问题 My Saga message handler (configured as ISagaStartedBy) requests a timeout message for every message received. Debugging through a few messages at a time, I've found the time the first time the handler is fired, the saga ID sent to the timeout manager is different to the one a) persisted in the database and b) the saga ID sent in subsequent messages. The subsequent messages all send the Saga ID from the database. Here's the handler: public void Handle(PaymentRequested message) { int

问题 I was reading this article and found it quite interesting (thanks @Aaronaught). Was what came closest to solve my problem. The only detail is that in my case I would use the NHibernate interceptor, but an exception is thrown An unhandled exception of type 'System.StackOverflowException' occurred in System.Core.dll Code Session factory: public class SessionFactoryBuilder : IProvider { private ISessionFactory _sessionFactory; private readonly Configuration _configuration; public

问题 I have a class structure which is akin to a PurchaseOrder (parent) and PurchaseOrderLine (child) pattern, where the order lines will only be saved to the DB by saving the parent PurchaseOrder and will only ever be accessed via the parent too. The DB has PurchaseOrderLine.PurchaseOrder set to not permit null values. It seems from searching through the web that it is not possible to have a uni-directional association from PurchaseOrder via an IList property without having to have a property on
