Ok. Your suggestion is: One instance of Conversation per Form but not a ConversationScope instance per Form. I should create one instance of ConversationalScope when I need to make some operation on the database. This operation could be the simple save of one entity or a complex business operations that involve more methods in different classes. This is the same rule as the Transaction, isn't it?
So I can replace the TransactionScope with ConversationalScope? Thanks again. On 14 Ott, 00:14, José F.
