oh that would work with the keyed adding/retrieving of the requests/responses… guess you have to wait on the posts about client-side usage

@Awkward Coder

Instead of using the KnownType attribute all over the place, we just register them once before the service starts up and then use WCF’s ServiceKnownType to dynamically fetch the list of known types once before the service is first used.

EntityListRequest : Request
{
Criteria{get;set}
Id{get;set}
}
EntityListResponse : Response
{
IList Entities
}

that’s also covered in a future post

what exactly do you mean with generic entity requests/responses?

Should mention you need to use the ‘KnownType’ attributes on the base ‘Request’ & ‘Response’ types to include all derived types in the client side proxy.

Ignore my last comment…

In other words how does the client know about the structure of ‘GetProductOverviewsRequest’ when it is not explicitly exposed\declared on the interface.

that would work if the client would retrieve its response based on the index of the corresponding request, but you’ll see in a future post that we retrieve the response based on its expected type, not the index.
