What do you think about http://microsoftnlayerapp.codeplex.com/ ? I am interesting in data access implementation (UnitOfWork, repositories, transactions). Is it the "best" example of implementing this issue on microsoft technologies ? If you have some interesting samples or posts describing implementation UnitOfWork + Repository with transaction management please share them.
EDIT: I just want to know some thoughtes of expert about this implementation or some usefull links which can help me to solve my problem.
You can see this sample : http://nhibernateasp.codeplex.com/ but is based on NHibernate that is a good solution for data access layer.
