  1. Web camera control for WPF

    Here in WPF, we still don't have a good way of previewing video and capturing frames from web cameras. Me personally, I have written a C++ library that utilizes Windows Media Foundation, renders a captured sample to IDirect3DSurface9 and sends it back to WPF user control, where this surface becomes a back buffer of D3DImage, but it's not so easy and sometimes is not so fast.

    In Windows RT, we have a CaptureElement and MediaCapture. MediaCapture is available for desktop apps, but CaptureElement is not, so we actually can't use it in desktop WPF apps.

    Since Windows 7 has become…

    • Add a IFormattable to the boolean type

      It would be handy if I could provide a custom format when writing out boolean values.

      I propose this would look like this: "{0:String_If_True:String_If_False}".

      An example in C# would look like this:

      bool result = SomeBoolReturningFunction();
      Console.WriteLine("Result: {0:Success:Fail}", result);

      Same example in VB:

      Dim result as boolean = SomeBoolReturningFunction()
      Console.WriteLine("Result: {0:Success:Fail}", result)

      • Support the -Loopback token in proxy bypass lists

        The .NET Framework is currently hardcoded to bypass the proxy for traffic destined to localhost/127.0.0.1/::1. This makes sense in general, but greatly complicates debugging with Fiddler or other proxies.

        In 2011, this problem was fixed in WinINET and WinHTTP with the introduction of the "minus-loopback" token in proxy bypass lists. When <-loopback> is present, the client should not bypass the proxy for local addresses.

        See http://blogs.msdn.com/b/fiddler/archive/2011/02/10/fiddler-is-better-with-internet-explorer-9.aspx for more detail.

        • Make System.Net.Http referenced by default in new .NET 4.5 projects

          Open Visual Studio 2013 and create a new console project or class library. By default, the project will reference System.Data, System.Data.DataSetExtensions, but not System.Net.Http.

          This makes no sense.

          How is it more likely that I will be working with DataSets than making HTTP requests? This is 2014, not 2004.

          Please update the project templates to reflect the needs of programmers today.

          • Number interface for int,short, double, float, etc...

            Here's the doc's for Linq.Sum : http://msdn.microsoft.com/en-us/library/bb345537.aspx

            It would be nice if there could be just 1 method

            Sum(IEnumerable<Number>)

            For this to happen there would need to be a Number Interface that is common to the number structs (int, short, double, etc)

            I would suggest it includes add, subtract, multiply, divide and asInt, as Double etc....

            I believe this would reduce a lot of duplicate code, plus would allow for expandability with new objects

            • Support System.IO APIs for SkyDrive's Smart Files

              Filed on behalf of our customers.

              As described in this blog post [1], SkyDrive has a notion of smart files [2] which aren't directly accessible using the regular System.IO APIs, such as File.Open. We provided sample code [3] that shows how one can write code that handle smart files correctly.

              But to quote our customer:

              It would be helpful for Microsoft to provide a full blown solution to this which maps all key methods in System.IO such as File.Copy, File.Move etc. to their WinRT API equivalents. This issue is starting to crop up on support forums as it has caught…

                  • Please create a DGML visualizer control that can be incorporated into applications at runtime.

                    It would be very nice to have a control for displaying DGML graphs at runtime for my application. I think it would make a greate UI element.

                    • Adopt IANA Standard Time Zones

                      The .Net BCL TimeZoneInfo class is a wrapper on top of Windows timezone data. Now that ICANN/IANA is formally managing the zoneinfo database (since Oct 14, 2011), Microsoft should favor this standard instead of its proprietary time zone implementation. See http://www.iana.org/time-zones and http://en.wikipedia.org/wiki/Tz_database for further details.

                      This would allow .Net much greater interopability with other Internet platforms.

                      Since Windows timezones have been around for quite some time, Microsoft should provide this as an option, perhaps in a different set of classes, with some translation to and from the existing TimeZoneInfo class for backwards compatibility.

