This is actually supported in 0.57 ( and higher) versions.  We are in the process of documenting it now and will probably complete the documentation before the end of the week.

 But for now, the basic idea is to subclass the EFContextProvider and override either or both of the following methods
1) BeforeSaveEntity
2) BeforeSaveEntities

A simple scaffolding is shown below. 

 public class NorthwindContextProvider: EFContextProvider<NorthwindIBContext_CF>  {  

    public override bool BeforeSaveEntity(EntityInfo entityInfo) {
      return true;
    }

    public override Dictionary<Type, List<EntityInfo>> BeforeSaveEntities(Dictionary<Type, List<EntityInfo>> saveMap) {
      return saveMap;
    }
     
  }

  public class NorthwindIBModelController : ApiController {

    NorthwindContextProvider ContextProvider = new NorthwindContextProvider();

I would like to force some restrictions during data modifications. 
Instead of simple return _contextProvider.SaveChanges(saveBundle); I need more control during/before save.
How can I execute custom logic during save?
