Deleting in EF Code first causes navigational properties to be set to null and empty?

This is how EF works. The problem is that your Playlist forms entity graph with other relations and EF uses very simple rule for tracking entity graphs: All entities in the graph must be tracked - there cannot be reference to entity which is not tracked. I don't give you reference to description of this rule, it is just my observation but I didn't find any single exception to this rule.

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.
