Bind a list of the same type viewModels to a tabcontrol in Caliburn.Micro

I'm having trouble binding a list of ViewModels as items to a tab control.

//ShellViewModel.cs
private BindableCollection<RecentUnitViewModel> RecentUnitModels { get; set; }

<!-- ShellView.xaml -->
<GroupBox FontSize="16" Margin="10" FontWeight="DemiBold" Grid.Row="3">
    <GroupBox.Header>Last Seen</GroupBox.Header>
    <TabControl ItemsSource="{Binding RecentUnitModels}" >
    </TabControl>
</GroupBox>

Unexpected result: Displays the type "RecentUnitViewModel" instead of the View.

The Caliburn binding for a TabControl is easiest if you have a Conductor that you bind by convention (set the DataContext to the Conductor instance and name the TabControl "Items".) The issue here is that a TabControl instantiates a single content presenter that is shared by all tabs, but you need to somehow tell Caliburn.Micro to find the View for the ViewModel when it changes the content. I found that this works nicely:

        <TabControl.ContentTemplate>
            <DataTemplate>
                <ContentControl cal:View.Model="{Binding}"/>
            </DataTemplate>
        </TabControl.ContentTemplate>

I've made the assumption here that the ViewModels you're binding are true ViewModels (not UserControls) and that you have separate Views (UserControls) that Caliburn.Micro is binding for you.

You property needs to be public...
