Now, I am seeing something that is new for MSDN Documentation, not only similar clarity but actual guidance on when Microsoft suggests to… read moreASP.NET 4.0 Dynamic Data and Many to Many Entity Framework Entities
November 07 2009
Even though I’m a much bigger fan of distributed apps than using UI bound data binding, it’s still important for me to know how these various tools work – especially since I need to write about them in my updated E.F. book. ;) I did not play much with Dynamic Data… read moreLost Newfie (dog) in Bedford Mass

October 30 2009
In EF v1, it is possible to have one way navigations where you have an association between two entities but a navigation in only one of them. But the designer didn’t support this. If you deleted a navigation, the association was automatically removed. You could, however, go into the XML and… read moreScreencast – What’s new in the Entity Data Model Designer in VS2010

October 21 2009
There are two changes to the lazy loading feature introduced in the Beta 1 version of Entity Framework. The first is that the property, ObjectContext.ContextOptions.DeferredLoadingEnabled has been changed to ObjectContext.ContextOptions.LazyLoadingEnabled. This is a breaking change from Beta 1 and you’ll need to update references to this property. The bigger change is that LazyLoadingEnabled… read moreEF4: Syncing Foreign Keys and EntityReference.EntityKey
October 20 2009
In EF version 1, a reference entity and it’s related EntityReference.EntityKey stay in sync when you change one or the other. E.g., if you have a sales order, it’s Customer property and the CustomerReference.EntityKey are automatically kept in sync by the ObjectContext. What happens as we introduce foreign key values into the… read moreSome Tidbits of Entity Framework 4 in Visual Studio 2010 Beta 2
