And we can do that by changing from a class to a record type. If I go down now and test my code, even though we've got some red squigglies, we should be fine. And we get a true. Now, one of the other things you may have tried is to change, not to a record, but a struct. And if you tried that, you probably saw something along these lines, saying the operator cannot be applied to operands of type, answer and answer. If you're doing those structs, then you can override that equality. But the simplest way is for us to use the record type that is compared by value. So when we create A and B, our variables down here, and they're two different answer instances, they're compared based on the values of their properties, name, age…
