Welcome to Supernova Services! In this article, we dive deep into the differences between .NET 8 and .NET 9 when it comes to creating Web APIs.
In .NET 9, Swagger support is not available out-of-the-box. But don't worry! I’ll show you step-by-step how to add both Swagger and Scalar support manually.
OpenAPI is a standard specification for describing RESTful APIs in a machine-readable format (JSON or YAML).
It defines:
👉 The idea is: any tool or developer can understand your API without needing to see your code, just by reading the OpenAPI file.
Swagger is a set of tools built around OpenAPI. Originally, OpenAPI was called the "Swagger Specification."
Swagger tools include:
Scalar is a modern, elegant API reference UI tool that works with OpenAPI specifications. It offers a clean, beautiful, and feature-rich interface and can even generate client codes easily!
With the rapid evolution of .NET versions, staying updated is key. Learning how to configure and work with Swagger and Scalar manually in .NET 9 gives you an edge in building professional-grade APIs.
If you want to learn .NET development professionally, I offer personalized one-to-one classes covering:

We would like to extend our sincere gratitude and appreciation to Mr. Sudipto of Supernova Services for a tremendous professionalism, for his unique ability in sharing and teaching technical concepts to us!

He really cares about his students, as I have witnessed firsthand, Mr. Sudipto very often went above and beyond the call of duty to assist. He is a great person, very passionate about technologies, with unique talents and ability to teach spanning many different topics and technologies! I wish we could rank his services higher than available 5 stars here, perhaps 50 stars. Mr. Sudipto and Supernova Services, you are the BEST! Thank you for everything!!!

Mr. Sudipto Mukherjee is one of the best instructors I have ever come across. His way of training is nothing short of art. He will teach you why you need or not need to write a piece of code rather than just saying that it should be done, and that makes coding enjoyable and the code very performance oriented. If you want to really learn, you have to really become his friend... He will then take you to the deep end. I am saying this from personal experience.... Just one thing... He does not come cheap, but you get much more than what you have paid for.

Excellent tutor! Let's just say that as a bio-math student, I had next to no experience at coding. A few classes with Mr.Sudipto, and bam! His teaching methods are extremely student-friendly and interactive - The classes are never monotonous, and every new task he presented was an interesting one to look forward to. Within no time, I could write programs of my own. Definite recommend!! 👍🏻
