I suggest you ...

You've used all your votes and won't be able to post a new idea, but you can still search and comment on existing ideas.

There are two ways to get more votes:

  • When an admin closes an idea you've voted on, you'll get your votes back from that idea.
  • You can remove your votes from an open idea you support.
  • To see ideas you have already voted on, select the "My feedback" filter and select "My open ideas".
(thinking…)

Enter your idea and we'll search to see if someone has already suggested it.

If a similar idea already exists, you can vote and comment on it.

If it doesn't exist, you can post your idea so others can vote on it.

Enter your idea and we'll search to see if someone has already suggested it.

  1. 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

    • 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.

      • 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…

        • Reduce JIT time with by packaging profiles for non-win8 Store apps

          It is great that I can package my profiles using System.Runtime.ProfileOptimization for Win8 Store Apps (http://support.microsoft.com/kb/2715214). However we need to do it for NON-Win8 Store apps.

          • 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.

                • 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…

                  • 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.

                      • 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...

                        • 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.

                                (also - it would be ideal…

                                • Allow Expression.Assign() to set readonly struct fields as in IL & reflection

                                  Expression trees offer a very good alternative to direct IL generation, they are much easier to write and debug. Yet, for some reason, they attempt to enforce C# language rules instead of allowing the same functionality as reflection and IL.

                                  When deserializing an array of structs T, if the struct contains a readonly field, there are no way to initialize it except through the use of IL or reflection.

                                  Expression.Assign( fieldOfStructInArrayExpression , newValueExpression )
                                  throws ArgumentException "Expression must be writeable"

                                      • Objective-C compiler support in Visual Studio .NET

                                        I am a computer science student and want to try out Objective-C. It isn't always possible to get an Apple Mac to do all the objective-C programming that I am learning. Most of the time I can't get hold of my friend who has a Macintosh as he stays busy. I would like to suggest the idea of including and supporting the objectivc-c compiler in the future releases of Visual Studio .NET if possible. I understand that it is very time consuming job to get the objective-c compiler ready for a windows computer but still I keep the hope of…

                                        • Bring ProgressRing and ProgressIndicator to WPF.

                                          Since ProgressIndicator is just a style template for ProgressBar, there is no reason it shouldn't be accessible in WPF. However I relies on some new animation classes that are only available for WinRT. I would like the new metro controls available to WPF.

                                          So we can build Zune like Metro desktop UIs.
