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. 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…

    • 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)

        In Windows 10 Anniversary Update (Build 14393) we updated Extended Execution Unspecified Reason to be battery aware for PC device family. It is requested in the foreground and if the device is connected to AC power or if it has a battery but the user has set “Always Allowed” in the battery use settings then that app will be able to run without a time limit.

        This works with the single process model as Extended execution does not work with a background task.

        BackgroundMediaPlayback capability also won’t be suspended for certain scenarios.

        We are keeping this open as there is more we can do. If you have scenarios we don’t work well in with the updated models, please tell us!

      • 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.

        • FolderPicker

          Please implement the FolderPicker UWP API on Xbox One. The FilePicker API is supported, but not FolderPicker.

          I am writing a UWP app for Win10, Xbox One, Phone, HoloLens, and require the ability for a user to select one more files (local or OneDrive) to import to isolated storage.

          A user may possibly want to import a few hundred files at a time, all located in a single folder.

          With the current API limitation, I can get the Xbox to display a FilePicker, but realistically a user is not going to select files one by one for a large amount.

            • Emoji control

              Add emoji control to easily render emoji in a page. A single emoji or even a collection of emojis.
              Here is the list of Microsoft emojis : http://emojipedia.org/microsoft/

              Based on an example (http://emojipedia.org/penguin/), the control should handle at least one of these properties :

              * Unicode (ex: U+1F427)
              * Shortcode (ex: :penguin:)
              * Name/Tag (ex: penguin)

              • ViewManagement extension methods

                From a developer’s prespective setting properties for TitleBar / StatusBar require use of code behind as there is no declarative support.

                https://docs.microsoft.com/en-us/uwp/api/Windows.UI.ViewManagement

                We should provide extension such that that would enable developers to set TitleBar and StatusBar from XAML using attachable properties.

                  The existing ConnectionHelper provides a few basic properties that query underlying NetworkInformation class provided by SDK.

                  The ConnectionHelper does not follow best practices or advice as documented on MSDN https://msdn.microsoft.com/en-us/library/windows.networking.connectivity.connectionprofile.getnetworkconnectivitylevel.aspx which state “The GetNetworkConnectivityLevel method may take time in some cases to determine the current value of the network connectivity level. The recommended process for determining the network connectivity level is to register a handler for the NetworkStatusChanged event on the NetworkInformation class. When a notification is received of a network status change, obtain the new connectivity level by calling the GetNetworkConnectivityLevel method on the profile returned by the GetInternetConnectionProfile…

                  • Saturation

                    Add support for changing saturation animation. Would be very useful when you for instance want to convert an image to grayscale. There is already a solution for blur, modifying this for to use saturation would be quite easy.

                    • Support for tables in the MarkdownTextBlock XAML Control

                      The UWP Community Toolkit Sample App contains a page on how to use the MarkdownTextBlock control. The Markdown text used for demonstrating the features contains code for a table, which unfortunately isn't rendered as a table.

                      So the output looks like this:

                      > Reddit has the ability to represent tabular data in fancy-looking tables. For example:
                      > some|header|labels :---|:--:|---: Left-justified|center-justified|right-justified a|b|c d|e|f

                      It would be nice if tables would work.

                          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.

                            • Support for fenced code blocks for the MarkdownTextBlock XAML Control

                              In GitHub Flavored Markdown (GFM), you can create code blocks using triple backticks (```, see https://help.github.com/articles/creating-and-highlighting-code-blocks/)
                              While asking for syntax highlighting may be a bit too much at this point, basic support for the triple backtick syntax would be nice. The GFM language specifier behind the backticks could be ignored in the first iteration.

                                    While I personally appreciate Microsoft's recent improvements involving CP_UTF8 in UoW/conhost, I feel that the support is still far from complete.

                                    Windows' traditional way of making console programs support Unicode characters – compiler-level settings like TCHAR & UNICODE – have been causing troubles for cross-platform libraries and their users. On the other hand, UTF-8, an ASCII-compatible MBCS with support for full Unicode ranges, has become the choice of "legacy-style" C/C++ programmers as well as front-end engineers.

                                    MS is now extending its sphere of influence to many other fields, by introducing open-source programming components and by providing decent cross-platform app-building support.…

                                      Thanks for the suggestion.

                                      The biggest overhaul to the Console’s innards in more than 30 years is currently underway. UTF-8 support is something that we are and will be working on in order to support a much broader set of scenarios, platforms, clients and tools.

                                      Just one example of the level of improvements being made include all the Virtual Terminal sequence support added to the Console during Win10AU to support many *NIX tools, along with the new 24-bit color support we released in today’s Insiders build #14931.

                                      Stay tuned for lots more improvements coming in future insiders and major releases.

                                    • Implement HttpListener Class

                                      Please implement the HttpListener class so that we can run REST based controls (similar to Xbox Smartglass) for our own apps?

                                      • Cannot download files from Device Portal.

                                        This is a bug, not an idea. I'm trying to back up one of my app's database file using device portal (my only option currently) but the save button on the file does not do anything. Please fix it.

                                        • 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…
