I was busy with a(nother) comparison of Castle ActiveRecord and the Microsoft offerings that have shipped with VS2010 just to make sure that I wasn’t missing out on anything. I ended up fiddling with EDMX files, and then custom generation, which then led me to downloading the ADO.Net POCO T4 generation templates and checking out what was in the files.
I have to admit: when I saw what was in it, I got quite giddy with excitement, followed shortly by feeling like a tool. I can’t believe I’ve missed out on this excellent piece of functionality that has been around...
