Andrei Alecu commented on NH-2328:
----------------------------------

Ok, since I was pressed on time, I ended up with the following workaround which works:

    public static class GetTypeFullNameExtension
    {
        public static string GetTypeFullName(this object what)
        {
            return what.GetType().FullName;
        }
    }

    public class TypeIsGenerator : BaseHqlGeneratorForMethod
    {
        public TypeIsGenerator()
        {
            this.SupportedMethods = new[] { ReflectionHelper.GetMethodDefinition<object>(x => x.GetTypeFullName()) };
        }

        public override HqlTreeNode BuildHql(
            MethodInfo method, 
            Expression targetObject, 
            ReadOnlyCollection<Expression> arguments, 
            HqlTreeBuilder treeBuilder, 
            IHqlExpressionVisitor visitor)
        {
            return treeBuilder.Dot(visitor.Visit(arguments[0]).AsExpression(), treeBuilder.Class());
        }
    }

After merging the generator in, I can now run this query:

				var boxes =
					(from t in s.Query<ToyBox>()
					 where t.Shape.GetTypeFullName() == typeof(Square).FullName
					 select t).ToList();

Which is sufficient for us for now.

> I excluded the lib folder from the zip file since upload says not to include dlls. I am using NH 3 Alpha 2 with all supporting dlls. First time posting bug..sorry in advance if I am doing it wrong.
