A marketing mistake: WCF Data Services & WCF RIA Services
The image on the right is from In Search Of Stupidity, an excellent and funny book, which talks about a lot of marketing mistakes that software, dedicate a whole chapter for this error.
Coming back to WCF Data Services & WCF RIA Services, I read this page, and I am still confused. It appears that the major difference in that RIA services will generate the Silverlight client classes as part of the build process, where as using Data Services this is a separate process.
And I am not sure even of that.
