How do I manage disposing an object when I use IoC? My case it is Ninject.

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

But sometimes I need to keep the context longer or between function calls. So I want to control this behavior through IoC scope.

// 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>()) 
{
}

Sample scopes

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