • Decouple Appium service from app process

                      Today if I want to relaunch the app, it requires killing & restarting WinAppDriver which implicitly launches the target - not only is this at odds with Appium but it creates an uncomfortable dependency between the test code and execution environment that isn't desirable in CI and other "real-world" test situations.

                      • [Bug] Resources broken in a DataTemplate with 14393

                        Using Resources in a DataTemplate worked just fine before.
                        Now that I've upgraded to Anniversary and installed the newest SDK and Tools + the newest Visual Studio Update it doesn't work as expected at all.

                        If I have a datatemplate like this:

                        <DataTemplate x:Key="SomeDataTypeItemTemplate" x:DataType="data:Type">
                        <Grid>
                        <Grid.Resources>
                        <vm:ViewModel x:Key="MyViewModel" Item="{x:Bind}"/>
                        </Grid.Resources>
                        <TextBlock Text="SomeText" Visibility="{Binding IsVisible, Converter={StaticResource VisibleWhenTrueConverter}, Source={StaticResource MyViewModel}">
                        </Grid>
                        </DataTemplate>

                        This will crash on instantiation because somehow the ViewModel object is null when the Bindings are updated which was definitely not the case in previous versions and surely not the expected behavior.

                        If I replace the x:Bind with a…

                        • [Bug] UWP CollectionViewSource in DataTemplate in ResourceDictionary binding breaks

                          - Take a CollectionViewSource in a DataTemplate in a ResourceDictionary
                          - Use that DataTemplate in a page
                          - Navigate to another instance of the same or another page also using the DataTemplate
                          - The CollectionViewSource remains bound to the first page's collection
                          - Navigating to other intermediate pages doesn't affect the result.

                          See https://github.com/ehaskins/UWP-Bug-Reproduction for reproduction.

                                  • Let us draw polygons with holes on the MapControl

                                    Currently, there's a bug where polygons won't render when they overlap themselves (see https://social.msdn.microsoft.com/Forums/windowsapps/en-US/04bf003a-f15d-446a-8f70-3fa96905c303/map-polygons-with-holes-in-windows-phone-81)

                                    So it's currently impossible to draw polygons with holes, which e.g. makes it impossible to draw complex buildings etc.

                                    • Desktop App Converter Stuck waiting for installer process

                                      I'm trying to get Office 2016 packaged so that I can use it w/ ICD as an appx. Right now powershell is hanging at "Waiting for installer process to complete inside Isolated Environment". I saw someone else had posted a similar problem and they didn't have the proper silent switch for their application. I can't seem to find any information online about what the silent switch is for Office 2016. Here is the specific log:

                                        From a technical perspective, Office is a very large and complex installer. Office also currently supports certain features that are not part of the Desktop Bridge in the current release. While you may get some basic scenarios working, you will likely not have all Office features and OS integration points working well.

                                        We will let you know more when we have more information.

                                        Thanks,
                                        Adam Braden [MSFT]

                                        Please provide APIs and support of iBeacons technology and also BLE scanning without pairing just like using "Advertising Package", so that we can exchange data to or from target device.

                                        • 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).

                                            The VC redist packages have just been made available for the Desktop Bridge. You can find more information here:

                                            https://blogs.msdn.microsoft.com/vcblog/2016/07/07/using-visual-c-runtime-in-centennial-project/

                                            We are planning to update the DesktopAppConverter to handle this scenario. Until then, you’ll need to have your setup program install the redist packages as part of your setup.

                                            Hope this helps,
                                            Adam Braden [MSFT]
