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?

    • PDF/XPS Writer that can generate documents programmatically from UI

      We need a way to save documents generated and populated within our apps to PDF or XPS. Presently the only way to do this is through the print UI (requires user interaction)

      • GattCharacteristicNotificationTrigger enabled for Non-paired devices

        Ability to read BLE responses from non-paired via event notification. This would allow the app to process messages asynchronously without pairing. Some devices/apps do not have the ability of input (pairing/password).

        • Multi-User Fingerprint detection and registration UWP using Windows HELLO

          Im using Windows 10 and VS2017.I have a Finguerprint sensor and Windows hello installed and working fine. It detects finguers. Im now developing a UWP app for multiuser registration using finguerprint. For that propose Im using following part of code:
          var keyCreationResult = await KeyCredentialManager.RequestCreateAsync( ("Peter", KeyCredentialCreationOption.ReplaceExisting);

          The problem I found is that it currently shows a UI dialog asking for current loged in user credentials confirmation. It was suppose to show afther this the Windows Hello Settings page for finguerprint detection( as is in the normal Windows 10 "Windows Hello" Settings page). Afther loged in user confirmation the dialog…

          • Add BackgroundTaskTrigger for NFC tags

            Please add a trigger to start a background task when a nearby NFC tag is recognized. The current options have the current drawbacks for me:
            - To react on a NFC tag my app currently has to start which can be time-consuming and could interupt the user in his current task on another app
            - The NFC tag is currently only recognized when the phone or lock screen is active. It would be more convenient for the user if my app could react on the NFC tag even when the phone is locked.

            • Add reset card method to SmartCard API

              Currently SmartCard API doesn't have any method to force a reader to reset smartcard (Cold Reset or Warm Reset as described in ISO7816-3). It is important as fallback mechanism when the smart card is not responding.

              • read UID on NFC

                Microsoft finally developed a library able to handle NFC devices. Unfortunately the library is only able to get the NDEF messages and doesn't give the UID of the card!
                Is there a reason why this UID is not saved in the Proximity-Device once the NFC card is read?

                    • Expose ISerialDevice Interface

                      In the Windows.Devices.SerialCommunication namespace, there is an `internal` interface named ISerialDevice. I can see it when I "go to definition" on SerialDevice. SerialDevice implements ISerialDevice.

                      In order to break my code's dependency on actual hardware so I could automate my tests, I had to reinvent the wheel. By keeping this interface internal, I was forced to re-create the interface (mostly) and create a wrapper around SerialDevice that implemented it.

                      That's a lot of code to write when the interface already exists. I'm sure making the interface public would save a number of developers a fair amount of effort and frustration.

                      • PIN should not count as a biometric device for UserConsentVerifier

                        The documentation for UserConsentVerifier says that it:

                        > Checks for availability of a biometric (fingerprint) verifier device and performs a biometric verification.

                        However, if you have a PIN on your system, it treats that as a biometric device as well. This is not what the documentation indicates. UserConsentVerifier should not treat a PIN as a biometric device. It might make sense to have another method alongside RequestVerificationAsync that allows consent verification via PIN or password, but there needs to be a way to request biometric-only consent verification.

                            We need to print and see the output of mixed orientation and mixed size documents through WSDA (Windows Store Device App) driver.Please let us know the application list which supports page size with different orientation in Windows 10 Universal Apps. Kindly let us know your feedback whether it is supported in any of the Universal apps or is it a limitation in Universal apps.

                            • Enable setting printer input bin in code

                              In windows forms, it is easy to have users print without a dialog and to code the printer output to use a specific paper bin.

                              This functionality is missing in UWP. One of our applications has users print checks from a shared check printer with the check stock in tray 4. 700+ users as 52 sites do this and it has worked fine in VB6 for the last 16 years.

                              Now that we want to upgrade the applications to a modern environment, we find that UWP does not do it and WPF makes it hard leaving only Winforms.

                                The SmartCard sample (https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/SmartCard) demonstrates how to define a friendly name for a virtual smart card when the virtual smart card is created (see RequestVirtualSmartCardCreationAsync in Scenario1_ProvisionTPM). Unfortunately, neither the SmartCard class nor the SmartCardProvisioning class (nor any other related class) provides a means of retrieving the friendly name later. A getter for this value should be added.

                                    Hello,

                                    My name is Raja from India.
                                    Currently Microsoft doesn't have any specific support for beacons. Beacons are the next generation rulers in the market. As a windows developer, I don't see a good future for windows here,

                                    When ever I contact any manufacturer of beacons, they basically hesitate to support windows, because the limitation in the windows featurest. We don;t have any separate library for beacons. Beacon also considered as normal bluetooth device. Currently I can only read (that too has many limitations) , I can't communicate. This is a big drawback.

                                    We expected this will be solved in…

                                      • Provide a way to disable roaming on a specific PasswordCredential

                                        There are situations in which it's necessary to securely store sensitive credentials but having them roam across devices is undesirable. On iOS, this can be done by creating a keychain item with the attribute kSecAttrAccessibleWhenPasscodeSetThisDeviceOnly. On Windows, there does not appear to be a way to add a PasswordCredential object to the PasswordVault with roaming disabled.
