The central communication between a MDriven application and its Remote Persistence Layer is handled by PersistenceProvider. During the many iterations of development this has been implemented with RPC, WCF(until recently the current) and the new implementation is WebApi.

To use WebAPI communication instead of WCF you use the new PersistenceMapperWEBAPIClient (MDriven.Net.Http.dll) instead of PersistenceMapperWCFClient. And on the server you subclass the public abstract class MDrivenPersistenceController<T> : ApiController (MDriven.Persistence.WebApi.dll).
