Ef4 cause Circular reference in web service?

There are multiple solutions for your problem and they really depend on the type of service you are using and on the type of serialization.

I usually write specific classes for the webservice. While this is some extra work it has the advantage that the webservice gets more robust as small changes in your entities won't go unoticed and silently fail on the side of the consumer/javascript. For example if I change the name of a property.

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.
