// normal explicit dispose
using (var dc = new EFContext) 
{
}

但有时我需要保持上下文更长时间或在函数调用之间.
所以我想通过IoC范围来控制这种行为.

// if i use this way. how do i make sure object is disposed.
var dc = ninject.Get<IContext>() 

// i cannot use this since the scope can change to singleton. right ??
using (var dc = ninject.Get<IContext>()) 
{
}

示例范围

Container.Bind<IContext>().To<EFContext>().InSingletonScope();
// OR
Container.Bind<IContext>().To<EFContext>().InRequestScope();
