This article explains the manual changes required when upgrading to Telerik Reporting Q1 2014 SP1 (18.104.22.1687).
The ITileProvider properties TileImageFormat and ImagerySet are no longer supported. When using BingMapsTileProvider, you can set its ImagerySet property directly. For any other tile provider please use the GenericTileProvider's UrlTemplate property.
The MapQuestTileProvider is now obsolete and it is being substituted by the GenericTileProvider. For backwards compatibility the reports designed using MapQuestTileProvider will still run, but a warning will be generated during compilation. To avoid this warning, consider using the GenericTileProvider class, which by default uses the MapQuest tile server settings. For more information see Tile Providers documentation article.
The TileImageFormat property is now obsolete. When using BingMapsTileProvider, the tiles image format will be automatically set by its Imagery Metadata. For any other case you should be able to define it using the UrlTemplate property. For more information see Tile Providers documentation article.
The viewer is build with Telerik UI Controls for WPF 2014.1.331.40. If you are using a newer version consider adding binding redirects. For more information see: How to: Add report viewer to a WPF .NET Framework project
The viewer is build with Telerik UI Controls for Silverlight 2014.1.331.1050.
