Queryable vs Enumerable

Pill Category

Frameworks (Entity Framework)

Description

Known fact: DbSet is IQueriable

• In Entity Framework, the DBSet class implements IQueriable interface. So, all the Linq queries that we write are applied on an IQueriable object.

Cast IQueriable to IEnumerable

• But, what happens if we cast this IQueriable to IEnumerable and then apply the same Linq query?

Question

• How is the execution affected if we cast the IQueryable to IEnumerable before applying that Linq query?
