	BusinessRuleBase (IPropertyInfo? primaryProperty)
	Creates an instance of the rule that applies to a specfic property.
void	LoadProperty (object obj, IPropertyInfo propertyInfo, object? newValue)

Additional Inherited Members
Properties inherited from Csla.Rules.BusinessRule
override bool	IsAsync [get, protected set]
	Gets a value indicating whether the rule will run on a background thread.
Properties inherited from Csla.Rules.BusinessRuleBase
bool	CascadeIfDirty [get, protected set]
	If true, rule will only cascade if the primary property is dirty.
bool	PropertiesLocked [get, set]
	Gets or sets a value indicating whether property values should be locked because an async operation is running.
virtual ? IPropertyInfo	PrimaryProperty [get, set]
	Gets or sets the primary property affected by this rule.
List< IPropertyInfo >	AffectedProperties [get]
	Gets a list of properties affected by this rule. Rules for these properties are executed after rules for the primary property.
List< IPropertyInfo >	InputProperties [get]
	Gets a list of secondary property values to be supplied to the rule when it is executed.
bool	IsAsync [get, protected set]
	Gets a value indicating whether the rule will run on a background thread.
bool	ProvideTargetWhenAsync [get, protected set]
	Gets a value indicating that the Target property should be set even for an async rule (note that using Target from a background thread will cause major problems).
string	RuleName [get]
	Gets a unique rule:// URI for the specific instance of the rule within the context of the business object where the rule is used.
RuleUri	RuleUri [get, set]
	Sets or gets the rule:// URI object for this rule.
int	Priority [get, set]
	Gets the rule priority.
RunModes	RunMode [get, set]
	Gets or sets the run in context.
int	DisplayIndex [get, set]
	Gets the rule DisplayIndex in UI.
