Model.Content IPublishedContent does not contain a definition for "Content"

Questions

Hi, why am I not able to access “Content”, am I missing a reference?

In my view:

@inherits Umbraco.Web.Mvc.UmbracoViewPage
@{
    Layout = "kund_unikum_master_t.cshtml";

    var currentPage = Model.Content;
}

I get the error

“IPublishedContent does not contain a definition for ‘Content’ and no
extension method ‘Content’ accepting a first argument of type
‘IpublishedContent’ could be found (are you missing a suign directive
or an assembly reference?)”

Best regards /David
