title: Could not load file or assembly 'Newtonsoft.Json, Version=3.5.0.0
body: <p>I am working in c# 4.0 to read a signed request I am using the following code</p>
  
  <pre><code>FacebookApp fap = new FacebookApp();
  fap.AppId = "789485219211963"; // App ID
  fap.AppSecret = "365ee9f5823698536767d608cf572a49"; 
  
  string requested_Data = Request.Form["signed_request"];
  FacebookSignedRequest fsr = fap.ParseSignedRequest(requested_Data);
  IDictionary&lt;string, string&gt; myDic = fsr.Dictionary;
  
  string name = myDic["name"];
  string algorithm = myDic["algorithm"];
  
  Response.Write(requested_Data + "&lt;br&gt;" + algorithm + "&lt;br&gt;" + name + "&lt;br&gt;");
  </code></pre>
  
  <p>But on the highlighted line I received following exception</p>
  
  <blockquote>
    <p>Could not load file or assembly
    'Newtonsoft.Json, Version=3.5.0.0,

    one of its dependencies. The located
    assembly's manifest definition does
    not match the assembly reference.
    (Exception from HRESULT: 0x80131040)</p>
  </blockquote>
  
  <p>I downloaded Newtonsoft.Json. release 1 instead of release 2 but it still not working.
  Can someone kindly help me to solve this problem, also please guide me either my way of reading signed request is correct or not if not please specify the correct way.</p>
  
  <p>Thanks:</p>
