What is a DbSet?
Updated Apr 28, 2026
Short answer
DbSet represents a collection of entities of a specific type in the context, typically corresponding to a database table.
Deep explanation
It implements IQueryable, allowing you to write LINQ queries against the database. When you add, remove, or update entities in a DbSet, the DbContext tracks these changes and pushes them to the database upon calling SaveChanges().
Real-world example
Representing the 'Employees' table in a company database so you can query all active employees.
Common mistakes
- Iterating over a DbSet directly without calling .ToList() or .ToListAsync(), which leaves the database connection open during iteration.
Follow-up questions
- Can a DbSet correspond to a View?
