The WPF report viewer has been released in Q1 SP1, so it is not available in older versions. There aren't any other possible components in our product that can cause compatibility issues with the RadControls for WPF suite.
As for the master-detail inquiry - this is irrelevant for the reporting product. You bind both master and detail report like you would normally do and hook the connection between both through the report parameters. For more info see Creating Master-Detail Reports Using SubReports
All the best,
