File Based Routing for Minimal APIs/Blazor

[divyeshio]

Starting a new project with minimal apis is great experience, but as projects grows apis require structuring. Wouldn't it be great if the structure of the files/folders depicted the routes. Frameworks like Next.js and Tanstack already have this feature. And it is a great experience indeed. Was wondering if we could have something similar in .Net, it would make the DX even better.

Some addtional features :

• Scaffolding : In Tanstack router, when you create a new file in routes folder, it generates writes code that is used for routing something like scaffolding, may be we can use source generators for this.
• Type safe routing : You get typesafety when you're referring to routes from anywhere in the application. Once you have used it, you will miss this feature everywhere. Might not be much useful in minimal apis but could be useful in Blazor (quickly looked up Navlink can use it)

@davidfowl PTAL and share your thoughts here (I think you checked such approaches before when IIRC).
