For the last few weeks, several attempts by people at my company have been made to evaluate the Telerik controls. It appears, the binaries are not compatible with SL3 RTW. As a result we cannot even consider purchasing the controls (and probably won't now as it seems our future releases could be held up by Telerik). Before we look elsewhere, I just want to check it really is the case the 'trial' is not compatible with SL3 RTW - e.g. there maybe a separate download area?
