How do I set the default transaction isolation level in Fluent NHibernate?

Question

I would like to set the default transaction level to ReadCommitted in my Fluent NHibernate configuration. If I were using XML mapping files, I could add a key to my config file:

<add key="hibernate.connection.isolation" value="ReadCommitted" />

but I can't figure out how to accomplish this with Fluent configuration.

Answer 1

Fluent NHibernate doesn't do anything with the transaction isolation, so the default will be whatever NHibernate defaults to. I don't know off the top of my head what that is.

We don't have an explicit method to set the isolation, but as it's just a configuration value you can use the Raw method to set the property.

MsSqlConfiguration.MsSql2008.Raw("connection.isolation", "isolation_level");
