How do I use Structuremap 3 with objects that aren't friendly to constructor injection?

Question

I'm moving from StructureMap 2.x to 3.x. One major change is that using ObjectFactory results in the following warning:

'StructureMap.ObjectFactory' is obsolete: 'ObjectFactory will be removed in a future 4.0 release of StructureMap. Favor the usage of the Container class for future work'

So in most cases, the resolution is fairly easy: pass through IContainer as a constructor. Unfortunately this is not feasible for ASMX web serivces or attributes, both of which require a default constructor. That means I'm probably stuck with the Service Locator Pattern, property injection, or writing my own ObjectFactory implementation.

What's the preferred way to deal with this unfortunate problem?

Edit: It's worth mentioning that my container does an Assembly scan.

Per Jeremy Miller, himself:

Assembly scanning isn’t cheap and you (almost?) always wanna cache the results. So, yeah, in that case you’re going to have to write your own ObjectFactory. Someday all that bad old MS tech will go away.

So in this case, this implementation is what should be done.
