What Visual Studio 2017 option is required to create an F# ASP.NET Core Web Application?

Question

I have created an F# ASP.NET project in .Net Core by using dotnet new mvc --lang F# .

That works fine but in that setting I don't get built in integration with IIS Express. I have switched over to Visual Studio 2017 because IIS Express debugging is built in and when I try to create a new project the ASP.NET Core Web Application template only shows up under C#. I have installed the F# language support option for Visual Studio 2017 but that did not help. The F# templates do not include ASP.NET Core Web Application.

Is there another option that will enable the creation of ASP.NET Core Web Application with F# in Visual Studio 2017?

Answer 1

Unfortunately, Visual Studio 2017 doesn't yet support F# .NET Core apps. Last I heard, this was targeted for version 15.3, which is still in preview, but I haven't tried out the preview version yet.

The Visual F# Tools project system does not support F# on .NET Core

• The new .fsproj file does not load in VS
• No project system support for package load, cross-platform build, or publish
• No .NET Core templates in-box
• This means you can create something with the .NET CLI and have it fail to load in Visual Studio

Currently there are a number of dotnetcore templates available for F# developers to start with. You can generate the templates and use them in visual studio in the same way you would any other projects\\solutions.

I've had a couple issues with a few on my mac but, they seem to work well enough on windows. https://github.com/dotnet/templating/wiki/Available-templates-for-dotnet-new
