More WCF services

.NET RIA Services  and ADO.NET Data Services will be rebranded as WCF Data Services and WCF RIA Services. That seems to be an interesting marketing move, but in fact it express that WCF was and is major base technology for communication.

RIA Services and Data Services are a bit different than their base WCF. If you will they totally hide away the complexity of using WCF directly. The power of WCF is still there for you under the covers, if you need to modify some setting to your liking.

New Binding in Silverlight

Silverlight 4 will provide a new high-performance binding NetTcp.with duplex support.In Silverlight, the binding is built on top of the sockets support that’s already there since Silverlight 2.
Because of this the security requirements inherit security requirements of the Silverlight sockets API. That means, services need to be hosted in a given port range 4502 – 4534 and needs to expose a policy responder on port 943.

Note that streamed programming model for NetTcp in SIlverlight is not supportel like in desktop framework.
