How to Resolve Multiple Dependency Injection Implementations of the Same Interface in .NET
Are you struggling with registering and resolving multiple implementations of the same interface in .NET or ASP.NET Core? 🤔
In this video, I’ll walk you through practical and production-ready approaches to handle multiple service implementations using Dependency Injection in .NET Core.
Whether you're building scalable enterprise applications or following Clean Architecture principles, understanding this concept is essential for writing flexible and maintainable code.
🔥 What You’ll Learn in This Video:
1. Registering multiple implementations of the same interface
2.Using FromServices in controllers
3. Using Named or Keyed services (latest .NET approach)
4. Best practices for real-world enterprise applications
Why This Is Important?
In real-world applications, you often need multiple implementations for:
1. Payment gateways
2.Notification services (Email, SMS, Push)
3.Logging providers
4.Strategy pattern implementations
5.Multi-tenant or environment-specific services
Handling this correctly improves:
✔ Scalability
✔ Maintainability
✔ Clean Architecture compliance
✔ Testability
If you're preparing for .NET interviews or working on enterprise-grade applications, this topic is a must-know.
