在 Windows 服务中托管 ASP.NET CoreHost Core in a Windows Service

1.简单的方法：创建一个 Asp.net 核心MVC项目

1.添加软件包Microsoft.Extensions.Hosting.WindowsServices

2.添加程序.csbuilder.Services.AddWindowsService();

3.将其部署为单个文件并将其注册为 Windows 服务，如下所示，您可以在第 2 节中找到详细步骤。

技巧

如果我们将其部署为 Windows 服务，它将在 kestrel 上运行，最好在代码中定义端口。

        builder.WebHost.ConfigureKestrel(serverOptions =>
        {
            serverOptions.ListenAnyIP(5000); // http
        });

2. 创建 Worker Server 项目

Panagiotis Kanavos的评论是正确的。辅助角色服务项目是 Windows 服务中使用的简化项目模板。

你可以按照我的步骤让 worker 服务支持 mvc 等功能。

1.创建文件夹和文件，如mvc项目

2.添加 .Microsoft.AspNetCore.App

<Project Sdk="Microsoft.NET.Sdk.Worker">

  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <UserSecretsId>dotnet-WorkerService1-d5189c80-2268-4d3c-9c71-bf06594ee612</UserSecretsId>
    <RazorCompileOnPublish>true</RazorCompileOnPublish>
    <RazorCompileOnBuild>true</RazorCompileOnBuild>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Hosting" Version="7.0.1" />
    <PackageReference Include="Microsoft.Extensions.Hosting.WindowsServices" Version="7.0.1" />
  </ItemGroup>
  <ItemGroup>
      <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>
  <ItemGroup>
    <Folder Include="Views\Home\" />
    <Folder Include="Views\Shared\" />
  </ItemGroup>
</Project>

3.程序.cs

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

namespace WorkerService1
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var builder = WebApplication.CreateBuilder(args);

            builder.WebHost.ConfigureKestrel(serverOptions =>
            {
                serverOptions.ListenAnyIP(5000); // http
            });

            builder.Services.AddControllersWithViews();
            builder.Services.AddWindowsService();
            builder.Services.AddHostedService<Worker>();

            var app = builder.Build();

            // Configure the HTTP request pipeline.
            if (!app.Environment.IsDevelopment())
            {
                app.UseExceptionHandler("/Home/Error");
                // The default HSTS value is 30 days. You may want to change this for production scenarios, see https://aka.ms/aspnetcore-hsts.
                app.UseHsts();
            }

            app.UseHttpsRedirection();
            app.UseStaticFiles();

            app.UseRouting();

            app.UseAuthorization();

            app.MapControllerRoute(
               name: "default",
               pattern: "{controller=Home}/{action=Index}/{id?}");

            app.Run();

            //IHost host = Host.CreateDefaultBuilder(args)
            //    .ConfigureServices(services =>
            //    {
            //        services.AddHostedService<Worker>();

            //    })
            //    .Build();
            //host.Run();
        }
    }
}

===更新===

4.将项目SDK更改为Web，然后我们会发现项目图标将更改，我们需要重新加载项目。

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>net7.0</TargetFramework>
    <Nullable>enable</Nullable>
    <ImplicitUsings>enable</ImplicitUsings>
    <UserSecretsId>dotnet-WorkerService1-d5189c80-2268-4d3c-9c71-bf06594ee612</UserSecretsId>
    <RazorCompileOnPublish>true</RazorCompileOnPublish>
    <RazorCompileOnBuild>true</RazorCompileOnBuild>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Hosting" Version="7.0.1" />
    <PackageReference Include="Microsoft.Extensions.Hosting.WindowsServices" Version="7.0.1" />
  </ItemGroup>
  <ItemGroup>
      <FrameworkReference Include="Microsoft.AspNetCore.App" />
  </ItemGroup>
  <ItemGroup>
    <Folder Include="wwwroot\" />
    <Folder Include="Views\Home\" />
    <Folder Include="Views\Shared\" />
  </ItemGroup>
</Project>

4.然后我们需要将应用程序发布为单个文件。

5.创建 Windows 服务并手动启动它

6.检查端口 5000。
