John Papa has posted the Table of contents related to his new book “Data and Services with Silverlight 2” now available for pre-order on Amazon.

Check out the original post by Arun Gupta.

In this great post Eugene Osovetsky answers the following questions:

• Why are exceptions not “propagated” from WCF services to Silverlight clients?
• Why are SOAP Faults not supported?
• Given the limitations on exceptions/faults, are there any tricks I can use to make my scenario work? Is anything planned to improve this in the future?
• I can’t even get basic error handling to work when calling web services in Silverlight. Can I at least tell when something went wrong, even if I can’t access the exact fault details?

I’ve just updated the sample about Duplex Services and SLB2: the modified Web.config now permits to expose composite types to the client.

Peter McGrattan has posted three great articles about Duplex support in Silverlight:

• Silverlight 2 WCF Polling Duplex Support – Part 1: Architecture;
• Silverlight 2 WCF Polling Duplex Support – Part 2: The Server;
• Silverlight 2 WCF Polling Duplex Support – Part 3: The Client.

Take a look at this great discussion on the Silverlight forum, about Web-Services interoperability.

As described, Web-Services must be implemented following the specifications reported on the WS-I Organization site.
