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).

  • Hot ideas
  • Top ideas

  1. Emulate Bad Data Connection - v2.0

    I suggest to create another option that alternates "lost of signal" and "bad signal". Create an infinite loop that breakes the connection in a random time. From 1 to 10 sec, for example.

    A an ability to the emulator that can emulate a bad data connection so we can discover performance problems before our clients receive it. Things like throttling and dropouts

    The new emulators in the Windows Phone 8.1 tooling provide some excellent tools for emulating bad network connections, but there is no option to simulate broken connections

  2. Throttle emulator to hardware specs of phone CPU + GPU

    Create an option to simulate hardware specs like CPU+GPU.
    Dual-core, quad-core, 1.2GHz, 1.5GHz, 2.2GHz, ...
    The emulator is very very fast when I'm using it on my i7 4770. It would be good if we can at least optionally reduce the speed of the emulator to better reproduce real world devices.

  3. Emulating Camera

    It would be extremely helpful if the emulator could use webcams as camera emulation. Otherwise AR scenarios are hard to develop without a range of devices. It has become even more needed with the addition of WXGA and the different scalings in WP8.

  4. Make the emulator emulate the ARM CPU, like in WinMobile

    Now that native development is an option, it's very frustrating that one can't debug the native code that's being executed on the device without a real device.

    Back in the Windows Mobile/CE days, Microsoft had a Device Emulator that would faithfully emulate an ARM CPU and would execute exactly that same code that eventually went to the device. This capability was essential for certain low-level tasks like native crash investigation, debugging stack clobbering scenarios, deep optimization with inline assembly (e. g. for NEON) and such. Now that capability is lost. Please bring it back.

  5. Please Allow Developers To Test Continuum for Phones on Windows 10 Mobile Emulator

    Developers who do not have access to capable hardware need to have the ability to test Continuum for Phones on the emulator to ensure that the app works as expected. Please allow developers to test Continuum for Phones on the Windows 10 Mobile emulator.

  6. Allow the emulator to simulate phone calls and messages.

    There are several certification requirements from Microsoft that are impossible to test without a physical Windows Phone device. The requirements that involve phone calls, text messages, and zune hub music are all impossible to test from within the emulator.

    It'd be very convenient for developers without actual devices to test their apps for the certification requirements if everything could actually be tested with the emulator.

  7. Screenshot Hotkey in Emulator

    It is physically impossible for me to play my game in the emulator and capture an image of it that actually represents what gameplay looks like.

    My game is controlled by the Accelerometer and has very rapid gameplay that makes switching from using the Accelerometer to Screenshot tab and actually capturing a screenshot impossible. It simply doesn't work. In order to take the screenshot it takes 2 mouse clicks and about half a second. If I am lucky I can do it before my character dies, even then though the player is just moving in a straight line to nowhere…

  8. Media playback on emulator should match Phone

    The phone currently plays a large selection of media formats (MP4, M4V, 3GP etc) that aren't supported in the emulator. This makes apps that use these formats extremely hard to debug.

    Would be awesome if you could fix this :)

  9. Screenshots - all resolutions and languages at once

    Now on Windows Phone 8 when we have 3 resolutions taking screenshots may take a lot of time. You have to run one emulator, take screenshots, close it and run another and so on. We can scale wxga to wvga(it still requires some work), because they have the same ratio, but we can't do this with 720p. Emulators are even slower than the WP7.1 ones, so the process is really long.
    Consider also option where you have application in several languages. You have to take screenshots in one language, change it to another, wait until emulator reloads and so on.…

  11. Ability to manage snapshots in WP emulator

    The Windows Phone emulator should include the ability to manage VM snapshots for Windows Phone images. Developers should be able to create WP images that are tailored to be in a specific state, and manage those image snapshots.

    Hyper-V is a powerful VM management tool, and it includes the ability to create new images and manage snapshots within them, allowing developers to save the current state of the VM (e.g., to manage particular testing scenarios such as upgrading the app when a good amount of custom data is in it, either for one app or multiple) or to roll the…

  12. Emulator IsolatedStorage and State explorer

    The emulator should include a treeview control to display a live view of:

    Page States
    App State
    IsolatedStorageSettings
    IsolatedStorageFile(s)

    The ideal would include some kind of object drill down in the style of Mole for WPF, but even ToStrings would work. This combined with file drag drop from Windows Explorer would make app life cycle debugging a lot simpler.

  13. WP8 Emulator "Demo Mode"

    It would be great to be able to use the WP8 emulator (and Surface emulator for that matter) for mobility demonstrations, i.e. when I deliver a Dynamics CRM demo I often (nearly always) want to include mobility scenarios on the same screen as the rest of the demo. Using the actual hardware is okay for an in-person demo but the form factor isn't ideal to demonstrate the functionality to the whole room. It's no good at all for remote demos.

    The emulators would be a great way to achieve this, but it would require:

    1) The ability to install downloaded…

  14. Enable Emulator usage/Launch without Visual Studio

    This could allow for quite a few scenarios - someone is currently locked in with a carrier that doesn't have WP7 phones available. They could actually purchase apps on the Marketplace and use them.

    Enable a "code-once" and runs on Windows or Phone.

  15. emulator set date and time automatically setting pull from host machine

    If you select the "set date and time autotmatically" setting in the WP emulator, it should sync with the host machine. Too many times when my PC has woken up w/the emulator running the emulator's date/time is stuck from when the PC went to sleep. The incorrect date/time on the emulator can negatively impact external api calls when debugging on theh emulator.

  16. Emulator list management in VS

    Not all developers care about all emulator images that are displayed in the VS list. An developer should have an option or tool to manage that list, and select which ones are displayed.

    Ideally, this tool would show the developer all of the WP emulators on the machine (can be scoped to only those emulators in the standard directory; bonus points if able to add other directories for custom images) and allow the developer to select/check off those emulators that she wants shown int he 'device/emulator' drop-down box within Visual Studio.

    Particularly as the number of optional device images that…

  17. Allow developers to sign into the VS2012 phone emulator with a Microsoft account. Why this is not allowed is beyond me.

    Developers need to be able to use their MS account to sign into the VS2012 phone emulator. If it is a real account I do not see the problem here? We need to be able to test our applications with other windows apps installed. Even if they are only the free apps. Why is this disabled? What is the issue here?

  19. Web debugging via IE11 or VS

    Currently its very hard to debug Hybrid and Webapps. When you create a webview you simply cannot see the DOM or any normal information to see whats going on, what goes wrong and why it goes wrong. Platforms like iOS and Android now feature means to debug your webview via the desktopbrowser. When you connect an iPhone to a mac you can view the webview from Safari by going to Develop->Debug. And voor Android devices you open Chrome and go to "about:devices". This gives webdevelopers a very easy way to debug their applications and to see what goes wrong (and…

  20. Emulator to run on non-SLAT computers

    Just bought a new laptop to develop W8 Phone apps. My processor doesn't support SLAT so it won't run the emulator and get an error msg after installation. Are you guys kidding me???? You're biggest complaint is not enough apps with only 165k compared to 1.5 mil apple & 1 mil android. If you want people to develop apps you need to offer a dev platform that doesn't only run on the latest and greatest machines. You've dumped off you loyal developers to explore other phone platforms.
