What is the way do such a web app ??? http://gis.moh.gov.sa/publichealthma...healthmap.aspx
I am searching in how to use google maps with ESRI silverlight APIs, i found an article for Mr. Rex Hansen talking about that it is not legal and can be done only using Google Static Maps.
The article URL: http://rexdotnet.blogspot.com/2010/0...lverlight.html
In the same time i found an website using google maps with ESRI Silverlight controls, URL: http://gis.moh.gov.sa/publichealthma...healthmap.aspx
Thank you and waiting for your reply.
