We recently upgraded our project to Sitecore9 initial release from 7.2. We were re-compiling our code including latest Sitecore.Analytics.dll
We are getting this error
if (Tracker.IsActive) { Tracker.Visitor.ExternalUser = domainUser.ToLower(); }
Method not found: 'Sitecore.Analytics.Data.DataAccess.Visitor Sitecore.Analytics.Tracker.get_Visitor()'.
Can someone help me in resolving this?
