Issue with nHibernate upgrade to 3.3

I just upgraded my .net windows apps from nHibernate 1.2 to 3.3 but having an issue now. During runtime, it throws the following error:

A first chance exception of type 'NHibernate.InvalidProxyTypeException' occurred in NHibernate.dll NHibernate.InvalidProxyTypeException: The following types may not be used as proxies: CallType : method Equals should be 'public/protected virtual' or 'protected internal virtual' .....

Here's the class:

public class CallType : DomainObject<int>
{
        public virtual String Description
        {
            get;
            protected set;
        }
        public virtual String Name
        {
            get;
            protected set;
        }

        public CallType()
        {}

        public override int GetHashCode()
        {
            return string.Format("{0}|{1}", Description, Name).GetHashCode();
        }
}

Did I miss anything? All members are public virtual. Lazy loading is required in this application

You are inheriting from DomainObject. I suspect this class has a method Equals in it, and it is probably not set to virtual.

The constructor CallType does not need to be virtual as some people mention.
