🔑 .NET Keyed Services Examples

This repository contains examples and usage scenarios of the new Keyed Services feature introduced in .NET 8.

🚀 What are Keyed Services?

In some cases, you may need to register multiple implementations of the same interface and choose between them depending on the context. While factory patterns or IEnumerable<T> injection were common solutions in the past, Keyed Services now provide a cleaner, built-in way to achieve this.

With Keyed Services, you can register services using a key, and later inject or resolve them based on that key.

✅ Key types supported:

• string
• enum
• Type
• custom objects (e.g. record, struct, class)

Examples:

• Traditional : Using IEnumerable<T> to resolve multiple implementations of the same interface.
• Factory Pattern : Using a factory to resolve the correct implementation based on a key.
• Registering With Keyed Services:
  • Keyed Services with String
  • Keyed Services with Enum
  • Keyed Services with Type
  • Keyed Services with Custom Object
