WCF error service error message with shared classes

Question

Source code: http://code.google.com/p/sevenupdate/source/browse/#hg/Source/SevenUpdate.Base

SevenUpdate.Base.Sui cannot be used since it does not match imported DataContract. Need to exclude this type from referenced types.

Now I tried unchecking reuse reference types and I was able to get my project to compile. but when sending a collection from the client it was never received or couldn't be deserialized on the server end.

I really need this to work. Any help would be appreciated, the fullsource code is provided by google code.

Answer 1

I didnt download the source and build it, but could it be that you are missing DataContract on this class? Sui class has a property of type Sua as DataMember so it will need to be serialized as well. It looks like this in your code currently

[ProtoContract, ]
[KnownType(typeof(ObservableCollection<LocaleString>))]
public class Sua

Answer 2

What would I need to do to reproduce this error? The first bit (about matching data-contract) sounds like WCF isn't very happy with you, which suggests you have two similar (but different) contracts "in play". If you are re-using the types from a shared library this shouldn't be a problem.

If you do end up excluding the types (and having a different model at the client and server) then it can get a bit tricker, since "mex" doesn't guarantee the positions will remain intact (and indde, they regularly change) - but you can fix this in a partial class, by using a few [ProtoPartialMember(...)] against the type (not pretty but it works).

But I stress - the main problem here seems to be WCF; if that isn't happy such that the code doesn't codegen / compile etc, then my hands are fairly tied (since it won't get as far as talking to protobuf-net).
