The CreateQuery method is used to create new IQueryable objects, given an expression tree. The query that is represented by the returned object is associated with a specific LINQ provider.
Several of the standard query operator methods defined in Queryable, such as OfType(Of TResult) and Cast(Of TResult), call this method. They pass it a MethodCallExpression that represents a LINQ query.
