  1. Support XAML as a winforms designer

    At compile time, xaml files generate code for instanciating object graphs from the declarative XML syntax.

    It's possible to use that with winforms classes, and the text editor supports fine intellisense in this case.

    We just miss the design surface to display the actual contents.

    XAML file is far easier to edit with a text editor than current code generated by winforms designer.

    It's also easier to figure out the changes in VCS.

      • Allow namespaces to be removed from DataContractSerializer

        The XmlSerializer allows us to remove all XML namespaces from the resulting XML. The DataContractSerializer on the other hand always inserts

        xmlns:i="http://www.w3.org/2001/XMLSchema-instance"

        When integrating with third parties or expecting third parties to integrate with you this can cause major problems on cross-platform calls.

        The DataContractSerializer should allow any and all namespaces to be removed giving full control over the generated XML.

        • Improve compile/link time with C++11 modules

          Clang already supports modules, this reduces the algorithmic complexity of the build while maintaining backwards compatibility.

          This could take a 60mins build down to 10mins.

          • Allow apps to attach HttpMessageHandlers to HttpClient objects created in a referenced library

            Scenario:

            1. Developer writes app A and references library B.
            2. Library B creates an HttpClient object on behalf of the app and uses it to send HTTP requests and receive responses.
            3. App A must have the ability to inspect, log, modify or trace HTTP requests and responses made by C.

            This is not possible today since HttpMessageHandler objects can only be added to an HttpClient object created in the same scope.

            This idea is to:
            Add an API to allow adding an HttpMessageHandler to an HttpClient object created within a referenced library.

              • A Razor Designer the same way we design XAML.

                I'm learning MVC 5 and looking forward I don't even see a designer for the views yet. I don't know the roadmap for MVC but definitely, we need a designer. I feel like the time we wrote Autocad Lisp. Not only we need a designer in Visual Studio but the same way we design the great XAML in Blend which is absolutely fabulous !

                • change the behavoiur for double click on double backtick identifiers to select only a single word

                  If I double click on a word I assume the word gets selected and nothing else. This doesn't work inside of double backticks. It always selects the whole identifier since it doesn't understand that the identifier is a sentence and not a single word.

                  • report templated link errors in a form that can be cut/pasted as explicit template instantiations

                    Right now I find myself taking the linker error (missing symbol), removing the mangled part, editing slightly and creating a specific template instantiation. GCC I believe offers a mechanism to do this.

                    • ContextMenu launched with keyboard should not 'select' a menu item based on a non-moving mouse cursor

                      When a context menu is summoned with the keyboard Menu button, the 'current item' should not be affected by a non-moving mouse cursor which happens to be over one item in the menu. Users with both hands on the keyboard who trigger the context menu with the keyboard expect to be able to up/down from the top of the menu, or to have their hot-keys recognized from top to bottom (eg, a context menu launched in an MVC view has menu items 'view in Browser' and 'Breakpoints' both selectable with 'b').

                        • An effective way to compress Large Object Heap

                          I think I've found an effective way to compress LOH:
                          If CLR always alloc every large object at the beginning of a RAM page(usually 4KB per page),then the large object heap(LOH) can be compressed without much cost: CLR can compress LOH by modifying page table and TLB instead of copying data. If so, small fragmentation maybe still exist (less then a memory page size per fragment), but there would be no large fragmentation, and compressing would be very fast because of not copying large amount of memory data. To do this, OS support may be needed, fortunately Windows OS and…

                          • Integrate NTVS into Visual Studio and/or put more resources into NTVS

                            NTVS is an indispensable part of modern JavaScript development work. At the moment updates to NTVS are few are far between.

                            I would like NTVS to receive the same kind of attention as ASP.net - if not more.

                              • New refactoring: Promote/demote scope ... (for)

                                (I'm not sure if Promote or Demote or something else would be better word)

                                lets say you have
                                Method () {
                                var a=1;
                                Blah();
                                var b=2;
                                var c=1;
                                }

                                then If you select these lines:

                                var a=1;
                                Blah();
                                var b=2;

                                In the refactoring menu there should be option
                                "Promote scope: variable declarations" -this should move the variables from the current scope to the next outer scope:

                                int a;
                                int b;

                                Method () {
                                a=1;
                                Blah();
                                b=2;
                                var c=1;
                                }

                                If the variables were declared inside a while loop, they'd be moved out of the while loop into the next outer…

                                • Allow SuppressMessageAttribute to work types within a namespace

                                  Right now the SuppressMessageAttribute only suppresses diagnostics against a namespace, but not the types within it.
                                  So this:
                                  [assembly: System.Diagnostics.CodeAnalysis.SuppressMessage("Style", "CC0061", Scope = "namespace", Target = "CodeCracker.Test.Design", Justification = "No need for tests to have async sufix.")]

                                  Would not work against types inside the "CodeCracker.Test.Design" namespace, but only if the diagnostic was on the namespace itself.
                                  To be able to do that, we need to add a SuppressMessageAttribute to each type individually, what is error prone, ugly and demands a lot of attention.
                                  There needs to be a way to allow for the suppression of diagnostics agains all types within…

                                      Hey Niklas,

                                      Cool suggestion. We actually do have, or at least had, logos for the .NET languages and stickers bearing them. I have one for VB on one of my laptops and one of each for VB, C#, and F# on another. We used to give these out at conferences and events, I’m not sure if we ran out. At times we’ve also had T-shirts and mugs. Everyone’s always asking us where they can get them. We really should put up a storefront somewhere so that all our fans can show their love. I’ll get on that and let you know what we come up with.

                                      Regards,

                                      Anthony D. Green, Program Manager, Visual Basic, C#, and F# Languages Team

                                      • try-catch "ignore" (or resume, ...) option for catch(ExceptionType) blocks

                                        In catch block, support an option to ignore (i.e. resume code in the try block) for specific exceptions. This suggestion is not tied to any particular syntax. Here are two possibilities:

                                        try
                                        {
                                        A();
                                        B(); // B() will throw OurSystem.SpuriousException
                                        C();
                                        D();
                                        }
                                        catch (OurSystem.SpuriousException X)
                                        {
                                        if (X.SomeProperty == Error.WeDontCare)

                                        ignore; // THIS IS MY SUGGESTION - would resume at "C();"

                                        }
                                        catch (System.Exception ex)
                                        {
                                        // process "ex" - this is a "real" exception
                                        }

                                        or:

                                        try (ignore OurSystem.SpuriousException)
                                        {
                                        // this wouldn't allow any if/else logic, though
                                        }

                                        • Add language extension definitions into c#

                                          Via Roslyn, it is now possible to add language extensions to e.g. C#.
                                          e.g. it's possible to add french quotes to the C# language.

                                          Rather than everyone creating there own compiler to cater for whatever application domain is being modeled, I propose to add this feature into the C# language itself, allowing e.g. straight Math formulas to be programmed into a C# source file through a language extension definition file, using the full Unicode set.

                                          The VS IDE must parse and understand the extensions so that the syntax checker modifies its behavior automatically while the compiler generates adequate .Net code.
