this is my code.

the idea being to set the data context of the MainWindow.
However, I am given 2 main windows, one blank, one with all the stuff in the view model.
(I was attempting to replicate the example here
for my own objects.)

protected override void OnStartup(StartupEventArgs e)
MainWindow window = new MainWindow();
var viewModel = new AllConversationsViewModel();
MainWindow.DataContext = viewModel;

any clues?
