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＃编写的最低工作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＃中实现最小演示，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运行。有人可以提示我如何在F＃中执行相同的操作吗？

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，面对同样的问题。

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 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，定义您的Startup类（如 type Startup（）不是 type Startup 。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.
