There are two approaches you can use:

1)      The EntityReferenceStrategy can be set for a property via the EntityRelationRole via the static EntityRelations defined for each type.  This effects all navigation on this property.
a.  EntityRelations.FK_OrderSummary_Customer.Role1.ReferenceStrategy = EntityReferenceStrategy.NoLoad;
b.  EntityRelations.FK_OrderSummary_Customer.Roles.First(er => er.EntityType ==
   typeof(Customer)).ReferenceStrategy = EntityReferenceStrategy.NoLoad;
2)      You can set the EntityManager.DefaultQueryStrategy = QueryStrategy.CacheOnly]]> Fri, 05 Feb 2010 14:26:58 -700 http://www.ideablade.com/forum/forum_posts.asp?TID=1637&PID=6178#6178 EntityReferenceLoadStrategy : I am evaluating DevForce and do... http://www.ideablade.com/forum/forum_posts.asp?TID=1637&PID=6173#6173 Author: bfoster

I am evaluating DevForce and do not like the idea of the "Getter" automatically loading navigation properties.  I would like to use EntityReferenceLoadStrategy.DoNotLoad and implement my own explicit lazy loading.  However it looks like I would need to change the FetchStrategy to CacheOnly which obviously would not be very usefull. 

Would the world exlpode if I set the load strategy directly (via reflection), or must I resort to code gen?
 
Thanks!
