As you may have gathered from my last post, I’ve been playing around with Click Once a bit lately.Dealing with the unwrapped exceptions is easier and better in terms of code readability.Sometimes aggregate exception contains more than one exception.Thanks to captured context it will be done on UI thread.If it were not for capturing context we would end up updating textbox object from non-UI thread, that would lead to an exception.In this case, the first exception is taken from inner exception list during unwrapping.
