I've been desperately trying for about the last week to figure out whatever my disconnect is that I can't wrap my head around RIA Services. I've meticulously followed the example shown in the Microsoft tutorial video and I'm still having problems. It may be that I'm trying to do something you can't, but in all likelihood I'm just going a...
I've finally managed to get a handle on loading information using Silverlight, ADO.NET Entities, and RIA Services, but I'm still having a problem with getting the information about the relationships.

I 'm beginning a new web project and was wondering if i could benefit from the "magical" things RIA service can offer, but in a way i was used to develop until now.

I have been getting into RIA services because I thought it would simplify dealing with the services layer of web applications I wish to build. I see lots of examples out there showing how to create DomainService classes which expose and consume entities that have some kind of relational database backing, and therefore have foreign-key re...

When I try to create new sample data based on an existing type, I get the following error message: GetType cannot be called with null or empty typeName I tried restarting Expression Blend 4, but without any success.
