Organize dependency injection configurations by grouping related service registrations into reusable extension methods. This encapsulates feature-specific services into modular methods, preventing Program.cs from becoming unmanageable and promoting code reusability.

Register scoped services using Microsoft.Extensions.DependencyInjection by creating an extension method like AddUserServiceCollectionExtensions. This method configures IUserService and IUserRepository with scoped lifetimes, ensuring a new instance is created per HTTP request scope.

Structure large codebases with .NET DI patterns by encapsulating all related service registrations into a single AddFeatureServices extension method. This composable service registration approach maintains modularity and ensures adherence to dependency injection best practices.

Yes, you can reuse production dependency injection configurations in test environments. By structuring registrations into modular extension methods, production DI configurations can be easily reused and overridden during testing to facilitate testability.

Yes, this approach to .NET dependency injection supports managing service lifetimes including Singleton, Scoped, and Transient. It applies to .NET Core and ASP.NET Core applications for structuring service registrations while adhering to Microsoft.Extensions.DependencyInjection best practices.
