Rocky,
In the sample code for the CSLA 3.8 core video series, in the Core380\Data\ObjectFactory\Library\TestObject.cs file, you add a PropertyInfo for the EF EntityKey, which, if I understand correctly, is useful in preventing a round-trip to the DB during updates.
My question is, why do you set that PropertyInfo to type "byte[]", which forces you to Serialize/Deserialize it, instead of just using System.Data.EntityKey ?
Thanks
If I use the EntityKey type, then all my code needs to reference EF, even client-side libraries and things that shouldn't have to have such a reference.
That couples my entire app to EF, which is (imo) a bad thing. I want only my DAL to be coupled to EF.
Additionally, it might be that EntityKey isn't serializable? I don't know for sure.
I am reasonably certain it won't serialize to Silverlight, where EF doesn't exist at all.
And that's probably the key - most of my work for a long time now has been Silverlight focused - so things that don't work or exist on Silverlight must be isolated very carefully so they are only used in very controlled parts of the code.
Makes tons of sense 
Thanks
