Hi everyone,
I need to get advice about in Registration Page in Asp.net MVC5 and razor page.
what is the best way for it:
My scenario is I have a registration process in three-step :
In the First Step, the client enters a username and captcha.
In the Second Phase client Enter the Phone number and send SMS by Identity.
If the Entered validation code was code the confirmation message and welcome page appears.

An easy way is we can make a three action result by the separate razor view.
But the problem is I need to do the noted process without any page refreshing.
what is the best way to do it?
thanks a lot.

What I have tried:

I've implemented it by three action result and razor page
