Multi-Tenant w / NHibernate + Castle Windsor (single application, multiple DB)

Creating a multi-tenant asp.net mvc 3 application with one application instance / several databases for each tenant. A separate “master” database will also be created, in which data specific to the tenant will be placed (included functions, information about connecting to a db connection, etc.). New to NHibernate and IOC (Castle Windsor) and used this tutorial to get a basic CRUD setup.

The following is what I use (from the above tutorial) to use NHibernate:

 public class PersistenceFacility : AbstractFacility
    {
        protected override void Init()
        {
            var config = BuildDatabaseConfiguration();

            Kernel.Register(
                Component.For<ISessionFactory>()
                    .UsingFactoryMethod(config.BuildSessionFactory),
                Component.For<ISession>()
                    .UsingFactoryMethod(k => k.Resolve<ISessionFactory>().OpenSession())
                    .LifeStyle.PerWebRequest);
        }

        private Configuration BuildDatabaseConfiguration()
        {
            return Fluently.Configure()
                .Database(SetupDatabase)
                .Mappings(m =>
                {
                    m.FluentMappings.AddFromAssemblyOf<SectionMap>()
                                    .Conventions.AddFromAssemblyOf<TableNameConvention>();
                })
                .ExposeConfiguration(ConfigurePersistence)
                .BuildConfiguration();
        }

        protected virtual AutoPersistenceModel CreateMappingModel()
        {
            var m = AutoMap.Assembly(typeof(EntityBase).Assembly)
                .Where(IsDomainEntity)
                .OverrideAll(ShouldIgnoreProperty)
                .IgnoreBase<EntityBase>();

            return m;
        }

        protected virtual IPersistenceConfigurer SetupDatabase()
        {
            return MsSqlConfiguration.MsSql2008
                .DefaultSchema("dbo") 
                .UseOuterJoin()
                .ProxyFactoryFactory(typeof(ProxyFactoryFactory))
                .ConnectionString(x => x.FromConnectionStringWithKey("MasterDB"))
                .ShowSql();
        }

        protected virtual void ConfigurePersistence(Configuration config)
        {
            SchemaMetadataUpdater.QuoteTableAndColumns(config);
        }

        protected virtual bool IsDomainEntity(Type t)
        {
            return typeof(EntityBase).IsAssignableFrom(t);
        }

        private void ShouldIgnoreProperty(IPropertyIgnorer property)
        {
            property.IgnoreProperties(p => p.MemberInfo.HasAttribute<DoNotMapAttribute>());
        }
    }
