Hi,
Currently there is no public property to hide the logo - we will consider adding one in a future release.
It is possible to hide the logo - but note that you still need to attribute Esri as follows (Deploy an app—ArcGIS Runtime SDK for .NET | ArcGIS for Developers):
- ArcGIS Runtime SDK for .NET—About and Credit screens must include the following text: Mapping API provided by Esri ArcGIS Runtime SDK for .NET.
- Map data—All map data used in an application must be attributed in the About and Credit screens using the Copyright Text section of the REST endpoint or endpoints being used. For example, ESRI_Imagery_World_2D service must useCopyright:© 2009 ESRI, i-cubed, GeoEye.
- Esri logo—If your application uses data served by Esri through ArcGIS Online, display a logo on the map pursuant to the logo guidelines below. Examples of such data can be found on the ArcGIS Online maps page.
To hide the logo you will need to customize the MapView's template - here is an example with the Logo image commented out:
<Window.Resources>
<Style x:Key="NoLogoStyle" TargetType="{x:Type esri:ViewBase}">
<Setter Property="IsTabStop" Value="true" />
<Setter Property="Background" Value="Transparent" />
<Setter Property="IsManipulationEnabled" Value="True" />
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="esri:ViewBase">
<Border Background="{TemplateBinding Background}"
BorderBrush="{TemplateBinding BorderBrush}"
BorderThickness="{TemplateBinding BorderThickness}">
<Grid x:Name="MapSurface" Width="Auto" Height="Auto" >
<Rectangle x:Name="ZoomBox" Fill="#55FFFFFF" Stroke="Red" StrokeThickness="2" Visibility="Collapsed" />
<!--<Image Source="..."
x:Name="EsriLogo"
HorizontalAlignment="Left"
VerticalAlignment="Bottom"
Stretch="Fill"
Margin="10"
IsHitTestVisible="False"
Width="56" Height="32" />-->
<Border x:Name="Overlay" />
</Grid>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<esri:MapView x:Name="MyMapView" Style="{StaticResource NoLogoStyle}">
<esri:Map>
<esri:ArcGISTiledMapServiceLayer ID="Basemap"
ServiceUri="http://services.arcgisonline.com/ArcGIS/rest/services/World_Topo_Map/MapServer"/>
</esri:Map>
</esri:MapView>
</Grid>
Cheers
