I am just starting out on my personal project with Mono & Postgres. Your input & views have been invaluable. Thanks a ton. I'm also adding mono-list to the loop, so that they can consider adding support for these frameworks.
I am currently familiar with just ADO.NET, and I think the best option for me is to use Castle.ActiveRecord with nHibernate. Comments/opinions welcome. During my research, this is what I had chanced upon: http://www.howtoselectguides.com/dotnet/ormapping/ I found this post interesting: http://tanveerbadar.wordpress.com/2007/10/14/linqentity-framework-vs-nhibernate/ but think it is outdated, since nHibernate has a LINQ subproject.
