Entity Framework
In plain terms
Microsoft's ORM for .NET applications.
Going deeper
Entity Framework maps C# classes to database tables, letting developers query with LINQ instead of raw SQL. It's the standard .NET data-access layer.
Under the hood
Supports code-first migrations and change tracking; can generate inefficient queries if misused.
Examples
.NET apps, LINQ queries, code-first migrations, ASP.NET data access.
Think of it like...
Like a translator letting your C# objects talk to the database in its own language.
