What are the best tools for API versioning in ASP.NET Core?

There are several tools and techniques for API versioning in ASP.NET Core, including URL path versioning, query string versioning, and header versioning. Popular libraries include Microsoft.AspNetCore.Mvc.Versioning and NSwag.

Can you explain how to implement URL path versioning?

Sure! To implement URL path versioning, you can define your routes to include the version number, like this: api/v1/products and api/v2/products. You can use attribute routing in your controllers to specify the version.

Query string versioning is flexible and easy to implement, but it can lead to messy URLs and may not be as clear as path versioning. It's useful for clients that need to specify versions dynamically.

Are there any best practices for API versioning?

Yes, some best practices include keeping versioning consistent, documenting your API versions, and deprecating old versions gracefully to avoid breaking changes for users.
