Pity you guys didn't release this POCO stuff last month. You could have saved me a large workaround. Never mind. Still, this is very handy. I need to come back to this. Glad to see the constant stream of improvements comming out.
Could you say a little about serialization and the efficiency of using POCO over RIA Services? What's going on in terms of the TCP/IP packets? I like the features (security, attributes, validation), but would like to get a feel for what the trade-offs are.
The comparison is slightly unfair, but lets say we used custom .ashx handlers instead. What is the overhead assuming we use the same serialization method underneath?
