ADO.Net Entity Framework An entity object cannot be referenced by multiple instances of IEntityChangeTracker?

Update Because L2E is used you need to save all the linked objects first before you can save the main object. Which makes sense otherwise you would create (in my example) an artist without it's contact object. This isn't allowed by the database design.

/Update.

I've seen this before, you may have to convert the Reference field to an EntityKey before saving and then Load it after its saved. Try this code instead.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
