title: Json does not contain a definiton for 'stringify'?
body: <p>I am trying to update a JIRA issue using Visual Studio 2015, Microsoft Razor, and C# with Json.Net 10.0.2. The code is:</p>
  
  <pre><code>public String updateJiraIssue(object objJira2) {
      JiraService.open("PUT", JiraUrl + "/rest/api/2/issue/NPI-24");
      JiraService.setRequestHeader("Content-Type", "application/json");
      JiraService.setRequestHeader("Accept", "application/json");
      JiraService.setRequestHeader("X-Atlassian-Token", "nocheck");
      JiraService.setRequestHeader("Authorization", "Basic " + GetEncodedCredentials());
      var myJSON = Json.stringify(JiraJson);
      JiraService.send(myJSON);
      String response = JiraService.responseText;
      JiraService.abort();
      return response;
  }
  </code></pre>
  
  <p>The error occurs in:</p>
  
  <pre><code>var myJSON = Json.stringify(JiraJson);
  </code></pre>
  
  <p>The JSON is:</p>
  
  <pre><code>string jsonString = @"{""fields"":{""customfield_12302"":{""name"":""xyz""}}}";
  </code></pre>
