How to create a simple JOIN LINQ query to fetch data from 2 entities?

The below LINQ query will retrieve the Employee details by joining (inner join) Department table to fetch the DepartmentName using the DeptID in Employee table.
     
  EmployeeInfoDataContext dbEmp = new EmployeeInfoDataContext();
        var query = from emp in dbEmp.Employees
                    join dept in dbEmp.Departments
                        on emp.DeptID equals dept.DeptID
                    select new
                    {
                        EmpID = emp.EmpID,
                        EmpName = emp.EmpName,
                        Age = emp.Age,
                        Address = emp.Address,
                        DeptName = dept.DepartmentName
                    };
