No it is not possible. EF behaves exactly like database - FK is tight to single relationship with single entity type. Btw.
Navigation property is not FK, FK is hidden behind navigation property but the same is still true - navigation properties cannot be shared among multiple relations.
Use this pattern, which can be achieved by using table-per-type inheritance in EF.
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.
