XAML Inline Syntax versus Property Element Syntax.

For simple xaml elements “inline” syntax where the property is an XML attribute is preferable:

<ListBox>
    <ListBox.ItemTemplate>
        <StaticResource ResourceKey="PathVisualTemplate"/>
    </ListBox.ItemTemplate>
</ListBox>

For more complex elements, “Property Element Syntax” is preferable.

However, Property Element Syntax can also be used in the simple case too:

though this is less pretty than the inline form.
