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.
