Quick .NET API Validation Demo with DataAnnotations + REST Client

Learn how to add simple server-side validation in a .NET Web API using DataAnnotations. In this quick demo, I show the input model, the controller logic, and how the API responds with validation errors when the request is invalid. To test the API directly from Visual Studio Code, I use the REST Client extension. You can install it here: https://marketplace.visualstudio.com/... This extension lets you create .http files and send requests without leaving the editor — perfect for quick API testing. If you want to explore all available validation attributes in .NET, check the official documentation: https://learn.microsoft.com/en-us/dot...
