New Post: Custom collection support broken in EF6 beta1

@sgifford Thanks for reporting this! I have created the following work item for it: https://entityframework.codeplex.com/workitem/1566

The workaround is to set the navigation property in the entity constructor so that EF will not attempt to create an instance of the custom collection class. For example:

class MyMasterObject 
{
  public MyMasterObject 
  {
    Details = new MyCollection();
  }
 
  public virtual MyCollection Details   { get; set; } 
}
