I am upgrading a site from 7.1 to 7.5(7.8) and notised that one thing I use is gone in 7.5 and that is PreviewUrl, I use this one:
public static string PreviewUrl(this EPiServer.Core.PageData pageData, EPiServer.Core.PageReference specificVersion, string languageName, string latestUrl) Member of EPiServer.UI.LinkExtensions
Resharper suggest me to use this one:public static string PreviewUrl(this EPiServer.Core.IContent content) Member of EPiServer.Cms.Shell.IContentExtensions
But that one does not have the possibility to send along a pageref and languagename.Anyone knows what is a good replacement for the old one (can't find it in breaking changes document)
You might want to check out UrlResolver class and more specifically the method GetUrl that accepts VirtualPathArguments. VirtualPathArguments has a property to set for specifying contextmode.Preview. That should take care of it...