                      • SmtpClient should allow a null MAIL FROM in the SMTP envelope

                        Currently, the behavior of the built-in SmtpClient is to set the SMTP envelope's MAIL FROM as follows:

                        - Use the MailMessage.Sender property if it is not null; otherwise
                        - Use the MailMessage.From property

                        When a .NET application wants to send an auto-response e-mail (such as a "Support Ticket Created" or a "Message Accepted") e-mail, it would be nice to be able to send a null envelope from ("MAIL FROM: <>"). This translates to a "Return-Path: <>" stamp and is the SMTP-sanctioned way to say "I don't want to start an auto-responder war; don't send any bounces back to me."

                        But…

                        • Create [WarningAttribute] that triggers compiler warnings/errors the way [ObsoleteAttribute] does.

                          Add a [WarningAttribute] that works the same way as [ObsoleteAttribute]; it would trigger a compiler warning or error with a customized message. Ideally it would not be sealed. You could do things like:

                          [Warning("This class uses PInvoke and will prevent ARM compatibility.")]

                          [Experimental("This method has not completed Quality Assurance, and should not be used in a production environment.")]
                          This feature would be particularly useful for component creators.

                          This would be the bees' knees.

                          • Adopt dependency injetion patterns in core fx classes

                            Many "core" framework classes (File, ConfigurationManager, ResourceManager, etc) rely on static members to provide their functionalities, making them very hard to mock without the use of isolation framework (such as Moles or TypeMock, which add their own functionality).

                            If the framework just offered interfaces for such classes, injecting them as dependencies would be an easy task and avoid a lot of the hassle with those isolation tools.

                            • Additional overload to System.Concurrent.ConcurrentDictionary GetOrAdd

                              As it stands, the ConcurrentDictionary has a GetOrAdd method that accepts a valueFactory delegate that is not included within the scope of the lock, hence it can be executed multiple times and as a result adding the value to the dictionary and executing the valueFactory is not an atomic operation. This behaviour seems to be misleading in relation to what the API leads one would assume that the benifit of having a method accepting a function overload would be. Let's see an example:

                              For example, the intention of the following code is clear:
                              Object value = ValueFactory(); myConcurrentDictionary.GetOrAdd(key, value)

                                  • Provide support for the new rdrand instruction for use with random number generation.

                                    According to Intel press releases, the Ivy Bridge cpu will incorporate a new hardware random number generator (rng). The cpu instruction to use the new rng is called rdrand. Can you please create a way to use this new instruction from all of the .NET languages (C#, VB.NET, etc.).

                                    It would make the most sense if you provided a way for this instruction to be used as quickly as possible with a simple update and then release a more thorough update that includes functionality in all of the classes that use random numbers sevearl months or years down the road.

                                    • Make VS2012 not hide .NET 4.0 bugs when targeting .NET 4.0

                                      Since .NET 4.5 will overwrite .NET 4.0 assemblies and because you can’t deploy .NET 4.5 on Windows XP and Windows Server 2003 there is a chance that I will not be aware of bugs existing in .NET 4.0 which are fixed in .NET 4.5.

                                      If I target the 4.0 version, bugs may be hidden from me because they are not present in .NET 4.5 which assemblies are used when debugging in VS2012 project targeting .NET 4.0. That means I can’t use VS2012 if I target .NET 4.0 on Windows XP or Windows Server 2003 machines unless I’m prepared to live…

                                      • Multiplatform Framework

                                        We are really bored to write applications only for Windows. You should publish .NET Framework for other platforms. Mono project is not enugh. We need offical .NET Framework package for Linux Distros and OS X. And "build once, run everywhere" option would be good. Like Java's JAR packages...

                                        • Support ICollectionView in Portable Class Library target

                                          Apart from supporting the ICollectionView there needs to be some way of creating a collection view in code for MVVM scenarios.

                                          I guess the approach wich requires the least amount of work from you is to make the PagedCollectionView availible in .NET 4.5 and Metro (if it is not already availible) applications.
