We just released a beta version of the Telerik OpenAccess Data Services wizard.
I suggest you to try it out, there are a lot of old issues solved there and we also added a VB support.
If you have Astoria 1.5 installed on your machine you can use Astoria 2 Services as well.
We also solved the WCF cyclic reference with the generated WCF services and we have plansto support RIA services in furthure releases too.
You can get the latest update from here:
Please let us know if you have any more issues.
