Often clients need to change the colors of the Bing / OpenStreet Maps.
Reasearch for a possible solution and add it in XAML SDK GitHub if possible.
Yes, I need this! A possible technique for doing this can be found here: http://rbrundritt.wordpress.com/2009/11/27/bing-maps-custom-tile-skinner/
I'd like to be able to display the map in gray scale to emphasise my coloured data layer. I currently change the opacity of the map but gray scale would be much nicer.
