title: Entity Framework .net: "The Name value should be a valid navigation property name."
body: <p>Hello I'm starting a project with ASP.Net and I'm following the Training Camps of Microsoft. I was trying to make a REST petition to my published api, and I got the next exception:</p>
  
  <blockquote>
    <p>The ForeignKeyAttribute on property 'QuestionId' on type
    'PlataformaTest.Models.AnswerModel' is not valid. The navigation
    property 'OptionModel' was not found on the dependent type
    'PlataformaTest.Models.AnswerModel'. The Name value should be a valid
    navigation property
    name.","exceptionType":"System.InvalidOperationException"</p>
  </blockquote>
  
  <p>By the way, I'm not following the Training excercise verbatim, I've changed some names and so, just to try to find out how would be all the process from zero.</p>
  
  <p>Any help and guidance is really appreciated. Thank you.</p>
