Hi,
I've just tried upgrading our application to NHibernate 2.0.0.Alpha1. The main code works fine, but there is a small bit of legacy web-service code that calls out to a .Net assembly using COM Interop. The host process is dllhost.exe, and the configuration is set through code since there is no .config file.
The error appears to be in Microsoft's XmlSerializer. I can get round the problem by giving IWAM_<machine_name> access to C:\Windows\Temp, but I was wondering if there was a way of configuring NHibernate to avoid the use of temporary files?
Hibernate version: NHibernate-2.0.0.Alpha1
Code between sessionFactory.openSession() and session.close():
Code:
// NHibernate configuration is entered in code rather than using .config files
// because the COM-Interop stuff uses the dllhost.exe.config file in System32.
configuration.Properties.Add(NHibernate.Cfg.Environment.ConnectionProvider, "NHibernate.Connection.DriverConnectionProvider");
configuration.Properties.Add(NHibernate.Cfg.Environment.Dialect, "NHibernate.Dialect.MsSql2005Dialect");
configuration.Properties.Add(NHibernate.Cfg.Environment.ConnectionDriver, "NHibernate.Driver.SqlClientDriver");
configuration.Properties.Add(NHibernate.Cfg.Environment.ConnectionString, m_connectionString);
configuration.AddAssembly(m_nHibernateAssembly);

Any help/insight would be appreciated.
