Entity Framework: Difference between DbSet and IQueryable

In Entity Framework, DbSet and IQueryable are both commonly used for handling database entities, but they serve different purposes and have distinct characteristics.

DbSet:

  • DbSet is a collection of entities that represent a database table or view.
  • It is used for performing CRUD (Create, Read, Update, Delete) operations on database entities.
  • DbSet is a concrete implementation of DbSet<TEntity> class.
  • It allows for easy access to database entities using LINQ queries.

IQueryable:

  • IQueryable is an interface that represents a queryable collection of data.
  • It is used for building dynamic queries against a data source, including databases.
  • IQueryable allows for composing LINQ queries and deferring query execution until needed.
  • It provides greater flexibility in constructing complex queries compared to DbSet.

Overall, DbSet is used for basic CRUD operations and easy entity access, while IQueryable is more powerful for building and executing dynamic queries in Entity Framework.
