Class OnMethodInvokeBaseAdvice

A method interception advice can be applied to an abstract method of the current assembly. PostSharp then gives the method an implementation that throws NotSupportedException, unless another aspect implements the method. The advice runs when the method is called, and gets the exception only when it proceeds to this implementation; an advice that does not proceed returns normally. The overrides of the method in derived classes are not intercepted. The compiler reports warning LA0254 in this case. To exclude abstract methods from a multicast aspect, set the AttributeTargetMemberAttributes property of the aspect, or the TargetMemberAttributes property of its MulticastAttributeUsageAttribute, to NonAbstract. An aspect provider (IAspectProvider) or a pointcut that selects methods must exclude abstract methods itself, because multicast filters do not apply to the targets it selects.
