    I have used persistance class and used following LINQ query :

    XPQuery<Students> objStudentQuery = new XPQuery<Students>(XpoDefault.Session);
    XPQuery<ExamDetails> objExamDetailsQuery = new XPQuery<ExamDetails>(XpoDefault.Session);
    var ExamDetails = from exm in objExamDetailsQuery
                              join student in objStudentQuery on exm.StudentId equals student.StudentId
                              select new { student.FirstName, student.LastName, exm.ExamName, exm.Marks, exm.Date };

    but it throws an error saying. "Specified Method is not Supported"

    How can i get data from two table using XPO Persistance Class?
