WCF Service Operation does not expose data as queryable?

If the BussinesObject is not recognized as entity, the service operation will be treated as if returning IEnumerable instead. For the querying to work the service operation must return IQueryable where T is an entity type. Assuming either EF or Reflection provider an entity type is a type which has a key property (either by heuristic or through DataServiceKey attribute) and for which there's a property on the context class of type IQueryable.

If the BussinesObject is not an entity, WCF Data Services can't support queries on the result of the service operation. There are many reasons, to name just one: in order to serialize the response each object must have a unique URL (it's atom:id), to be able to generate a unique URL the object must have key properties. And key properties can only be defined on entities.

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.
