Debugging Self Tracking Entities - AcceptChanges exception due to object's key values conflict with another object in the ObjectStateManager?

This usually happens if you try to AcceptChanges on the context which was used to load entities before - use new empty context for accepting changes. AcceptChanges cannot be used when any entity from STE is already loaded in the context - that is limitation of current STE implementation (but it can probably be removed if you rewrite the template).

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.
