How .NET Core Handles Different Service Lifetimes
.NET Core's built-in Dependency Injection (DI) system manages service lifetimes as follows.
Singleton: The service is created once and shared throughout the application.
Scoped: A new instance is created for each request (in web apps).
Transient: A new instance is created every time it is requested.
Internally, .NET Core stores services in a service collection and resolves dependencies from a service provider when needed.
Key Differences Between .NET Core's Built-in DI and Third-Party DI Containers
Simplicity: The built-in DI is lightweight and easy to use, while third-party DI containers offer more features.
Flexibility: External DI containers (like Autofac) provide advanced features and better support for complex scenarios.
Performance: The built-in DI is optimized for .NET Core, making it faster for most standard use cases.
