I was debugging through the Nhibernate code, and I get a first chance exception in the GetSetHelperFactory.Build method: "Unexpected character '`'"

It turns out the code generated in GenerateCode method has an unexpected character in statemennts containing System.Nullables.

The generated code is:

using System;
using NHibernate.Property;

IGetter[] getters;

this.setters = setters;
this.getters = getters;

What version of NHibernate are you using? NH 1.0.x is based on .net 1.1 and does not support Generics. Try NH 1.2.
