How do you map an enum as an int value with fluent NHibernate?

Question

Question says it all really, the default is for it to map as a string but I need it to map as an int.

I\'m currently using Persistenc

Don't forget about nullable enums (like ExampleEnum? ExampleProperty)! They need to be checked separately. This is how it's done with the new FNH style configuration:

public class EnumConvention : IUserTypeConvention
{
    public void Accept(IAcceptanceCriteria criteria)
    {
        criteria.Expect(x => x.Property.PropertyType.IsEnum ||
            (x.Property.PropertyType.IsGenericType && 
             x.Property.PropertyType.GetGenericTypeDefinition() == typeof(Nullable<>) &&
             x.Property.PropertyType.GetGenericArguments()[0].IsEnum)
            );
    }

    public void Apply(IPropertyInstance target)
    {
        target.CustomType(target.Property.PropertyType);
    }
}
