Autofac is an Inversion of Control (IoC) dependency injection container for .NET, .NET Core, and ASP.NET Core. It manages class dependencies through component registration, constructor/property/method injection, lifetime scopes, and a flexible module system.

Use cases

• resolve dependencies in a .NET application with an IoC container
• register services and inject them into constructors in ASP.NET Core
• manage service lifetimes and nested scopes in a large C# codebase
• scan assemblies to auto-register components by convention
• organize complex registrations into reusable modules
• replace the default Microsoft.Extensions.DependencyInjection container

When to choose

• you need a mature, feature-rich DI container for .NET with lifetime scopes and assembly scanning
• you want flexible registration via lambdas, types, instances, or modules
• you need integration with ASP.NET Core, MVC, Web API, or other .NET frameworks

When to avoid

• you only need simple DI and prefer the built-in Microsoft.Extensions.DependencyInjection
• you are not working in a .NET/C# environment
