I am currently testing an application using EF4.3 containing pre-compiled queries.

                    mqryClientByID = Function(ctx As FGLMainDataEntities, pID As Integer)
                                         Return (ctx.Clients.
                                                 Include("EMails").
                                                 Where("it.ID = " + pID.ToString()
                                                ).Execute(MergeOption.OverwriteChanges).SingleOrDefault())
                                     End Function

This basically get a client's data and his related email addresses.

I just found that if I modify the emails directly in SSMS (simulating another user modifying records), I can see the modification whenever I re-execute my query with:

Dim currentClient = mqryClientByID.Invoke(mobjContext, pID)

But if I delete email addresses related to a client and I reload the client, the row is still shown in the grid.

How can I tell EF to refresh data for real?
