I have followed this guide to integrate a Bing Maps WPF control into my Windows Forms app. But when I start the application and view the map, it appears broken like in this image.
Zooming in and out does not help, the map tiles do not fit together.
Here is the XAML of my WPF user control:
<UserControl x:Class="My.Views.BingMapsUControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

xmlns:maps="clr-namespace:Microsoft.Maps.MapControl.WPF;assembly=Microsoft.Maps.MapControl.WPF"
xmlns:local="clr-namespace:My.Views"
mc:Ignorable="d"
d:DesignHeight="600" d:DesignWidth="800">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="*"></RowDefinition>
<RowDefinition Height="100"></RowDefinition>
</Grid.RowDefinitions>
<maps:Map x:Name="mapControl" Center="48.21,16.37" ZoomLevel="12" Grid.Row="0"
CredentialsProvider="xxx">
</maps:Map>
<ListBox x:Name="listBox" Grid.Row="1"></ListBox>
</Grid>
</UserControl>
