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 refactoring support for F# code.

    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.

    • Improve project F# model

      Improve F# project model (at least, add directions support). Maybe some extension to the language itself would be pretty good: #require "filename" to indicate that filename must be compiled before current file.

      • Support IntelliSense and underlining of errors in F# Interactive

        It's a big annoyance to not have auto completion there. C# Interactive from Roslyn supports it, and even the Immediate pane of C# and VB also have it

                • Split "Solution Explorer" and "Compilation Order"

                  This would allow alphabetically sorted items in the solution explorer, and support for folders in F# projects.

                  Currently, the only way to organize large F# projects is to (artificially) break them down into smaller projects.

                  The codeplex project "fsprojectextender" is a proof of concept.

                      Create collapsible outlines around functions, type declarations, and workflows at minimum, perhaps around more fine-grained constructs as well. Allow mouse-less collapse and expansion with Ctrl+M key.

                          Being able to create F# web project would allow me to use only the VS Shell + F#.

                          The feature set in the full version is quite large and maybe unnecessary. Plus not everyone may be able to afford bigger licences.

                          • F#: Implement a proper expression evaluator in the Visual Studio Debugger

                            I think it is disappointing that F# still (in Visual Studio 11) does not have it's own Expression Evaluator in Visual Studio when debugging.

                            Simple things are annoying like:
                            - not being able to watch, evaluate, or hover over a variable in F# that does not have a valid C# identifier
                            - e.g. someBinding'
                            - or ``The cool string type identifiers``

                            - switching between syntaxes. It may seem sometimes that C# and F# are close enough, but there are some substantial differences. Evaluating an expression from F# code oft needs rewriting before it can be seen in a watch, if…

                            • Provide a standard WPF Project type for F#

                              I have heard that you can do WPF in F#. I have even seen downloadable project extensions for it. Aside from being buggy, they were not as fully featured as their C# counterpart, particularly for the designer.

                              If F# is really a first-class citizen in the .NET world, then it needs to be treated like it. It needs to have a Microsoft standard F# WPF template that works and is fully functional out of the box, just the same as its C# counterpart.

                              • Easier references adding in F# interactive

                                I would like to have easier way to add references (both system and dlls of "my active solution"). Maybe a graphical UI to pick files?
                                Now I have to write manually #r "C:\where was it again\something.dll"

                                I use F# interactive in C# solutions. Just e.g. if I want to check if indexof string can return -1 or not. Now i need to write to "System." to everything (like System.Console.WriteLine).

                                  • F# TypeProviders should work in Windows Store Apps.

                                    F# TypeProviders are not supported in .NET Portable Subset (Windows Store) libraries. The ability to use TypeProviders in a Windows Store app would be extremely beneficial.

                                    • Allow F# code in "Watch" and "Immediate" windows

                                      Currently, if you debug an F# program, you better know C#, or the "Watch" window will be useless to you. I'd like to be able to use F# these windows, for obvious (not so obvious to VS developers...) reasons.

                                        • add code snippet support for F#.

                                          Tired of switching between C# syntax and F# syntax. if can type "type" and tab generate a type for me, or "struct" + tab to give a structure definition, that will make thing much better.
