title: Migration in Entity Framework Core - not updating the database
body: <p>I am using a domain first approach. I created an asp.net core MVC project and added a Products.cs in the model folder</p>
  <pre><code>  Products.cs
     -----id
     -----Name
     -----Rate
  </code></pre>
  <p>Now I ran the following commands in package manager console</p>
  <pre><code>  add-migration addedProducts
    update-database
  </code></pre>
  <p>There are no errors in the console manager</p>
  <p>A database was created in the MS-Sql server
  Now I add another entity in the Models folder called Audit.cs</p>
  <pre><code>  Audit.cs
     --- public int Id { get; set; }
      public string UserId { get; set; }
      public string Type { get; set; }
      public string TableName { get; set; }
      public DateTime DateTime { get; set; }
      public string OldValues { get; set; }
      public string NewValues { get; set; }
      public string AffectedColumns { get; set; }
      public string PrimaryKey { get; set; }
  </code></pre>
  <p>Now I repeat the steps in the package manager console</p>
  <pre><code>  add-migration audit
    update-database
  </code></pre>
  <p>There are no error messages.</p>
  <p>I dont see a table called Audit in the database.
  Am I missing something?</p>
