The `Where` method returns a collection. In this case, the filter select a single entity, so the `Single` method is called to convert the collection into a single `Instructor` entity. The `Instructor` entity provides access to the `Course` navigation property.
The `Where` method returns a collection. In this case, the filter selects a single entity, so the `Single` method is called to convert the collection into a single `Instructor` entity. The `Instructor` entity provides access to the `Course` navigation property.

The <xref:System.Linq.Enumerable.Single%2A> method is used on a collection when the collection has only one item. The `Single` method throws an exception if the collection is empty or if there's more than one item. An alternative is <xref:System.Linq.Enumerable.SingleOrDefault%2A>, which returns a default value if the collection is empty. For this query, `null` in the default returned.
