Migrating Transaction Library
TransactionLibrary and transactions has undergone the smallest change of the API. It continues being powered by SQL server and requires the access and usage of Entities via NHibernate.

This has changed namespace and assembly and can now be accessed via:
Ucommerce.Api.ITransactionLibrary transactionLibrary = Ucommerce.Infrastructure.ObjectFactory.Instance.Resolve<Ucommerce.Api.ITransactionLibrary>();
