ASP.NET Core 1.0 F# 项目

本文介绍了ASP.NET Core 1.0 F# 项目的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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 核心并面临同样的问题.其实，这很容易做到.

I have been exploring new 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.Corecore": "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.
