None of the constructors found with 'Autofac.Core.Activators.Reflection.DefaultConstructorFinder'

这个错误是在nopcommerce中添加了一个service以后，但没有在DependencyRegistrar注册造成的。

None of the constructors found with ‘Autofac.Core.Activators.Reflection.DefaultConstructorFinder’ on type ‘*’ can be invoked with the available services and parameters:
Cannot resolve parameter ‘’ of constructor ‘Void .ctor()’.

• DependencyRegistrar注册

   builder.RegisterType<***Service>().As.InstancePerLifetimeScope();

• 构造函数注入 必须注入接口，非实现

• 接口必须有实现
