使用配置文件进行依赖性解析

Question

在Asp.Net.Core之前，当我托管我的WEBAPI代码时，我使用Unity和Unity.configuration来定义我的DI。

这样的事情：

<unity xmlns="http://schemas.microsoft.com/practices/2010/unity">
    <container>
        <register type="MyLibrary.Interfaces.IDepartmentManager, MyLibrary"
              mapTo="MyLibrary.DepartmentManager, MyLibrary" />
        <register type="MyLibrary.Interfaces.IFtpFileSender, MyLibrary"
              mapTo="MyLibrary.FtpFileSender, MyLibrary" />
    </container>
</unity>

现在我进入了AspNetCore。

我想出了“编码”是如何工作的。

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;

namespace MyNamespace
{
    public class Startup
    {
        public Startup(IConfiguration configuration)
        {
            Configuration = configuration;
        }

        public IConfiguration Configuration { get; }

        // This method gets called by the runtime. Use this method to add services to the container.
        public void ConfigureServices(IServiceCollection services)
        {
            services.AddMvc();

            /* THE MAGIC !! */
            services.AddTransient<MyLibrary.Interfaces.IDepartmentManager, MyLibrary.DepartmentManager>();
            services.AddTransient<MyLibrary.Interfaces.IFtpFileSender, MyLibrary.FtpFileSender>();
        }

        // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
        public void Configure(IApplicationBuilder app, IHostingEnvironment env)
        {
            if (env.IsDevelopment())
            {
                app.UseDeveloperExceptionPage();
            }

            app.UseMvc();
        }
    }
}

有没有办法使用配置文件（MyDependencies.json）或新的/烘焙依赖引擎？

这是我发现的最接近的事情

但不是直接命中。
