Question

All my tables have an integer column as an Id – Primary Key

Except one

        instance.CustomType<int>();
        instance.GeneratedBy.Custom<global::NHibernate.Id.IdentityGenerator>();
        instance.UnsavedValue("0");

Is there a way to ignore the primary key convention for this one mapping file?

          mapping.Id(a => a.Id, "RoleName").GeneratedBy.Assigned();

Thanks

You can override it. Although it looks like you are try to use a mixture of both Fluent NH Automapping and mapping by code which I’m not sure that it will work in this case. I would override it like this:

AutoMap.AssemblyOf<Role>().Override<Role>(map =>
{
    map.Id(x => x.Id, "RoleName")
        .CustomType<int>()
        .GeneratedBy.Identity()
        .UnsavedValue("0");
});

I took the basic idea from: https://github.com/jagregory/fluent-nhibernate/wiki/Auto-mapping
