AddDbContext<T>
AddDbContext<T> is an Entity Framework Core dependency-injection extension method that registers a DbContext type and configures its database options.
.NET in Action, Second Edition
AddDbContext is an Entity Framework Core service-registration method that registers a DbContext type with a dependency injection container.
- How it is used
- Configures ASP.NET Core dependency injection so API controllers can receive a request-scoped Entity Framework Core context.
- How deep it goes
- Explains registration, request lifetime, disposal, and constructor injection, but stops short of internal dependency-injection mechanics.
- Examples
- Uses CatalogContext, CatalogController, SQLite startup configuration, database seeding, and injected query operations.
- What you can do after
- Operate/configure ASP.NET Core services with a registered DbContext that controllers can consume safely within requests.

ASP.NET Core in Action, 3e
AddDbContext<T> is an ASP.NET Core dependency-injection extension method that registers an Entity Framework Core database context type and configures its provider and options.
- How it is used
- Registers an EF Core DbContext in ASP.NET Core dependency injection while configuring its provider and connection string.
- How deep it goes
- Explains the options configuration function, provider selection, connection loading, and scoped lifetime without detailing provider internals.
- Examples
- Uses AppDbContext, DefaultConnection, Program.cs, UseSqlite, and the Microsoft.EntityFrameworkCore.SQLite package.
- What you can do after
- Operate/configure an ASP.NET Core application so injected DbContext instances can interact with EF Core and its database.
