Why isn’t Razor Pages more popular?

(To clarify, by “popular”, I mean more widely adopted and advertised when compared to standard MVC and the upcoming Blazor)

My team and I decided to go against the grain and use Razor Pages instead of .NET MVC for a new project, and after working with it for a couple of months, it honestly feels much more easy to understand and maintain than our MVC applications were.

I really like how the page handler methods and endpoints are kept associated in a PageModel which ties directly with the PageView, meaning no more lengthy bloated Controllers to maintain like in MVC.

And that’s just standard Razor Pages. Coupling it with other libraries and frameworks, I feel like it can be really powerful and easy to work with.

Is there something I’m maybe not seeing here?
