ASP.NET MVC specific:

You can get this error in an MVC 6 controller if you forget to put [FromBody] in a POST method.

    [HttpPost("[action]")]
    public void RunReport([FromBody]dynamic report)
    {
        ...
    }

The .NETCore default project already includes Microsoft.CSharp reference but you get pretty much the same message.

With [FromBody] added you can now post JSON and then just dynamically access the properties :-)
