title: How to add relationship attributes in entity framework model first?
body: <p>How can I add a relationship attribute in a many to many relationship when I am using a model first approach with Entity framework? </p>
  
  <p>Suppose I have two entities <strong>Entity_1</strong> and <strong>Entity_2</strong> which has a many to many association. Let's assume this association has an attribute <em>attr1</em>. How do I model this in the entity designer in visual studio 2013?</p>
  
  <p>Is there any option to do it or isn't there any option? </p>
