I need some help on how to use the different RuleContextModes values

[GreatBarrier86]

I could use some explanation for how the different RuleContextModes values work.

CheckRules seems to mean someone manually called CheckRules/CheckRules(MyProperty)
CheckObjectRules seems to mean someone manually called CheckObjectRules()

I'm unclear on how PropertyChanged differs from AsAffectedProperty? Does PropertyChanged mean the rule fired because that property associated with the rule had changed and AsAffectedProperty means that the rule ran since that property was dependent on the one that did change?

I don't know the answer for sure and definite, but it certainly seems to me that you are right in what you have surmised. I would read it exactly as you have, as your understanding of it seems to be reinforced by the comments. AsAffectedProperty will be to do with rules where an update to one property - the primary property to which the rule is attached - are marked as also affecting one or more other properties.

@rockfordlhotka, do @TheCakeMonster and I basically have this correct? If you have a moment, I'd appreciate any other feedback you might have on it.

The expert is @jonnybee, though his career has moved him off CSLA.

I think you've summarized it as I understand it. Have you looked at the rules sample apps? Jonny wrote them to illustrate how this works.
