  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.

    • Implement 'Compiler as a service' for F#

      It would be a tough blow for F# adoption to not provide 'Compiler as a service' when VB and C# does.

        Our recommendation for Visual F# Tools users requiring a “Compiler as a Service” component is to use and contribute to the F# compiler service component at http://fsharp.github.io/FSharp.Compiler.Service/. This is also available as a Nuget package. This implementation is directly adapted from the open source code for the Visual F# implementation.

        The component is already used by numerous projects including the Visual F# Power Tools, FSharp.Formatting, the Xamarin and Emacs editing bindings for F#.

        We also encourage (and would like to contribute to) discussions about implementing Roslyn interfaces using the functionality available in the FSharp.Compiler.Service project.

      • Improve IntelliSense support for F#

        F# is seriously lacking Intellisense support in VS2010. it would be very nice if it had the same support as C#. The currently available code completion features really make VS feel like notepad.

        • Better code navigation in F#

          Bring over the code navigation features found in the VB.NET/C# Visual Studio experience, such as Find All References and Call Hierarchy

          • Publish the source code of the F# project plugin for Visual Studio

            Similarly to what was done to the compiler, so people can improve the IntelliSense support, add refactorings, etc., instead of asking for those features here

            • floating point optimizations around SSE4, AVX etc

              more and better floating point optimizations around SSE4, AVX etc

              why this is a crucial feature for high performance programming --
              either do it on x86 platform or support CUDA ..,. just to be competitive.

              Is it many/multi-core CPU-GPU or GPU-CPU?

              • Add folders for Visual F# Projects

                Realted to this post: http://stackoverflow.com/questions/5918534/why-cant-i-add-a-subfolder-in-a-f-project

                When using type providers, you ofen need to keep a static file to declare the type. Having a folder where I keep all of these files (versus scattered in my project's main folder) would be very helpful

                • Allow optional naming of union fields

                  It can be hard to keep track of field order, especially when there are several of the same time. For example: type MyUnion = Case1 of string * string * string. It's hard to remember which field is Id, Name, Description, and so on. If the fields could be notated -- type MyUnion = Case1 of Id:string * Name:string * Description:string -- then Intellisense could be provided when entering case constructors.

                  • Include F# support in VS2011 Express

                    Currently with the Win8 Developer Preview VS2011 supports C#, VB.Net and JavaScript in the Express SKU. It would be nice to see F# integrated alongside these.

                    • Support explicit member constraints (duck typing) for records

                      Explicit member constraints are great for reducing the amount of copy & paste code we write, but they're of limited use when you use records regularly, because record fields aren't recognised.

                      See example code: https://gist.github.com/1173248

                      • Support rich debugging of F# scripts

                        F# developers love the low-overhead, iterative REPL experience they have today, but when scripts become larger and more complex, they become difficult to debug. There is no interaction whatsoever today between Editor + F# Interactive and the VS Ddbugger. Thus to debug complex scripts, devs must resort to one of:

                        - `printf` debugging
                        - Create a console app, paste in script code, F5-debug the console app

                        It would be much nicer if we could have the VS debugger participate in the F# script workflow directly.

                        • Highlight variable usage in F#

                          It should be possible to mark all usages of a certain variable. The type of the variable is already inferred and shown when hovering over it. It'd be great if all places where the variable is used are highlighted, e.g. by setting a background color on the variable name. It'd be great if this is possible for several variables.

                            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 in Visual Studio 2012 and 2013.

                            While it is at an early stage, highlighting variable usage is one of the features enabled by this project.

                            The project is seeing significant contribution levels and we encourage community contributions to it.

                            Although this functionality is not yet included in the Visual F# Tools, this item is being closed as “completed” to allow votes to be recycled, and because it also implied by some of the other tooling requests.

                            Possible future paths may include migrating functionality from the Visual F# Power Tools to the Visual F# Tools proper, depending on quality levels and other factors.

                            Don Syme, answering on behalf of the Visual F# Tools Team

                          • More extensive colorization of modules and classes in the editor.

                            Currently, module and class names are not given their own color in the editor and this can make it difficult to look at larger blocks or longer lines of code. Different colors should be used for modules (e.g., the word List in `List.map`), classes/constructors/structs (e.g., DateTime in `let x = new DateTime()` or `let x = DateTime.Now`), and enums (e.g., DayOfWeek in `let x = DayOfWeek.Monday`).

                                Make F# work like C#, where there is more fine-grained control over which frameworks are targeted. Currently it is not possible to use the portable version of Reactive Extensions from a portable F# library due to F# only targeting Profile47.

                                • Create more frequent Visual F# pre-release packages

                                  Now that Visual Studio 2017 is in release candidate, it would be useful if we could get some more frequent releases of the F# vsix package to test out without having to go through a full compiler build on our local machines.

                                      • IDE improvement

                                        F# Depth Colorizer Extension for Visual Studio 2013 [1] offers an entirely different, light years better quality of coding and readability of code in F# and deserves to be part of Visual Studio rather than a separate extension. Please turn the depth-colorizing functionality offered by that extension into a default IDE feature and part of the F# Language Service. The ability to write code that's VERY easy-to-read and understand (available to everyone, even newbie programmers in F#, not only those experienced programmers who downloaded and installed the extension) will have a positive impact on the language popularity and improve the…

                                        • Display parameter names in function tooltip

                                          For example, for the function "let limit low hi value = max (min value hi) low" it is impossible to infer parameter order from tooltip as it displays only types from function signature: " 'a -> 'a -> 'a -> 'a "
