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.
A:
If you want to reset ALL the changes, you could set the ObjectContext to null and re-instantiate it.
I believe this will achieve what you want.

I guess you work with ASP.NET, so it's easy for you to say it, I use a long life-cycle context instance.

A:
The following usually works:
Context.Refresh(RefreshMode.StoreWins, _
Context.ObjectStateManager.GetObjectStateEntries())
It sometimes causes problems with EntityRelations. look at my comment for further details.

This just saved me many lines of code walking the object graph myself.

Sometimes you'd like to update even the unchanged items, cuz you want to refresh them against the changes made in database by other clients.
