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?

(thinking…)

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. WebAuthenticationBroker in SilentMode does not work on IoT Core

    I'm using WebAuthenticationBroker like this:

    var logoutResult = await WebAuthenticationBroker.AuthenticateAsync(WebAuthenticationOptions.SilentMode, targetUri);

    When I run this on a Windows 10 machine it works as expected and logs out the user. When I run it on IoT Core, it does nothing. If I inspect the WebAuthenticationResult, I see:

    ResponseData: ""
    ResponseErrorDetail: 0
    ResponseStatus: ErrorHttp

    When I listen to the HTTP traffic with Fiddler, I don't even see the request being made when using SilentMode.

    If I change the option to UseHttpPost or UseTitle, it works, but it's a poor UX given the design of our application.

  2. Make WebView Control usable in UWP console app

    Make WebView control or something like it usable in UWP console app. Sometime developers just need to run script to collect the data in the website which doesn't requirement UI.

  4. Creating SeparateProcess WebView in Hyperlink.Click callback crashes the app

    Since Windows 10 RS5 when I try to create WebView Instance with WebViewExecutionMode.SeparateProcess from the Hyperlink.Click callback, the app crashes without any way to capture this exception.
    This worked in Windows 10 RS4.
    See for details: https://twitter.com/martinsuchan/status/1087703946217558016

  5. Please fix the UWP WebView File Upload on Windows 10

    The file selection dialog works just fine when I click on an element displayed in a UWP WebView. However, if I cancel the file upload dialog then come back at it, I am unable to click on the webview element again.

    I posed this question on StackOverflow; so far the there are no conclusive answers: https://stackoverflow.com/questions/53491593/error-clicking-on-element-after-going-to-file-upload-dialog-then-cancelling-imag

    I tested this with WPF's WebBrowser and with the standalone browsers--the interaction turned out fine; I can cancel on the file upload and come back to try uploading it again just fine.

  6. Support JavaScript confirm(), prompt() and alert() methods API in WebView

    The WebView control immediately responds in the negative when a page calls window.confirm(), and with `null` for window.prompt(). There's no apparent way for UWP application developers to implement support for these methods themselves; ScriptNotify can't be used to block JS execution waiting for user input.

    While obviously these APIs are frowned upon in today's day and age, it's a problem when WebView cannot be pointed at an existing web page without causing surprising behaviour.

    Ideally, the Edge browser implementation of these controls would be carried over to apps using the WebView control, but alternatively new events could be created to…

  7. WebGL does not work in WebView in x86 apps on W10 1803

    Our primary UWP app is currently compiled as x86 only because there are some limitations of C++ libs we use.
    We've discovered just today, that WebGL does not work in WebView in UWP apps compiled as x86 on Windows 10 1803.
    Any idea, if this will be fixed in a cummulative update?

  8. Enable Manipulation Events for WebView.

    Since WebView lacks support for Manipulation Events, it acts as a huge gesture eater which doesn't let its parent controls like ScrollViewer, FlipView to take control of gesture like scroll, swipe etc.
    It becomes impossible to use a WebView along with other XAML Elements in the same view.
    Manipulation events can help a lot in these situations.

  9. Print from WebView

    Give us a Print() function for the UWP WebView control. Using WebViewBrush isn't an acceptable response.

  10. Make it possible in WebView to accept invalid certificate for HTTPS website.

    There is currently no way, how to display in WebView HTTPS web page with invalid certificate, even with user specific opt-in.
    It's possible to specify in HttpClient types of invalid certificates to accept, same opt-in should ideally work in WebView as well.

  11. WebView: Expose DOM as C#/.NET API

    It's great to introduce an Edge Browser into a UWP application via the WebView. It would be especially powerful and useful to be able to access the DOM that is in the currently loaded page of the WebView control and have full control over querying it and even modifying it if necessary.

    There have been many DOM APIs created in MSFT's history, so it's now time to build another one. :)

  13. Multiple profiles in WebView

    I have a scenario, when my user wants to sign into two different accounts. Unfortunately, the API does not support that (e.g. it logs off account 1 when logging into account 2). API uses a WebView-based auth.

    It would be great, if I could have two WebView, each having a different user profile.

  14. WebView Context Menu

    It should return DOM element and coordinates, and in case of image also the raw bytes.
    Currently it is impossible to implement context menus, save files, and implement other functions general web browsers have.
    At least, receiving ScriptNotify events should be possible on http and without adding ApplicationContentUriRules in Manifest, so that we could atleast have a way to do it on our own.

    leaving this open as this is a lot of implementation work you have to do.

    Have you looked at the addWebAllowedObject? https://docs.microsoft.com/en-us/uwp/api/windows.ui.xaml.controls.webview#Windows_UI_Xaml_Controls_WebView_AddWebAllowedObject_System_String_System_Object_

    This would allow to be a tool for communication. Eliminates the need to use script notify, is more performant, and enables the communication channel without having to statically declare urls. It also works over http.

  15. Improvements with WebView Rendering Performance

    Comparison results with Edge on the right:
    https://www.youtube.com/watch?v=V4Rrhw15xXI
    Page for testing
    http://output.jsbin.com/surane/quiet
    App tested is WebView, Release.
    Tried both WebViewExecutionMode.SeparateThread and
    WebViewExecutionMode.SameThread
    Even rendering on separate thread will block UI thread (for example "Reveal highlight" effect while bigger page is loading, or typing into TextBox will lag while javascript in the page is running)

  16. WebView cannot login to certain sites

    For example Feedly.com only lets you login via Edge. Apps that use the webview aren't able to login to Feedly.

  20. WebView focus misbehave

    Repro:
    UWP single-page app with WebView as only control. Edge 25.10586.0.0 @ Win10

    When App is activated, WebView control gets focus (and receives corresponding event), but the content of the WebView (eg HTML) does NOT get a focus and document.hasFocus() remains false.

    If user clicks on the HTML, document.hasFocus() becomes true and WebView receives LostFocus event(!)

    Expected behaviour: WebView focus is in sync with document.hasFocus()
