Using entity framework core in .net

Entity Framework Core (EF Core) is an object-relational mapper that reduces friction between data structures and classes, builds and executes SQL queries, and allows querying and updating data. It is cross-platform, supports LINQ queries, change tracking, and schema migrations. A database context provides logic for EF Core to interact with the database by exposing database sets and determining how EF Core handles data at runtime. Common methods like OnConfiguring and OptionsBuilder are important for configuring the connection string and database provider. EF Core supports databases like SQL Server, SQLite, MySQL, and PostgreSQL.
