I integrate Episerver Forms add on into my project which is using Webforms technology. I have found that Episerver Forms support MVC based websites. so i need help to know how can i made the Episerver Forms add on work with my WebForms based website. Thank you !
Episerver Forms is only supported by MVC projects: "Episerver Forms is only supported by MVC-based websites and HTML5-compliant browsers."
See the note under gettings started: https://world.episerver.com/documentation/developer-guides/forms/
So if you were looking for information how to make it support webforms based site - there is no official way to do it (and I have not heard of any un-official way). I would say that don't even try to do it - any update could break your "hack" - if you are using webforms then your option is the old XForms: https://world.episerver.com/documentation/developer-guides/CMS/forms/xforms-legacy-functionality/ (NuGet: https://nuget.episerver.com/package/?id=EPiServer.XForms )
I wrote a blogpost about this while back, it was for Episerver 9, but it still might work
