I've had a look at these before, with much frustration... see my unanswered post here: http://www.telerik.com/community/forums/orm/general-discussions/concurrency-problem.aspx
I downloaded the BestPractices code sample, but that didn't work yet. It is using a 2008-version of OpenAccess. I updated all references to the 2009.3 version but it still won't compile.
Maybe I can repeat the same question as in the other thread? Why must I go through such a pile of trouble just to get a simple example with a RadListView to work? When using Linq2Sql and a Linq datasource this all works out of the box. I thought that using the OpenAccess Datasource would give me the same productivity boost.
Perhaps I miss something important here, but I get the feeling that there are more RadControl users that are pleased with Telerik offering the OpenAccess ORM, yet are disappointed with it once they start using it. There is a lot of documentation, videos, demos, etc. yet I don't find what I'm looking for. I hope you see this criticism as constructive, because that's how I intend it.
Thanks again for your support.
