Hi, I wonder if that's a bug or by design.
Expression returned by Ast.Action.Operator(Operators.NotEquals, Ast.Null(), Ast.Null()) [which I believe is equivalent to null != null] evaluates to True, though False could be expected (overriding MakeRule<T> for this special case does the trick). Having returned LambdaExpression from LanguageContext.ParseSourceCode which has return type of void, produces "System.InvalidProgramException : Common Language Runtime detected an invalid program", changing return type to object solves the problem.
