title: Entity Framework - Cascade Delete not getting set in Entity Model
body: <p>I am using EF 4.0 and am generating my Entity Model (.edmx) file from my database. I have several foreign key constraints for Cascade OnDelete, however, these are not getting set on my associations in my entity model. I click on the association and it shows End1 OnDelete: None. </p>
  
  <p>When I check the Delete rules in my SQL Server 2008 database on my foreign key constraint, it says 'Cascade'. </p>
  
  <p>Is there something I am missing to get the Cascade OnDelete flag to set in my entity model? </p>
