Answer 1

Maybe it's too late to answer but i had the same problem.

I added scope timeout (5 minutes). I let an example.

Dim varIntervalo As New TimeSpan(0, 5, 0)
Using varTransaccion As New TransactionScope(TransactionScopeOption.Required, varIntervalo)
    For vari As Integer = 2 To varMatrizDatos.GetUpperBound(0)
        Dim varWhateverAs New TABLE
        varWhatever.ID_TABLE = something
        varWhatever.DESC_TABLE = something else
        varWhatever.DATE_TABLE = CDate(Now.Date)

        varEntidades.AddToTABLESet(varWhatever)
        varEntidades.SaveChanges()
    Next
    varTransaccion.Complete()
End Using

Maybe this code could be improve.
