Josè thanks for the answers, you point me in the right direction (I
hope).
May be I found a solution:
If I create a ConversationalScope object in the form load (and dispose
it when the form closes) everything seems to be ok.
Of course If I need I can create a new ConversationalScope object for
transaction pourpose. Following the example.
private void Form1_Load(object sender, EventArgs e)
{
conversational = new ConversationalScope(conversation);
dataGridView1.DataSource = Fiber.FindAll();
}
