title: C# EF Code First - cascade on update
body: <p>Is there any way to define for 'cascade on update' but not 'on delete', something like this?</p>
  
  <pre><code>   modelBuilder.Entity&lt;Payment&gt;()
                 .HasRequired(s =&gt; s.Customer)
                 .WillCascadeOnDelete(false)
                 .WillCascadeOnUpdate(true);
  </code></pre>
