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

Answer 1

You could make the constructor on your MyBusinessObjectClass class internal, and move it and the factory into their own assembly. Now only the factory should be able to construct an instance of the class.
