For a long time, I was engaged in projects that didn’t necessitate an understanding of versioning. It was kind of like that toolbox in the garage you never open because everything you need is right there on the workbench. That is, until I had a job interview earlier this year. Out of the blue, they asked me about API versioning, and I was, well, stumped.

That wake-up call sent me on a crash course to fill in the gaps. It’s been a journey and a half, but I’ve managed to pick up a thing or two. And you know what? Why not spread the wealth! This video is my way of sharing everything I’ve learned about API versioning in .NET 7, and how to use it without breaking a sweat.

Understanding API Versioning
Think of API versioning as the secret time machine of the programming world. It allows your API to travel into the future, evolving and transforming, all while ensuring the past — your existing client applications — remain unscathed. With API versioning, you can throw in cool new features, retire the old and rusty ones, or shake up the current structure without causing any hiccups in backward compatibility.

Sounds like a dream, right? But why exactly does API versioning matter?

Well, here’s the deal:

Keeping the Peace (Compatibility)
Picture this: you change your API and suddenly your users are standing in a digital downpour, struggling to adapt to the new changes. Not cool, right? That’s where API versioning comes in. It’s like an umbrella, shielding existing users from the disruption while still letting you introduce your shiny new updates to those ready for it.
Pros: Your users stay dry and happy, even when the API weather changes.
Cons: This method might mean you have to manage and maintain multiple versions of your API simultaneously.

Smooth Sailing (Stability)
With API versioning, developers can keep their apps running as smooth as a top-notch jazz ensemble. It’s like having an always-on-call tech crew to ensure there’s no trouble in the show, contributing to the overall stability of the application.
Pros: Users enjoy a seamless experience with minimal disruption.
Cons: It might take more time and resources to ensure this stability across all versions.

Ready for Tomorrow (Future Proofing)
Software evolution is inevitable, and the APIs driving it need to keep up. API versioning is like your API’s own personal fitness trainer, making sure it stays in shape to keep up with the fast-paced software world, but without leaving any existing users behind.
Pros: Your API stays relevant and up-to-date, ready to take on the future.
Cons: Future proofing with versioning can be a challenging task as you might need to predict how your API will need to change over time.

Final Thoughts
The landscape of API versioning is ever-changing, full of opportunities and challenges. In the context of .NET 7 and future versions, it’s bound to bring even more exciting and groundbreaking developments.
