The dotSpatial utilities are not yet incorporated in the FluidEarth SDD (see http://dotspatial.codeplex.com, and also http://code.google.com/p/nettopologysuite for the topology aspects of geometrical entities).
Remark (Jesper): if these kind of utilities are used in the SDK, they should be added in such a way that they can easily be replaced. Adrian explains that it is indeed the way it is set up, also to avoid that wrappers only run on Windows/.Net and not on Linux/Mono if some of the utilities are not available on the latter.
