I have a windows project that is comprised of multiple windows forms. In this project I have 3 support classes
BrObjects (Business objects)
BrValidation (various validation routines and value checking calls)
DataManager (handles querys, getting datasets, executing data commands etc)

Each windows form in the project needs and utilizes these 3 classes.

So here is my theory question: I currently create an instance of each of the 3 classes in each form (works fine). Is that the best way to do it? Is there a better way? Is it true that when the form is close() that Garbage Collection will eventually remove the memory used by the instance of these 3 classes?



Thanks
