ASP.NET Core 1.0 F# 项目 [英] ASP.NET Core 1.0 F# project

问题描述

有人可以分享用 F# 编写的最小工作 ASP.NET Core 应用程序项目吗?

Could someone please share minimum working ASP.NET Core application project written in F#?

要在 C# 中实现一个最小的演示，我们必须执行以下操作:

To implement a minimal demo in C#, we have to do the following:

mkdir aspnetcoreapp
cd aspnetcoreapp
dotnet new

然后编辑project.json:

{
  "version": "1.0.0-*",
  "buildOptions": {
    "debugType": "portable",
    "emitEntryPoint": true
  },
  "dependencies": {},
  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0"
        },
        "Microsoft.AspNetCore.Server.Kestrel": "1.0.0"
      },
      "imports": "dnxcore50"
    }
  }
}

然后执行dotnet restore并使用以下代码:

Then perform dotnet restore and use the follwoing code:

Startup.cs:

using System;
using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.AspNetCore.Http;

namespace aspnetcoreapp
{
    public class Startup
    {
        public void Configure(IApplicationBuilder app)
        {
            app.Run(context =>
            {
                return context.Response.WriteAsync("Hello from ASP.NET Core!");
            });
        }
    }
}

Program.cs:

using System;
using Microsoft.AspNetCore.Hosting;

namespace aspnetcoreapp
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseKestrel()
                .UseStartup<Startup>()
                .Build();

            host.Run();
        }
    }
}

然后执行dotnet run.谁能给我一个提示，如何在 F# 中做同样的事情?

Then perform dotnet run. Could anybody give me a hint how to do the same thing in F#?

推荐答案

我最近一直在探索新的 .net 核心并面临同样的问题.其实，这很容易做到.

I have been exploring new .net core recently and faced the same question. Actually, it's quite easy to do that.

将 F# 运行时引用添加到您的 project.json:

Add F# runtime references into your project.json:

{
  "version": "1.0.0-*",
  "buildOptions": {
    "emitEntryPoint": true,
    "compilerName": "fsc",
    "compile": "**/*.fs"
  },
  "dependencies": {
    "Microsoft.FSharp.Core.netcore": "1.0.0-alpha-160509",
    "Microsoft.AspNetCore.Server.Kestrel": "1.0.0"
  },
  "tools": {
    "dotnet-compile-fsc": {
      "version": "1.0.0-preview2-*",
      "imports": [
        "dnxcore50",
        "portable-net45+win81",
        "netstandard1.3"
      ]
    }
  },
  "frameworks": {
    "netcoreapp1.0": {
      "dependencies": {
        "Microsoft.NETCore.App": {
          "type": "platform",
          "version": "1.0.0"
        }
      },
      "imports": [
        "portable-net45+win8",
        "dnxcore50"
      ]
    }
  }
}

然后将下面的代码放入您的Program.fs:

Then put code below into your Program.fs:

open System
open Microsoft.AspNetCore.Hosting
open Microsoft.AspNetCore.Builder
open Microsoft.AspNetCore.Hosting
open Microsoft.AspNetCore.Http


type Startup() = 
    member this.Configure(app: IApplicationBuilder) =
      app.Run(fun context -> context.Response.WriteAsync("Hello from ASP.NET Core!"))


[<EntryPoint>]
let main argv = 
    let host = WebHostBuilder().UseKestrel().UseStartup<Startup>().Build()
    host.Run()
    printfn "Server finished!"
    0

顺便说一句，像type Startup()而不是type Startup那样定义你的Startup类是非常重要的.否则 Kestrel 运行时将在启动期间崩溃.

Just by the way, it's very important to define your Startup class like type Startup() not type Startup. Otherwise Kestrel runtime will crash during startup.
