  1. Add virtual extension methods (default interface implementations, default methods, traits) to C#

    C# has extension methods, which allow one to define a method that is syntactically invoked on an instance, but defined as a static method on another type. However, these methods lack one very important feature of normal methods: they cannot be overridden by specific implementations.

    Java 8 in contrast introduced an alternative concept, called virtual extension methods, which could be beneficial for C# as well. Virtual extension methods are defined as interface methods with default implementations:

    public interface IMyInterface
    {
    string Property { get; } // ordinary interface member

    default string Format()
    {
    return string.Format ("{0} ({1})", GetType().Name, Property);
    } …

    • Support .NET Builds without requiring Visual Studio on the server

      To build certain PCL libraries and libraries for Windows 8 RT requires having Visual Studio on the server.

      Nick Berardi writes about a workaround that allows running a build server without VS, but it's really just a workaround for functionality that should be easy.

      Not to mention there's probably licensing considerations we're just ignoring by doing that.

      http://nickberardi.com/a-net-build-server-without-visual-studio/

      Please make it easy (and legal) to build .NET projects on a server without requiring a Visual Studio installation (or license) on that server.

      • Allow build summary to display code coverage percentage based on lines of code

        When code coverage is run as part of a build the percentage displayed in the build summary is calculated based on the number of blocks covered. We would like to be able to configure this to calculate the percentage based on lines of code covered - as we fail the build based on lines of codes covered.

        We have to stick with lines of code rather than code blocks for compatibility with other tools we use.

          • Enable Abstract Syntax Tree Source Files via Roslyn

            Now that Roslyn is available (or will be available), it is time for Visual Studio to start thinking in files that represent Abstract Syntax Trees (ASTs), or .ast files. .ast files are the actual source files that are checked into source control. When an .ast file is loaded into Visual Studio, the developer's "formatting preference configuration" is applied to the .ast file to display the file to the preference of the developer.

            Formatting preference configurations would include things like:
            - Spaces or Tabs for tabbing
            - Braces on same line as method declaration or below
            - Spaces around symbols
            -…

            • Provide support for compile time checks of WPF bindings

              We already have intellisense for the Bindings when setting the design time DataContext on a Window.This however is not enough.

              We also need compile time checking of the bindings. Please provide this.

              • Add trend chart support for tag-based queries

                Trend charts are really useful to track progress against backlogs and bug counts on the home page. It would be great to extend this functionality so trend charts could be built based on tagged work items, for instance to show an overall trend of technical debt stories in a product. Currently when this is attempted the chart pane contains the error message: "Work item trend charts do not support queries conditional on Tag state"

                • Please keep the Reference Source symbol server updated

                  The Reference Source is a very useful feature, particularly so for its ability to step through framework code. But that feature never lasts very long after a release. Many programmers have .NET 4.5.2 on their machine today, the server doesn't supply the necessary PDBs. Downgrading to 4.5.1 is painful and often not possible at all.

                  Please keep the server updated.

                  • Make XAML a first class citizen of Visual Studio

                    Make XAML participate in compile time syntax checking, in code refactoring (e.g. property renames), and in code navigation. Add refactoring (e.g. "Create Style from Element") and other performance features to the XAML code editor (e.g. allow in-place editing of xaml tags so that the end tag changes when you change the begin tag).

                    • Modify CultureData to support PersianCalendar

                      Currently, the windows OS does not return the correct Calendar for "fa-IR" culture, so anytime you create a new CultureInfo instance you end up with a wrong calendar!
                      I couldn't help but notice in the .net reference source there's also a similar issue with the "zh-TW" culture which you have managed to fix when you make reference to CalendarIds property, as you can see here:
                      http://referencesource.microsoft.com/#mscorlib/system/globalization/culturedata.cs,93714edd02838809

                      As mentioned above there's a line of code in culturedata.cs class which fixes ""zh-TW"" culture with Calendar.CAL_TAIWAN
                      I suggest you do the same with PersianCalendar (which is a built-in type within .net framework)

                      • Additional PSRemoting options and package download via HTTP(S)

                        Could you please provide a way to specify the Enter-PSSession options -ConfigurationName, -Port, -Authentication and -CertificateThumbprint, next to the ones that are already available when deploying a component (such as UseCredSSP, SkipCaCheck, etc.)?
                        Especially -ConfigurationName would be welcome, since it would allow admins to create a dedicated PSSessionConfiguration that can be secured appropriately.

                        Also, could you please provide a more firewall-friendly option than file shares to download the deployment package from? Perhaps something like HTTP(s) or SFTP/FTPS downloads.

                        Both features would help in using Release Management in Test/Acceptance/Production environments that are separated from eachother through firewall and/or network routing rules…

                        • Support more than 100 Git repositories

                          Visual Studio has currently a limitation of 100 Git repositories which it can show per team project. Since it is quite common nowadays to have only a single team project this limitation can be reached quite fast.

                          The workaround with manually cloning the repository is also not really satisfying since repositories cloned this way lack of several TFS integration features (eg. linking commits with work items).

                          • 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…

                            • Add configuration variables to Release Template

                              Configuration Variables are nice! But it would have been great to have those in the Release Template "scope"

                              I'd like to define a configuration variable like "LogDirectory" where all my components would inherit instead of settings one variable within all the components of the release template.

                              Needing a different value within all Release Templates, global and server variables are not usefull in this case.

                                  Something like where VS has a "code mode" for code behind or MVVM or other pattern.

                                  If MVVM is selected then the IDE helps us fall into the pit of MVVM success.

                                  Even better would be a coding mode provider model, so other patterns could be plugged in over time

                                    Automatic creation of a Task to Sign a Test Case

                                    Possibility when you sign a Test Case to a tester , automatically create a bond with the Task Test Case and inserting hours for management.

                                    When the task was generated , sought basic information on the title , tester, and enclosing the Test Case, giving option to attach or not the Requirement/PBI.

                                    • Allow ReadOnly Modeling Projects for Premium and Professional versions of Visual Studio

                                      Well, as soon as the ALM Assessment Rangers Workbook has a question in Architecture & Design Spreadsheet asking if all of the team members have access to all the project diagrams, it makes sense that all Visual Studio versions have at least Read Only access to the modeling project.

                                      Nowadays, to accomplish it, I need to manually export the diagrams and publish it on any portal, like Sharepoint.

                                      • Trigger Rollback activity when a Release is Rejected (somehow) by the user/approver

                                        Nowadays, the Rollback activity in the Release Template is triggered only if one of the previous activities fail (returning a non-0 status code).

                                        It would be great to be able to trigger a Rollback activity if the release is Rejected by some of the Approvers.

                                        By now, when it happens, we need to trigger a new Release manually to rollback the application to the previous version. It takes a hard work because we need to find the latest valid (and released) build, etc.

                                        • Allow VSO Stakeholder License to use Feedback Client

                                          Please consider allowing the new VSO Stakeholder license the ability to submit Feedback using the Microsoft Feedback Client. Appears that submitting a new feedback response work item created via the feedback client is not enable for Stakeholder license. User must have basic license.

                                          We want anyone in our organization specifically testers, support people and consultants to be able to capture a bug using the feedback tool and create a TFS item related to it. New stakeholder license seems perfect for this. Appears only "Basic" licensed users can do this.
