I just download the new version of Orchard1.6 and build that in VisualStudio 2010 but I cannot build, it gives the following error:
Assembly 'Orchard.Web, Version=1.6.0.0, Culture=neutral, PublicKeyToken=null' uses 'System.Web.Mvc, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' which has a higher version than referenced assembly 'System.Web.Mvc, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
If you have a solution for this problem, please share it.
