Hey Scott,
neat book, learning a lot from it and your other arch books. At the moment I'm seeking a bit of clarification.

In the book chapters itself (not the case study which there are errors as _uow is not hooked into) you have an Iunitofwork iface which gets implemented by nhibernate which essentially delgates down to session.save/session.delete etc.

However in the base repository class you call, registernew etc. while always passing in null for an implementation of Iunitofworkrepostory, why is this? It is just another layer of abstraction in case a different ORM does it differently?

hi Mr David,

Thanks for buying the book. Yes the implementation is to support a non ORM scenario, if you read the Unit of Work section in the book at page 198 it describes the roles of IUnitOfWorkRepostory and later in the chapter why is isn't needed for ORMs. I tend to now favor having the transactions hook up to the start and end of a request (session per request http://code.google.com/p/walkme/sour...equest+.cs?r=8) or before and after action on a controller (like http://ayende.com/blog/4809/refactor...t-transactions) so that I don't have to keep explicitly calling commit.

let me know if you need any more details.

Cheers
Scott
