Question

I have a Visual Studio 2010 MVC 3 web solution containing a number of projects. One of these projects is my site, another handles data access.

I am using NHibernate to access my database and I have put all my mapping files, nhibernate.config and NH DLLs inside the data access project.

I have enough of an idea how to use NHibernate but I’ve only ever used it in small, single test projects – never a solution with multiple projects

I want to reference the nhibernate.config in my site’s web.config – can I do that?
If not what should I do? Put all the the NH DLLs in my site’s bin folder and stick the NH config straight into my DLL?

Totally lost – all help appreciated!

Answer 1

I would put nhibernate.config in your web project and your data access layer would create a session factory like this:

private ISessionFactory CreateSessionFactory()
{
    Configuration cfg;
    cfg = new Configuration().Configure(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "nhibernate.config"));
    return (cfg.BuildSessionFactory());
}

Always searching nhibernate.config in a base directory, so you can reference your DAL in other projects.
