Asp.Net Core RC2中IHostingEnvironment的构造函数依赖项

Question

如何在ServiceUtility类中为IHostingEnvironment创建构造函数依赖项。如何在Startup ConfigureServices方法中绑定IHostEnvironment的依赖项。

自定义类

public class ServiceUtility
    {
        private IHostingEnvironment _environment;
        public ServiceUtility(IHostingEnvironment environment)
        {
            _environment = environment;
        }
    }
