Hi,
When I updated my project Im getting these errors. 
"no suitable method found to override " for all function.
How can i fix the problem ?

Hello Murat,

The custom map provider architecture is not backwards compatible with previous versions. For more information about changes of the Q1 2011, please, take a look to the release history:
http://www.telerik.com/products/silverlight/whats-new/release-history/q1-2011-version-2011-1-0315.aspx

Please see the following topic of RadMap: "Custom map provider architecture is not backwards compatible with previous versions".

Also you can look at the "How to implement custom map provider" documentation topic:
http://www.telerik.com/help/silverlight/radmap-howto-custom-provider.html

I have attached a sample solution with your custom provider. I have updated it according to new architecture.

Regards,
Andrey Murzov
