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".

  1. Provide indexed properties

    For now, we can write indexed properties only for a class like this:
    class A {
    public int this[int index] {...}
    }

    I'd really like to use properties in the following way:
    class A {
    public string foo[int bar] {...}
    }

    • Opensource VS SDK nuget packages

      With the introduction of the official SDK packages (via https://www.nuget.org/profiles/VisualStudioExtensibility), it's become much easier to reference required packages!

      I would like to request opensourcing those nugets, so that contributions could be made.

      I'm sure you are aware of a community effort around VS SDK packages by Sam Harwell, I believe they currently cover a wider API set (as well as supporting versions previous to Visual Studio 2015).

      By opensourcing the official packages and taking contributions, it can will lead to a better, more complete ecosystem.

      • Adding C to Visual Studio

        I think it would be a good idea to add the C language to Visual Studio because it is a powerful language which can be used to create Windows and iOS apps.

        • Implement macro support for output paths (i.e. intermidate and output binaries)

          Simply put: Allow users to redirect where code generated files are stored the way Visual C++ does.
          e.g. Be able to use something like $(VCOutDir)\$(SolutionName)\$(ProjectName)\$(Configuration) to redirect generated binaries to some folder other than where source code is kept.

              • use Android SDK folder "C:\Users\<username>\AppData\Local\Android\sdk" instead of ".\ProgramFiles\.."

                Please use the standard Android SDK install path "C:\Users\<username>\AppData\Local\Android\sdk" instead of installing into ".\ProgramFiles (x86)\Android\android-sdk".

                Thanks!

                • VB Dot Net

                  As like asp.net,In VB allow the showing closing braces for any condition like if,for..etc. for example : when we click on any condition of opening braces then it automatically highlight closing braces for that condition.So we can know the which one is closing for particular opening braces.

                    • Better message for Open Project failure when opening VS Cordova project

                      When trying to open a Cordova project in VS without Cordova installed it would be nice to have a better message than "Can't open Incompatible project". Maybe something like "Cannot open project as Cordova is not installed".

                      • Provide a Macro Visualization Tool

                        Click on a macro and have a window pop-up that shows the expanded version of the macro (the result of the preprocessor). I have to turn on preprocessor output for a single file, compile it, open it, beautify it, and then look for bugs when a "complex" macro is being used. Yes, macros are evil...but sometimes we need a little evil. Why not help the devil out?

                          • C# feature: Allow abstract generic members of a class to be implemented in derived class using covariance

                            To be able to do something like that:

                            public abstract class Base
                            {
                            public abstract List<Base> List {get; set;}
                            }

                            public class Derived : Base
                            {

                            }

                            Right now, if I want to do that I have to do something like that:

                            public abstract class Base<T> where T : Base
                            {

                            }

                            public class Derived : Base<Derived>

                            }

                              • Create a UTF8 C-runtime

                                In the past few years I've worked on cross platform apps, mostly between Windows and linux. The biggest stumbling block are path and file names. In our latest project, it got so clunky, that we decided to drop all the UNICODE code compile the Windows side in MBCS. One thing that would help would be to have a C-runtime which works with UTF8 (also having one that drops the underscores would be another huge help.)

                                  Thank you for your votes so far on this suggestion. We are currently reviewing this request. As we have more information, we will share it with you here. In the meantime, please make sure you comment here to capture the requirements you have for a UTF-8 capable CRT.

                                • C++ Compiler Extensibility

                                  Clang has LibClang which allows some degree of customization of compiler behavior.

                                  It would be greate to havethe possibility to query data and add data to the C++ compiler. This would allow implementations of features like compile time reflection and others by developers.

                                  Now this is only reasonably feasible with Clang/LibaClang.

                                  • Fix the C++11 concurrency implementation to use the Moniker allocator AND dealloactor (and not just one of them)

                                    Up until the last time I checked, the concurrency runtime would use the Moniker allocator and not use it to deallocate memory. This causes issues with some custom memory allocators.

                                    If the C++11 concurrency implementation would use it to allocate AND deallocate, the problem would be solved.

                                    • Xaml nullable properties

                                      Please allow the possiblity of nullable properties in all XAML and not only WPF.

                                      I don't know what the mobile team did with XAML, but it is rather butchered.

                                      I would like to do something simple as this without getting an annoying error like "Cannot assign to nullable type on Property X":
                                      <ControlX Value="0" />

                                      Where the ControlX has a property like this:

                                      public static readonly DependencyProperty ValueProperty = DependencyProperty.Register("Value", typeof(int?), typeof(ControlX),null);

                                      public int? Value
                                      {
                                      get
                                      {
                                      return (int?)this.GetValue(ValueProperty);
                                      }
                                      set
                                      {
                                      this.SetValue(ValueProperty, value);
                                      }
                                      }

                                      • Add the invalid input value to System.FormatException.

                                        It would be nice to see the invalid input value when a System.FormatException is thrown. Currently it shows some generic message exp: "String was not recognized as a valid DateTime etc."
