title: Receiving Json deserialized object as string in Web API controller
body: <p>Following is my Json input from Ui:</p>
  
  <pre><code>{
      "data": [{
          "Id": 1
      }, {
          "Id": 2
      }, {
          "Id": 3
      }]
  }
  </code></pre>
  
  <p>I can receive it without an issue in the object structure shown below:</p>
  
  <pre><code>   public class TestController : ApiController
      {
          /// &lt;summary&gt;
          /// Http Get call to get the Terminal Business Entity Wrapper
          /// &lt;/summary&gt;
          /// &lt;param name="input"&gt;&lt;/param&gt;
          /// &lt;returns&gt;&lt;/returns&gt;
  
          [HttpPost]
          [Route("api/TestJsonInput")]
          public string TestJsonInput([FromBody] TestInput input)
          {
              return JsonConvert.SerializeObject(input.data);
          }        
  
          public class TestInput
          {
              public List&lt;Info&gt; data { get; set; }
          }
  
          public class Info
          {
              public int Id { get; set; }
          }
  
      }
  </code></pre>
  
  <p>However my objective is to receive in following API method:</p>
  
  <pre><code>      [HttpPost]
          [Route("api/TestJsonInput")]
          public string TestJsonInput1([FromBody] string input)
          {
              return input;
          }
  </code></pre>
  
  <p>Reason for this requirement is, I have no use of the Json object de-serialized via Web API, I just need to persist the actual Json to the Database and fetch and return to Ui, which will parse it back.</p>
  
  <p>As I am not able to receive in the string input as suggested, so I have to carry out extra step of Json serialization, de-serialization to achieve the objective. Any mechanism for me to avoid this workaround totally by receiving in a string and using it directly. I am currently testing using Postman</p>
