Simple Injector

Simple Injector is a lightweight, high-performance dependency injection (DI) container library for .NET applications. It focuses on providing a simple, fast, and flexible way to manage object dependencies and promote loose coupling in code. It supports advanced features like property injection, decorators, and conditional registrations while maintaining a small footprint.

Also known as: SimpleInjector, Simple Injector DI, SimpleInjector Container, SI, Simple Injector Library

Why learn Simple Injector?

Developers should use Simple Injector when building .NET applications that require efficient dependency injection, especially in performance-critical scenarios like web APIs or desktop applications. It is ideal for projects needing a container with minimal overhead, strong compile-time verification, and support for complex dependency graphs without sacrificing speed.
