title: How to handle MessageBox.Show from ViewModel in WPF
body: <p>I am writing a WPF application using the MVVM design pattern. I wanted to know the best possible(read "MVVM Complaint") way of doing this. Also be aware that all the code in my view model doesn't run on the UI thread. Currently I am accessing the Dispatcher in the VM using <code>App.Current.Dispatcher</code> and then calling the <code>MessageBox.Show()</code> on it.</p>
