This article from our series of articles about WPF development and MVVM pattern tells about some tricky things when creating WPF MVVM Application. First of all it is “close the window” (you are not allowed to access the window object in WPF MVVM). Second is how to link View and ViewModel. And last is how to make OnPropertyChanged method without string with name of property and add IntelliSense.
