Telerik Reports are processed, rendered and reside on the server. It is the Telerik Reporting WCF Service
that enables the remote access to the Telerik Reporting Engine and acts as a communication interface between the client programs and the report server. For the reasons above, it is currently not possible to build a Telerik Report on the Silverlight client.
