I was gathering the assembly from the model itself. Below is the code
I was using to call the method I posted before.
var config = NHibernateSession
.Init(new HttpContextSessionStorage(), new Assembly[]
{
typeof(ProductMap).Assembly
});
However I had a new look over the Fluent NHibernate wiki pages and
changed my code to setup the NHibernate configuration using
FluentConfiguration. Using that everything seems to be working now.
I'm not sure why the extension method AddMappingsFromAssembly wasn't
working for a plain old configuration but it definetely wasn't picking
up on my mapping classes because I added a break point in the mapping
class as suggested which never hit.
All is ok now though, thanks for your help.
