Could not load file or assembly Newtonsoft.json Version 6.0.0.0

I am trying to update the NewtonSoft to it's latest addition 11.0.1 but when I updated the Dll using NuGet Manager then it started givng me this Error I even Deleted files from all the Temp folders that could be there for the ASP.NEt FrameWork but it seems not to be going away.

  Error:
Reference.svcmap: Could not load file or assembly 'Newtonsoft.Json, Version=6.0.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)   

What else can I try doing here?

Rebuilding the solution usually fixes this error for me
