According to this link of another question of mine that ended up generating error where I followed the steps referring to another question, I'm having a rather strange error.

I created a partial to do the manipulations in the Telephones table of my project. But it simply is not rendered in any way ... It should appear in the create and edit of the student data.

I'll put the codes I used:

View Create (and that of edit , which is the same thing)

@model SisGAL.Models.Aluno

@{
   ViewBag.Title = "Create";
}

<h2>Create</h2>
