Goodbye Swagger, Use This New .NET API Documentation
Is Swagger dead in .NET? With the release of .NET 9 and .NET 10, Microsoft has officially removed Swashbuckle (Swagger) from the default project templates — although you can still use it by manually adding the NuGet package. Now, it's time to explore the new alternative: Scalar — a modern, high-performance solution for API documentation. In this video, we’ll transform a raw OpenAPI JSON specification into a stunning, interactive, Stripe-level documentation UI using Scalar — complete with built-in dark mode and a professional API playground.
What we’ll cover:
🛠️ Native OpenAPI: How to use Microsoft.AspNetCore.OpenApi to generate your spec.
🎨 Scalar Integration: Setting up the Scalar.AspNetCore NuGet package in seconds.
🔐 Security & Validation: Why "hiding" an endpoint isn't enough (and how to do it right).
✨ Pro Customization: Adding XML summaries and a "Back to Home" button.
🧪 Live Testing: Using the built-in REST client to test requests without leaving the docs.
NuGet Packages Used:
Microsoft.AspNetCore.OpenApi
Scalar.AspNetCore
Swashbuckle.AspNetCore
