Hello Sudhanshu Tripathi,
We changed the name of Telerik.OpenAccess.Query
We suggest you use our new Visual Designer for OpenAccess ORM. It is available under the "Add New Item" dialog and is called OpenAccessDomainModel. It is quite intuitive for use and we suggest you use it. Also a data context similar to those of L2S and EF is created by the designer, and you can use that instead of using a scope.
