Hi All,

I have found a good sample to consume ADO.NET Data Services using SIlverLight 2.0 - here it's:

Using Silverlight 2 With ADO.NET Data Services

http://msdn.microsoft.com/en-us/magazine/dd569758.aspx

I will try to make something like that live tomorrow - time to sleep here.

Thank you.

> But I have found that SilverLight 2.0 doesn't support ADO.NET Data Services "out-of-the-box" as straightforward as the above sample code. This sample code doesn't even compile for SilverLight projects because those projects can't be used with .NET Framework 3.5.

"Not data" services are developed using Windows Communication Foundation (WCF) (and ADO.NET data services are also driven by WCF services AFAIU)...
