Silverlight WCF service consuming inherited types in datacontract -

-

I'm trying to consume a WCF service in Silverlight ...

Something that has to be done

    1. The assembly in which all my types Data are marked with contracts, P> a silverlight assembly, which is related to files in the first assembly.

    This means that my .Net app assembly can refer to assembly 1 and my menopause app assembly. It works fine and I can communicate in service.

    Problems occur when I try to transfer classified classified into heritage. IFlight - There is an interface for all types of flights.

    BaseFlight: IFlight - Imports a baseflight flight IFlight

    AdhocFlight: BaseFlight, IFlight - An Adihoke Flight flies off the Basflite and also executes IFlight.

    I can successfully transfer base flight based on the service. However, I really need to transfer the objects of IFlight to the interface because I want an operation contract that can transfer many types of flights ... 

      Public IFlight GetFlightBooking () {AdhocFlight Af = new adhocFlight (); Come back; }

    ... I think that should work?

    However, I get an error:

    "The server did not give a meaningful answer; this could be due to a contract mismatch, a session prematurely off or an internal server error. "

    Any thoughts would be appreciated.

    • I think what you want to do in "normal" .NET WCF is a question here The interface between the WCF service speaks about:

    But I seriously doubt whether it will work in Silverlight or not. There is WCF support sketches in SL, at least to say. I have not tried to do this though I can be wrong.

    oracle - The fastest way to check if some records in a database table? -

    -
    I have a big table to work with. I have to see that there are some records whose parent_id is equal to my passing value. Currently I do this by implementing "my_table using select count (*) where parent_id =: id"; If the result> 0, it means that they exist. Because this is a very large table, and I do not care what the actual number of records present, I just want to know if it exists, so I think count (*) Bit is disabled. How do I apply this requirement most quickly? I'm using Oracle 10. # Tips for Hibernation & amp; Tricks It suggests writing in such a way: Integer number = (integer) session .createQuery ("Select Count (*) to ...."). UniqueResult (); I do not know what is the magic of the unique rule? Why does it fast? To compare, select "1 from mytable where parent_id = passId and rowrum", which is more efficient? If you are not interested in the number of records, then there is an EXISTS query one: Select 'y'
