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 (developer portal, back-end services, reporting/analytics and process)
  • Microsoft Store

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:

  • Windows:
  • Documentation on docs.microsoft.com
    • Sign in to give documentation feedback via Github
  • Visual Studio / .NET

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. lsof and netstat not working (missing /proc/net/tcp)

    I believe there is progress coming way for this issue already but I want to post it just to show my desire for it.

    I am attempting to use lsof to find an open port for an application but rather it returns "sock: can't identify protocol". This occurs because /proc/net/tcp is empty and thus the socket cannot be identified as TCP.

    • WebAuthenticationBroker should use Edge as IE is going out of support

      WebAuthenticationBroker is becoming obsolete as websites like GitHub are dropping support of the IE browser.

      • Closing StreamSocket should stop all pending asynchronous operations

        Closing the StreamSocket (by disposing/deleting it) should stop all the pending asynchronous operations, reads or writes. It used to do this in Windows 8 and early Windows 10 versions but this apparently changed a while ago.

        See https://social.msdn.microsoft.com/Forums/en-US/042569f1-d7c2-4577-b435-024ab0e09061/interrupting-storeasync-stream-socket-call?forum=wpdevelop

        • Add SOCK_SEQPACKET and SOCK_DGRAM to AF_UNIX

          Following the comments on the blog post for AF_UNIX, it would be nice to see SOCK_SEQPACKET and/or SOCK_DGRAM support.

          https://blogs.msdn.microsoft.com/commandline/2017/12/19/af_unix-comes-to-windows/

          Having SOCK_SEQPACKET would remove the burden of distinguishing between independent messages from the user. It also allows greater compatibility for existing POSIX-compatible applications, as was the original goal for implementing AF_UNIX.

          This would be comparable to the "message" mode of Windows named pipes, making AF_UNIX sockets a more complete replacement.

          • AF_UNIX

            We are developing components on Linux which has dedicated system call and memory requests. (AF_UNIX, ANCILLARY, MMAP, and many others ) within Docker. This would signify communication and access on the file system. will be possible to share the roadmap on the LCOW improvment ?
            Thanks

            • StreamSocket connection status

              The StreamSocket class has no good way of polling the connection status without sending data (your connection may have died minutes ago, but you won't know until you try to send something which isn't desirable). Many of the old implementations in .Net and even in VB6 socket control had this functionality (and it was highly useful).

              The proposal is to add something like:

              if (socket.status != ConnectionStatus.Connected)
              {
              // Something happened, update your UI or run your business logic
              }

                    • C# API to determine how "congested" or "slow" a TCP connection is

                      We live in a connected world. And I have a connected app that benefits from fast, low latency networks, but can work with a larger buffer, if need be.

                      It would be really cool if I could open a TCP/IP socket, and by listening to the raw transmissions and re-send events, determine how "good" the network quality is.

                      It would be even better if I could have an API that could make the calculations for me, and offer up a packet failure/retransmission percent, or average time between send and acknowledgment.

                      • Allow to clear BackgroundDownloader's headers

                        Currently the only way to set BackgroundDownloader's header is by SetHeader method, unfortunately once you set the heder value, you cannot clear it as the method:

                        >This method allows the caller to set request headers. This method can be called multiple times for the same header. The values will then be concatenated.

                        The problem comes when we want to create multiple downloads with one downloader, if the server requires to send request via headers, we are not able to downloaded files/items within one downloader, every item requires to create a new downloader instance with new headers. Of course in that…

                            • Provide mechanism to programatically access HTTP.sys failed request data and perf counters

                              HTTP.sys serves as the kernel component backing IIS and the .NET HttpListener. As such, it plays a critical role as the first system to process each incoming HTTP request, but it is unfortunately lacking in diagnostics.

                              There are a number of failure cases, such as a high incoming request rate filling the request queue, that can result in the module rejecting incoming requests directly without handing them off to callers higher on the stack. This leaves the application unaware that it it experiencing such problems.

                              Information about these failed requests is currently only visible via the HTTPERR log file and…

                                Simple usage of the DNS-SD API results in the DNS Client service crashing.

                                0. Set up a UWP shell app to test within
                                1. Do the minimum to create an instance of a TCP service and add a text attribute with a key-value pair

                                ...
                                _service.TextAttributes.Add("CPath", "spConn");
                                ...
                                await _service.RegisterStreamSocketListenerAsync(_listener);

                                2. Note when executed, DNS Client service crashes
                                3. Comment out the TextAttributes line and note service does not crash

                                • StreamSocketControl should include TCP timestamp option support

                                  Think about the future fiber network speed, the upcoming 5G cellular network, ultra fast network is coming. But the modern WinRT network API which is based around StreamSocket, and the corresponding StreamSocketControl do not provide an option to enable TCP timestamps support. Which is not future-proof.
                                  Yes, I know if we're C++ developers, we can use the traditional Winsock API, setsockopt() can do what we need, but that will tied us to the old self-manage threads model, which is not pleasing.

                                  So, please add TCP timestamps option support to the StreamSocketControl class.

                                  RFC7323 tells the story in much greater detail.

                                  • SSL Pining in windows universal apps

                                    Currently I have to do a request to the server to check the certificates, extract the public Key and verify it's ok. Currently I cannot access the handshake of the HttpClient where the SSL pinning verification should be done. I know I can get server certificates from the server once the request is done, but it should have to be done just before sending the info in the SAME request.

                                      • [UWP] Need http proxy function

                                        While http proxy function lost since windows phone,
                                        Now in UWP we can only set http proxy(ip+port,username+psw) in the connected Wifi manually.

                                        We need set it in codes.

                                        Thanks,
                                        Jimmy (win10app@outlook.com)

                                          From Sidharth:
                                          This idea tracks allowing apps to set a custom system proxy for specific HTTP requests. Today, in the UWP platform, the system proxy gets used by default and apps have the option of not going through the proxy.

                                          If you have a scenario that depends on being able to set your own custom proxy from within a UWP app, please add your vote and add a comment with your scenario. Thanks!

                                          Currently Windows OS decides the best Internet connection and uses it automatically (If I have more than one connection like WiFi and Network cable).
                                          Need user setting option to override the same and assign one or more app to use specific network connection (WiFi) and others to use other possible network connection (3g/4g).
                                          This way the already paid for (3g/4g, WiFi, Network cable, etc.) or for that matter I can take more than one provider's internet with variable speeds at home and connect to one PC and use it optimally/efficiently.
