title: Add an extra column to my model in an .edmx file
body: <p>I want to add an extra column, similar to a join to my model based on the ID. Is this possible?</p>
  
  <p>For example:</p>
  
  <pre><code>ProductsModel
  
  ID
  DeliveryID
  
  
  DeliveryModel
  
  DeliveryID
  DeliveryDescription
  </code></pre>
  
  <p>What I'd like to do is add the DeliveryDescription column to my ProductsModel in my .edmx file. I know its possible to add 3 property types (scalar, navigation, complex) are one of these the solution?</p>
