Factory pattern in C#: How to ensure an object instance can only be created by a factory class?

Question

Recently I\'ve been thinking about securing some of my code. I\'m curious how one could make sure an object can never be created directly, but only via some method of a fact

I don't understand why you want to separate the "business logic" from the "business object". This sounds like a distortion of object orientation, and you'll end up tying yourself in knots by taking that approach.
