Can autofac do partial Resolve?

Question

I seem to need this a lot.

Let's say I have a class with constructor taking several arguments. Some of these can be resolved by registering components. But the rest are instances created during runtime (e.g. fetching an entity from database).

Can Autofac deal with these situations in a nice way? Or is my design sub-optimal?

To clarify, I have classes that have constructors like this:

public MyClass(IService1 service1, IService2 service2, Data1 data1, Data2 data2)
{
//...
}

And I would like to do something like this:

container.Resolve<MyClass>(data1, data2);

You can handle this elegantly by registering a factory method in the Autofac container. You resolve the factory method, and then use it to create instances with your runtime dependencies. You can do this yourself by registering and resolving delegates or custom factory types. However, Autofac has explicit support for delegate factories.

There is not enough information to comment on your design. I'll leave that to you :)
