title: Could not load file or assembly CMS.DataEngine - after Kentico 11.0.0 upgrade to Kentico 12 SP1
body: <p>I have got the following error after upgrading Kentico 11 to Kentico 12 SP1.</p>
  
  <p>The action I have made:
  1. I have removed all the reference of Kentico dll and I added new reference.
  2. All the DLL (both at solution and the published website) in BIN folder and VS belong to version 12, not 11 as written on the error. Also the associated dependency (I have it with ILSPY) .
  3. I removed all the file at C:/Windows/Microsoft.NET/Framework/v4.0.30319/Temporary ASP.NET Files/
  4. I cleared cache and reset IIS.
  5. That assembly doesn't appeared on any file on my solution (even not in WEB.config) .
  6. I check the file of the project Web.csproj and it contain the assembly (CMS.DataEngine) without the version,Culture and PublicKeyToken - I added it like other assembly of kentico
  There is no sign of version 11.0.0.0 , so why the website searching after that version ???</p>
  
  <p>Thank you,
