After one day's work,now i understand the base knowledge about wcf and the structure about the project- CredentialsManager.
The next problem is how to free from aspnetdb written , that means we should write the data to the DB directly.
Abosolutely this step has closed relationship with the class  AspNetDbDataSet.In the line 6029.
int returnValue = this.Adapter.Fill(dataTable);
I doubt that with this line the buffer DB is filled.
So how to find the call-diagram is very important.
