title: Post FromBody Always Null
body: <p>I've got a new API that I'm building with ASP.NET Core, and I can't get any data POST'ed to an endpoint.  </p>
  
  <p>Here's what the endpoint looks like:</p>
  
  <pre><code>[HttpPost]
  [Route("StudentResults")]
  public async Task&lt;IActionResult&gt; GetStudentResults([FromBody]List&lt;string&gt; userSocs, [FromBody]int collegeId)
  {
      var college = await _collegeService.GetCollegeByID(collegeId);
      // var occupations = await _laborMarketService.GetOccupationProgramsBySocsAndCollege(userSocs, college);
      return Ok();
  }
  </code></pre>
  
  <p>And here's what my payload that I'm sending through Postman looks like:</p>
  
  <pre><code>{
      "userSocs": [
              "291123",
              "291171",
              "312021",
              "291071",
              "152031",
              "533011"
          ],
      "collegeId": 1
  }
  </code></pre>
  
  <p>I'm making sure that I have postman set as a POST, with <code>Content-Type  application/json</code>.  What am I doing wrong? </p>
