Auth0 implementation for Razor pages

Hi, I see lot of sample codes for MVC and other implementations of Auth0. I am looking for help with Auth0 and Razor pages example that I can refer. Also, I want to implement login feature without having means to login(like a page or a button), it should be more like as the user enters the razor we app , they should be able to see Hello ________ and not a login button or page. And I want to authorize entire application i.e. all the pages and do not want to implement code to authorize from each page because the parameters that I fetch from JWT token I wanted it to be accessible through-out the appplication.
