Thank you for contacting us.
Indeed it is likely that the error you are experiencing could occur due to inconsistent versions of the Telerik Data Access assemblies in the bin folder
of your projects. We would recommend deleting the bin folders
of the projects in your solution which have references to Telerik Data Access assemblies and then rebuilding
the solution. This should resolve the situation.
I hope this helps. Should you have further questions, feel free to post at our forums again.
