NullReferenceException on ReliableAdoTransaction.ExecuteWithRetry

[marcelom2s]

When I add the following code:

.ExposeConfiguration(c => c.SetProperty(NHCfg.Environment.TransactionStrategy, typeof(ReliableAdoNetWithDistributedTransactionFactory).AssemblyQualifiedName))

to the Fluently.Configure().

I start having this error below:

[NullReferenceException: Object reference not set to an instance of an object.]
NHibernate.SqlAzure.ReliableAdoTransaction.ExecuteWithRetry(ReliableSqlDbConnection connection, Action action) +41
NHibernate.SqlAzure.ReliableAdoTransaction.Begin(IsolationLevel isolationLevel) +91
NHibernate.SqlAzure.ReliableAdoTransaction.Begin() +8
NHibernate.Impl.SessionImpl.BeginTransaction() +314

I use NHibernate 4.1.2.4000.
