Understanding Swagger & OpenAPI in .NET 10 | Practical ASP.NET Core Setup
While working with ASP.NET Core APIs, most developers use Swagger regularly — but many are still confused about the difference between Swagger and OpenAPI.

So I created a practical video explaining:

• What Swagger actually is
• What OpenAPI does internally
• Difference between Swagger and OpenAPI
• Why .NET 10 provides OpenAPI support by default
• How to manually enable Swagger in Visual Studio 2026
• API testing using Swagger UI and .http files

I also explained how OpenAPI JSON is generated automatically from controllers and how Swagger UI reads that JSON behind the scenes.

This video is specially helpful for beginners and intermediate backend developers working with ASP.NET Core Web APIs.

Clean Architecture in ASP.NET Core — Practical Project Setup

Most developers understand Clean Architecture only in theory.

But the real challenge starts when you try to implement it in an actual project.

In this video, I explained the practical setup of Clean Architecture in ASP.NET Core, including:

• Creating a proper solution structure
• Understanding Domain, Application, Infrastructure, and API layers
• Setting up Project References correctly
• Following the Dependency Rule practically
• Difference between Inner and Outer layers
• Industry-standard naming conventions

This video is especially helpful for beginners and intermediate developers who want to build scalable and maintainable applications using .NET.
