title: Keep getting could not load Microsoft.Data.Edm
body: <p>i am using VS2015 community edition, working on a NopCommerce website, i am working on a plugin, and on my local machine everything works fine as expected, but when i depoly it live i keep getting the yellow screen with " Could not load file or assembly 'Microsoft.Data.Edm' or one of its dependencies. The
  located assembly's manifest definition does not match the assembly reference. "</p>
  
  <p>i do see that there is a version issue, and it tries to load version 5.6.4 from my plugin, and it shows that it loaded 5.7.0</p>
  
  <p>so i tried to reference inside the plugin the older version, and it works for a while but then it crashes until i make a full deployment, and then it works for another while and crashes again.</p>
  
  <p>so i want to get this fix the proper way, but i have no idea why my plugin uses a different version than the whole nop, what i see is that inside the bin folder from the project, i see the dll version of 5.7.0, but i have no clue why my plugin is looking for an older version, can anyone just give me some notes on this?</p>
