SpecFlow Re-usable step definitions

Is there a way to have SpecFlow reuse Step Definitions?

In other tools I have used a GivenWhenThen base class that contains methods such as

WhenAnOrderIsCreated -- this inits a protected order member to be used by inheriting classes.

Just cant seem to get this working with SpecFlow (doesnt seem to like inheritance)

Is there a way to share steps across features?

Many thanks
