This eliminates the need for workarounds when handling inheritance hierarchies in JSON processing. The feature uses a discriminator field to identify the correct derived type during deserialization, making it easier to work with polymorphic objects in APIs, message processing, and document storage scenarios. 38 2 2. 2 [](https://daily.dev/posts/mastering-dependency-injection-in-net-core-a-complete-beginner-to-advanced-guide-ah8yy63ml "Mastering Dependency Injection in .NET Core: A Complete Beginner-to-Advanced Guide") Article C# Corner · 1y Mastering Dependency Injection in .NET Core: A Complete Beginner-to-Advanced Guide Dependency Injection (DI) is a design pattern that promotes loose coupling, testability, and maintainability in .NET Core applications. The guide covers service registration in Program.cs, constructor injection, three service lifetimes (Transient, Scoped, Singleton), testing with mocked services, and advanced scenarios including factory-based registration and third-party containers like Autofac. Best practices include preferring interfaces over concrete classes, avoiding service locator patterns, and organizing registrations by feature modules. 18 3. 3 [](https://daily.dev/posts/integrating-react-with-asp-net-core-8-in-visual-studio-2022-zimzl2pht "Integrating React with ASP.NET Core 8 in Visual Studio 2022") Article C# Corner · 1y Integrating React with ASP.NET Core 8 in Visual Studio 2022 Learn how to build a full-stack application by integrating React frontend with ASP.NET Core 8 Web API backend using Visual Studio 2022\.
