title: The type <type> exists in both 'A' and 'B'
body: <p>Now I know there are a number of these questions already up here, but after flipping through them, I haven't found one that solves my specific problem. </p>
  
  <p>I have an ASP.NET MVC 4.5 project. I used NuGet and added Newtonsoft.Json to the project. As soon as I used it in my code (to do some serialization in camel-case), my project no longer builds correctly with the following error:</p>
  
  <blockquote>
    <p>The type 'Newtonsoft.Json.Serialization.CamelCasePropertyNamesContractResolver' exists in both 'C:..\Microsoft Visual Studio 12.0\Blend\Newtonsoft.Json.dll" and 'C:..\Visual Studio 2013\Projects\myProject\packages\Newtonsoft.Json.6.0.1\lib\net45\Newtonsoft.Json.dll'</p>
  </blockquote>
  
  <p>Unfortunately, it's the same file down to the public key on each so I can't use the dependency assembly reference in Web.config (as suggested elsewhere). I would prefer to use the dll retrieved via NuGet so upgrades to new versions are easier.</p>
  
  <p>Additionally, neither one is in the Temporary Internet folder, so I can't simply delete that and have it work either.</p>
  
  <p>How can I go about specifying the specific assembly file I want to use so I can build the project correctly? Thanks!</p>
