The type of the elements of the IQueryable<'T> that is returned.


The Expression property of the returned IQueryable<'T> object is equal to expression.

The CreateQuery<'TElement> method is used to create new IQueryable<'T> objects, given an expression tree. The query that is represented by the returned object is associated with a specific LINQ provider.

Most of the Queryable standard query operator methods that return enumerable results call this method. They pass it a MethodCallExpression that represents a LINQ query.
