有人可以分享用F#编写的最小工作ASP.NET核心应用程序项目吗？
要在C#中实现最小的演示，我们必须执行以下操作：
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"
}
}
}
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中：
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();
}
}
}
解决方法
我最近一直在探索新的.net核心并面临同样的问题。实际上，这很容易做到。
将F#运行时引用添加到project.json中：
{
"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"
]
}
},"version": "1.0.0"
}
},"imports": [
"portable-net45+win8","dnxcore50"
]
}
}
}
然后将下面的代码放入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，定义你的Startup类非常重要，比如Startup()类型不要键入Startup。否则，Kestrel运行时将在启动期间崩溃。
