Could not load file or assembly 'Newtonsoft.Json, Version=4.5.0.0, 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)
There is already NewtonSoft.Json.dll with version 6.0.0.0 present in the bin folder.
Since NewtonSoft.Json.dll is also referenced by System.Web.Http and version of that is 4.5.0.0
And there is also the following code in web.config
<dependentAssembly>
<assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad4fe6b2a6aeed" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-6.0.0.0" newVersion="6.0.0.0" />
</dependentAssembly>
Followed this solution but didn't help Newtonsoft.Json Assembly Conflict
