You can often resolve circular dependency issues with Dependency Injection (DI) using an Abstract Factory. See here for an example.

However, although you may be able to solve the problem with DI, it would be better to redesign the API to make the circular dependency go away.

You can often break a circular dependency by changing one of the ends from a query-based API to an event-based API.
