Hello Kevin,

Thank you for contacting us.

Generally this error occurs when the Telerik.OpenAccess assembly cannot be found or the version of the found assembly is different than the one specified in the reference. With this in mind we suggest you verify that the assembly is available and has the same version as the one in its reference. Furthermore you can check whether there is an assembly redirect in the .config file of your application which specifies a different version than the one of the available assembly.

Should the issue continue to persist, could you provide us with some additional details:
  1. Does the error occur in your development environment or when the application is deployed?
  2. Have you upgraded the version of Telerik Data Access before the error started occurring?
  3. Are you using a Domain Model (.rlinq file) or a Fluent Model?

This should allow us to gain better understanding of your situation.

We are looking forward to your feedback.

Kristian Nikolov
