Hi&nbsp;Helmut,&nbsp;  
&nbsp;&nbsp;  
&nbsp;For&nbsp;simple&nbsp;use&nbsp;it,&nbsp;you&nbsp;can&nbsp;directly&nbsp;use&nbsp;that&nbsp;like&nbsp;this:&nbsp;  
&nbsp;&nbsp;  
&nbsp;`  if (!Page.IsPostBack)            {                Map1.MapBackground.BackgroundBrush = new GeoSolidBrush(GeoColor.FromHtml("#E5E3DF"));                Map1.CurrentExtent = new RectangleShape(-2000000, 2000000, 2000000, -2000000);                Map1.MapUnit = GeographyUnit.Meter;                BingMapsOverlay worldMapKitOverlay = new BingMapsOverlay();                Map1.CustomOverlays.Add(worldMapKitOverlay);            }`&nbsp;  
&nbsp;&nbsp;  
&nbsp;But&nbsp;if&nbsp;you&nbsp;need&nbsp;use&nbsp;that&nbsp;in&nbsp;your&nbsp;product&nbsp;for&nbsp;get&nbsp;more&nbsp;tiles,&nbsp;the&nbsp;Credentials&nbsp;is&nbsp;used&nbsp;for&nbsp;assign&nbsp;the&nbsp;key&nbsp;which&nbsp;you&nbsp;got&nbsp;from&nbsp;BingMap.&nbsp;  
&nbsp;&nbsp;  
&nbsp;Regards,&nbsp;
