title: asp.net core 3 axios don't post as expected
body: <p>On the web application client-side, I am using axios to post request.</p>
  <p>Here is my axios post request:</p>
  <pre><code>                axios({
                      method: 'post',
                      url: '/CorporateRequests/PostRequestProcess',
                      headers: { 'Content-Type': 'application/json' },
                      data: JSON.stringify(this.postingModel)
                  }).then(function (response) {
                      if (response.status === 200 &amp;&amp; response.data.status === 200) {
                          window.location.href = &quot;/Service/Process&quot;;
                      } else {
                          self.$parent.showToast('HATA', 'Kayıt işlemi yapılamadı', 'error');
                      }
                  }).catch(function (error) {
                      self.$parent.showToast('HATA', 'Kayıt işlemi yapılamadı', 'error');
                  });
  </code></pre>
  <p>and the url that handle post request from client is like this:</p>
  <pre><code>Task&lt;JsonResult&gt; PostRequestProcess([FromBody]RequestProcessModel postingModel)
  </code></pre>
  <p>but in this way on the controller side I am gettin null postingModel but if I change the <strong>RequestProcessModel  -&gt; object</strong> I can successfulyy get the values from client which the values are below:</p>
  <pre><code>ValueKind = Object :
   &quot;{&quot;requestId&quot;:&quot;026e1be4-f32e-42fe-b60b-4916bc572b0c&quot;,
   &quot;editMode&quot;:false,
   &quot;requestProcessId&quot;:null,
   &quot;requestDetail&quot;:
   [
       {
          &quot;processDetailId&quot;:null,
          &quot;itemId&quot;:&quot;df802578-83b5-4b0a-a4c2-08d72a38df96&quot;,
          &quot;addBill&quot;:true,
          &quot;description&quot;:&quot;&quot;,
          &quot;itemName&quot;:&quot;Kod : KABLO - Adı : KABLO&quot;,
          &quot;price&quot;:&quot;234&quot;
       },
       {
           &quot;processDetailId&quot;:null,
           &quot;itemId&quot;:&quot;ca30ddba-be03-4b75-d7e2-08d738fd2efd&quot;,
           &quot;addBill&quot;:true,
           &quot;description&quot;:&quot;&quot;,
           &quot;itemName&quot;:&quot;Kod : 200 - Adı : üst kapak&quot;,
           &quot;price&quot;:&quot;2343&quot;
       }
  ]
           }&quot;
  </code></pre>
  <p>and this is my <strong>RequestProcessModel</strong>:</p>
  <pre><code>public class RequestProcessModel
  {
      public RequestProcessModel()
      {
          RequestDetail = new List&lt;RequestProcessDetail&gt;();
      }
      public Guid RequestId { get; set; }
      public bool EditMode { get; set; }
      public Guid? RequestProcessId { get; set; }
      public List&lt;RequestProcessDetail&gt; RequestDetail { get; set; }
  }
  
  public class RequestProcessDetail
  {
      public Guid? ProcessDetailId { get; set; }
      public Guid ItemId { get; set; }
      public bool AddBill { get; set; }
      public string Description { get; set; }
      public string ItemName { get; set; }
      public decimal Price { get; set; }
  }
  </code></pre>
