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 support and comment on it.

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

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

  1. Expand Generic Constraints for constructors

    Currently when declaring a generic constraint on a Type parameter
    ie.
    public void DoSomething<T>() where T : new() { /* do something */ }

    You can't specify that T has a constructor with specific parameters:
    ie.
    public void DoSomething<T>() where T : new(string, int) { /* do something */ }

      • Let us create multiple collections on Visual Studio Online

        As an organization with 25+ developers and 15+ ongoing/supported projects for several customers, we need the ability to group our team projects into different project collections.

        I am sure we are not the only ones.

        • Better NullPointerException Error message

          Let's say you have the line

          a.b().c().d().e().f().g();

          and you run it and get an
          System.NullReferenceException: Object reference not set to an instance of an object.

          Where did this happen? what do you need to fix?

          A better error message would be

          The Call: null.e()
          Caused a Null Reference Exception

          this would make debug/life a lot easier.

          I would also suggest you use the full method signature so you might get

          The Call: null.e(string, List<string>)

          • Provide build configuration dependencies in TFS Build

            Provide the ability to create build configuration dependencies such that the success of one build configuration can trigger another build configuration such as a successful build triggering the building of an installation package or a build configuration which deploys to a development or staging server. Other tools such as Cruise Control.Net and Jetbrains TeamCity already offer build configuration dependencies/build configuration triggering through various means, therefore, TFS Build should also provide this type of support.

            • Decrease the Memory Footprint

              Since Visual Studio is a tool which can be used in so many scenarios (desktop development, web development, game development, etc) and supports so many languages (managed, native, scripting) it seems it is often loading tools and editors which are not needed for the current scenario.

              It would be nice to have very fine grain control over what components are loaded at any given time to decrease the memory footprint and increase the performance.

              For example, if I just want to edit a C# file in a class library it seems the memory footprint could be much smaller than when…

              • Make Visual Studio startup and shutdown faster

                Application startup without any solution/project should be instantaneous (less than 1 second)
                Application shutdown should not exceed 100ms for each open project and should show a progress bar.

                  Changed the title to clarify that this is Visual Studio startup/shutdown.

                • Provide a Visual Basic 6 Community edition - to allow free download of the VB6 programming language

                  Make a Visual Basic 6 Community edition free download of the Microsoft VB6 programming language and IDE available.
                  Microsoft already have a VS2013 community edition and also a free download of Expression Web.
                  Now please allow a 'Community Edition' of VB6.

                  • Make the Visual Studio installer more customizable

                    Let one don't install some components if one don't need it - for example Silverlight development support, visual designers for WPF or Windows Forkflow, or unit testing (many developers use third-party solutions like NUnit and don't use VS built-in testing tools).

                    • Merge Wpf and Silverlight to be one framework (that would be called silverlight??)

                      Merge both frameworks to use the same assemblies and controls and make a .net silverlight profile that would be a subset of .net client profile and used by partially trusted xaps.

                      • Allow for updating process templates on existing projects in TFS

                        To keep up with improving processes, there needs to be a migration path for existing templates to be upgraded to new templates. Some information in work items may be lost when mapping these to new work item types of the new templates, but this may well worth the benefits of moving to a newer process. Creating a new team project is not always feasible, especially if the source code versioning needs to be in place.

                              Integration should include:
                              - Authentication - users should be able to use their Office365 accounts and not only LiveID.

                              - SharePoint site integration - from Visual Studio Online let me configure a site that I can host file sharing from, including the ability to use Office 365 as a SharePoint source. Administrative functionality should be included provided the user has the ability to administer Office365.

                              - SharePoint site integration, storyboarding - same…

                                  Currently F# IDE integration into visual studio does not have any refactoring support. It would be nice to at the very least be able to handle renaming.

                                    Update: The Visual F# Power Tools project (http://fsprojects.github.io/FSharpVSPowerTools) is a community-driven project based on the FSharp.Compiler.Service and Fantomas tools. It is available as a Visual Studio gallery entry inn Visual Studio 2012 and 2013.

                                    While it is at an early stage, it contains useful refactoring functionality including some rename refactoring, as well as other functionality, and is seeing significant contribution levels. We encourage community contributions to this project.

                                    This item is being left as “under review”. Possible future paths which could eventually be considered may include migrating functionality from the Visual F# Power Tools to the Visual F# Tools proper, depending on quality levels and other factors.

                                  • Create a MSDN Subscription - Lite version - cheaper and limited tools

                                    Currently all MSDN subscriptions are expensive for individual developers and they provide all s/w that are not really required by individuals.

                                    An individual developer, for hobby, can use express editions of SQL Server, does not need Enterprise editions of OS / Office and similar software that increase the cost of MSDN license.

                                    The suggestion is to create a MSDN Lite subscription that individual developers can buy and will provide tools such as Visual Studio, Expression Studio, Azure

                                    The licensing cost should change little bit-
                                    * For individual developers, the rates should be lower.
                                    * For enterprises, the price can be…

                                    • 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).

                                      • Visual Studio Task Manager

                                        One of the best things about Visual Studio is it's extensibility. The problem is, the more extensions I install, the less stable my Visual Studio gets, the more memory it takes, and sometimes it even takes constant CPU even when minimized. It would be great to have a task manager feature which allowed you to identify the misbehaving extension much easier.
