you can find answer on question right here

so, why page method calls have static?

if you’re implementing page methods, you’re aware of excellent performance. performant compared updatepanel’s partial postbacks.

they efficient largely because not require viewstate posted , not create instance of page, while partial postbacks both of these things. know, page method couldn’t create instance of page if desired, since viewstate isn’t provided in request.

this why must marked static.

they cannot interact instance properties , methods of page class, because page method call creates no instance of page or of controls. page methods equivalent shorthand standalone web services. in fact, scriptmanager calls them regular web service.
