Hi experts,
I have a bunch of WCF services which use DataContracts in their
interface. We tried using the built-in serializer in NETCF and
encountered that it is really bad in performance in deserializing
larger pieces of data :(
So we went to look into protbuf-net...
But I am not sure how I should use it on the NETCF side. Things seem
to work fine on the WCF 'server' side (using
Serializer.Serialize<List<Product>>(ms, products.ToList());) and the
data gets transferred to the NETCF client.
But if I then try to do this in the NETCF client:
var p = Serializer.Deserialize<List<Product>>(responseStream);
I get this exception:
---
ProtoBuf.ProtoException was unhandled

Well, of course DataContracts do not exist in NETCF so I went along
and generated XmlSerializer-compatible types for the NETCF app with
the netcfsvcutil.exe tool.
And obviously protbuf-net can not handle this now...
What should i do? :)
Thanks!
