entity framework - ObjectContext.Refresh()?

Question

How to update ALL the dirty entities from the data store, and reset their changed values to the original store value?

The method ObjectContext.Refresh requires as a parameter the entities to be refreshed.

Answer 1

The following usually works:

Context.Refresh(RefreshMode.StoreWins, _
    Context.ObjectStateManager.GetObjectStateEntries())

It sometimes causes problems with EntityRelations. look at my comment for further details.
