WCF Service Reference does not reuse types in existing assemblies (VS 2010 Beta 2)

Question

I\'m looking for the best approach to share types (the actual classes, not proxies) between a WCF service and a client. To that end, I defined the classes in a separate assembl

Answer 1

I did two things in the same step. Not sure if one or both resolved the problem:

1. Added a [DataContract(Namespace="My.Shared.Assemblys.Namespace")] to one of the classes in the shared assembly.
2. Restarted VS 2010 Beta 2

Answer 2

My issue with VS2010 SP1 was trying to use a class that derived from Dictionary<T,U> with a CollectionDataContract attribute. Seems VS won't reuse the type... I also tried Eric's suggestion above, but it didn't work.

Answer 3

Had the same issue, but the I forgot to build assembly with DataContracts for client and thus it was generating it's own contracts. Once I've rebuilt the assembly - it reused them.
