一，繼續上一篇部落格的擴充套件（Grpc+MagicOnion的學習和例子（一）），我們再服務端加入MagicOnion.Hosting包，如下

把startup的配置註釋調，我們再program新增主機配置，如下

program

using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Runtime.Loader;
using System.Threading.Tasks;
using Grpc.Core;
using MagicOnion.Hosting;
 
using MagicOnion.Server;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

namespace grpcDemo
{
    public class Program
    {
        public static void Main(string[] args)
        {
            CreateHostBuilder(args)
                .UseMagicOnion(
                    
 
///程式集配置，其他都是一樣的
                    new[] { AssemblyLoadContext.Default.LoadFromAssemblyName(new AssemblyName("Service")) },
                    new MagicOnionOptions(isReturnExceptionStackTraceInErrorDetail: true),
                    new ServerPort("localhost", 6000, ServerCredentials.Insecure)
                )
                .Build()
                .Run();
        }

        
 
public static IHostBuilder CreateHostBuilder(string[] args) =>
            Host.CreateDefaultBuilder(args)
                .ConfigureWebHostDefaults(webBuilder =>
                {
                    webBuilder.UseStartup<Startup>();
                });
    }
}

二，執行看結果，除錯成功
