My current project (soon to finish) involved using Entity Framework over WCF. We ran into some issues with this approach (primarily around complexity involved with handling detached vs attached objects) so I thought I'd have a look at DevForce EF / WinClient.
Can someone point me to a simple n-tier sample application? Something that supports pulling back multiple instances of an entity (for display) and then insert / delete / update functionality. This would be very helpful in investigating whether the kind of issues we had with vanilla WCF / EF would be overcome with DevForce.
I recently watched IdeaBlade's Silverlight video from MIX09 - that kind of sample would be perfect (but with WinForms (preferred) or WPF client, accessing middle tier over WCF, with middle tier accessing SQL Server backend). Note that what it 'looks' like doesn't matter - but it does need to be reasonably easy for me to change / fiddle with (to allow some level of comparison with our existing approach).
