Hi !

I've tried follow instructions form :http://riaservicescontrib.codeplex.com/wikipage?title=T4RIA%20Documentation, but receive an error:

Actually I need WCF RIA Services Contrib for partial save ( adding one entity during ading/editing other) - could someone describe how to use WCF RIA Services Contrib to do it , form configuring Contrib to usage in client side app - some kind "for dumies" instruction, pleeeeaaaseeee !

It is very common scenario in business app, I think - adding some entities durring editing opperation of other entities. In WCF RIA calling SubmitChanges() effects updating whole DataContext, but if there is many changed/added/deleted entities and some of them has validation errors - you are in big trouble, if you want update only correct entities. My only hope is WCF RIA Services Contrib, but I don't know hot to use it - help me !
