Procedural Flow Control – Example private void DoSomeTransactionalWork(IDbSesion) { … } IDbSession session = new DbSession(); session.BeginTransaction(); try { DoSomeTransactionalWork(session); session.CommitTransaction(); } catch (Exception) { session.RollbackTransaction(); throw; } Step by step execution
