title: MvvmLight RaisePropertyChanged("")
body: <p>As per <a href="https://msdn.microsoft.com/en-us/library/system.componentmodel.inotifypropertychanged.propertychanged.aspx" rel="nofollow">MSDN doc on PropertyChanged</a>, if you pass an empty string to the method, all properties are refreshed. Is there such a thing when using MvvmLight RaisePropertyChanged? Passing "" just throw the event with "".</p>
