title: The type of namespace 'Logging' does not exist in the namespace 'Sitecore'
body: <p>Added Sitecore.Logging dll (from nuget) in the project but I still get the error.</p>
  
  <p>It was working fine until I added a log4net dll (as part of some other nuget dependency). After this there was an ambiguous reference error. Then when I tried to specify Sitecore.Logging.LogManager/ Sitecore.Logging.ILog I get the error . </p>
