Nhibernate what is session

When using background initialization, if an error occurs on the background thread it will not be handled and the behaviour will fall back to lazy initialization upon first use of the session factory. If you know there is a chance of this happening then you can choose to either ignore the exception by using the supplied no-op action BackgroundInitialization.

IgnoreException as the first argument to WithBackgroundInitialization Sometimes you want to know when a session factory is initialized so that you can take some action when it occurs, such as logging, tracing or integration with third party libraries. NHibernate provides the notion of a "current session" for a given session factory so that the same session can be used by various parts of your application's request processing pipeline.

When this has been configured via the NHibernate Configuration object and you're using either ILazySession or ILazySessions , you can specify a callback for letting you know when a new session has been opened by calling WithSessionOpenedCallback Note: Don't use ThreadStaticSessionContext in multiple session factory scenarios, as it isn't compatible. When using NHibernate current session context, it's important to unbind and dispose the current session when the logical scope completes as defined by the lifecycle of "current".

You would typically unbind and dispose the session at the end of a business transaction. In a web application, this is commonly implemented using the session-per-request pattern. In a multiple session factories scenario it can be useful to create a separate context class for each session factory being used so that you can refer to it in a strongly typed way.

You can easily define your own named contexts by inheriting from either SessionFactoryContext or SessionContext , as shown in the following examples:. Skip to content. Sessions Public. Star 4.

Even if the database driver supports TransactionScope , it must be used with a transport that also supports TransactionScope i. If a transaction is elevated to a distributed transaction and the transport or environment doesn't support it, the following exception will be thrown:.
