      Thanks a lot for the feedback. Not only is this happening, it’s also happening in the open! You can follow as we’re making progress on GitHub. You can even participate and help us bringing .NET to Mac OSX and Linux!

    • WeakReference and WeakEvent operators

      //weak reference:
      var value = weak(new Reference());

      //weak event:
      var source = GetLongRunningObject();
      source.PropertyChanged += weak(source_PropertyChanged)

      Or in VB.NET:
      'reference:
      Dim source = Weak(GetReference)

      'event:
      Dim source = GetLongRunningObject();
      AddWeakHandler source.PropertyChanged, AddressOf source_PropertyChanged

      I would surely prefer a symbol operator rather than a verbose one, but I would prefer seeing it in the language

      • Build List, Dictionary and Tuple into the language

        List and Dictionary are used extensively when developing in C# and although Tuple is relatively new it's a very useful class.

        Other languages such as Python and Ruby make these constructs part of the language implementation which makes it incredibly easy to use them and reduces the amount of typing required.

        I would imagine the syntax could look something like this:

        var myList = {1,2,3,4}; // List
        var myDict = {(1,"A"),(2,"B"),(3,"C")}; // Dictionary
        var myTuple = (1,2,3,4) // Tuple

          • Support elastic tab stops

            Support elastic tab stops! Just look at the picture on this web site:

            http://nickgravgaard.com/elastictabstops/

            P.S. we should be able to make the choice between spaces/tabs/elastic tabs on a per-solution (or per-project) basis.

              • Add official support for Blend Extensions

                Currently there is almost no documentation how to extend Blend. I have seen some examples in the wild which seem to be the result of reverseengeneering rather than beeing officialy supported. Some of the suggestions posted here could be easyly programmed by the community.

                [Blend team response]
                In addition to voting for this idea, please leave a comment letting us know what extensions you would like to use in Blend.

                  • Add support for ISupportInitialize on object initializers

                    Quite often, it's necessary to validate an object state when it's initialized. With constructor arguments, this is easy to do as it can be done at the end or begining of ctor code. With object initializers, it's nearly impossible, as there's no way to know programatically when the object initialization is finished.

                    There's a built-in mechamis for this that is being used in WinForms and WPF: the ISupportInitialize interface. The initialization code generated by both toolkits checks to determine if the object implements the interface. If it does, it will call BeginInit() before invoking all property setters, and EndInit() at…

                    • Structure All Nullable Values

                      .NET Framework already has Nullable<T> but it could also have ToNullable<T> as a struct.

                      If you wanted to keep reference-types null and turn value-types to null you could make this:

                      class someGenericClass<T>
                      {
                      T? value; /* = Nullable<T> value; but this gives error
                      because T may already be null */

                      T$ value; /* = ToNullable<T> value; this doesn't give error,
                      what you wnat is keep what's null null,
                      and turn non-null into null */
                      }

                      The only problem is that this does not exist!
                      If you don't understand anything about this, contact jmcf125@gmail.com.

                      • optimize for debugging like gcc -Og

                        An option similar to GCC's -Og would be fantastic for one of Visual Studio's bigger industries, commercial games. One is currently forced between choosing a fully optimized build that is impossible to debug or a debuggable build that can't run many real-time game tests at playable speeds.

                        Some basic optimizations like low-level inlining (simple getters and accessors and other very simple functions) and some math optimization is still easy to debug but can make _massive_ improvements to run-time speed.

                        • Provide a ResourceManager abstraction mechanism

                          The existing System.Resources.ResourceManager is based on .resx files built into a fallback assembly with multiple satellite assemblies. This model works fine for some situations but it is inappropriate for others. It is relatively easy to create custom resource managers but it is not simple to get an application to use the custom resource manager instead of the ResourceManager.

                          What is needed is an abstraction from the 'default' ResourceManager - a mechanism by which I can tell my application to use *my* resource manager instead of System.Resources.ResourceManager.

                          The solution should not be tied to a specific user interface technology. For example…

                                • (Editor) Disable adding a new line after C# [Attributes] when auto-formatting

                                  This thread pretty much says it all >> http://social.msdn.microsoft.com/Forums/vstudio/en-US/9e5dd395-afd7-46d7-845d-5345a3268961/dont-let-the-editor-insert-a-new-line-after-a-c-attribute?forum=visualstudiogeneral <<

                                  What I want is:

                                  Auto format ->

                                  [MyAttribute1] [MyAttribute2] Stuff MyStuff;
                                  [MyAttribute1] OtherStuff MyOtherStuff;

                                  But what I get is:

                                  Auto format ->

                                  [MyAttribute1]
                                  [MyAttribute2]
                                  Stuff MyStuff;

                                  [MyAttribute1]
                                  OtherStuff MyOtherStuff;

                                  which is quite annoying.

                                  There is no option anywhere to disable adding a new line - This should be a very basic built-in option.

                                  Thanks.

                                    • Add Java support to Visual Studio

                                      With Microsoft's recent giant leaps forward into supporting Open Source technologies and platforms, I believe time is ripe for Microsoft to add support to Visual Studio for building Java applications.

                                      History is history - time to move forward: Java is a reality and is very widely used to build server-side technologies in particular.

                                      While IntelliJ is pretty good and Eclipse does it's job, NOTHING comes close to the enormous power and flexibility of Visual Studio and its practically unbeatable editor, window layout mechanisms, debugger, code introspection tooling, etc.

                                      I believe that in adding Java support, Microsoft could expose Visual Studio…

                                        • Add in support for Enum and Delegate constraints

                                          Currently C# disallows constraints for
                                          System.Enum,
                                          System.ValueType,
                                          System.Delegate,
                                          System.Array,
                                          System.Object

                                          However, the CLR has support for classes constrained to All 5 types.
                                          It could be very useful to have this constrain.
                                          To constraint a method to enum we can just use:
                                          where T:struct,Enum
                                          Allowing us to specify only to be called on enum instances and not those boxed as Enum.

                                          Delegate is less strict unfortunately, as there is no way to specify that a T must be an inheritor of a class. A simple solution would be to add an interface to Delegate like `IDelegate` so that we can easily…
