IApplicationBuilder注册到通道中。

具体见启动类Startup.cs：

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    if (env.IsDevelopment())
    {
        app.UseDeveloperExceptionPage();
    }

    app.UseMvc(routes =>
    {
        //配置默认路由
        routes.MapRoute(
            name: "Default",
            template: "{controller}/{action}",
            defaults: new { controller = "Home", action = "Index" }
        );
    });
}

UseDeveloperExceptionPage、UseMvc都是接口IApplicationBuilder的扩展方法。
