Keyed Services in ASP.NET Core | Dependency Injection Explained with Examples in .NET 8

Are you struggling with multiple implementations in .NET Dependency Injection? In this video, I’ll explain Keyed Services, a new feature introduced in .NET 8 and C# 12 that allows you to register multiple service implementations with unique keys. This feature is especially useful in ASP.NET Core applications to resolve dependency conflicts. We'll start by demonstrating the common issue of overriding services in DI, then implement Email and SMS notification services to show how Keyed Services solve this problem. By the end of this tutorial, you'll understand how to use AddKeyedScoped, inject services with [FromKeyedServices], and write cleaner, more maintainable code in ASP.NET Core.
