I've downloaded and run the demo projects for both state validation and interception validation, and neither of them update the tooltip to indicate an error. I've run the projects
through the debugger, and the implementations of the IDataErrorInfo methods aren't ever being called. The only changes I've made to the projects are to *update* existing references to the ValidationAspects library locations on my machine. Is
it possible I'm missing a library, or something else ? Something really simple ?
