I'm not going to write a very long story about the DotNED meeting last Thursday, other than that it was great!. 
. Due to time restrictions I only had half an hour for the presentation and the demonstration of LLBLGen Pro, which was too short for me to explain a lot about O/R mapping, its details and how it works in practise, though I hope everyone enjoyed what I had prepared! I've translated my slides to English as well, for the few who want to have them in English.
Some people said the presentation was good but I wasn't as enthousiastic as they expected. I was and am very enthousiastic about O/R mapping and data-access as a subject, I'm just not that experienced in giving presentations (this presentation was my first in years, and my laptop appeared to be very outdated). But that might change in the future, who knows. 
. Either way, thanks for the feedback.
The other presentation given was by Jeroen van Helvoort who made RADvolution Designer, a layout designer toolkit. Now, besides the obvious RAD advantages of the toolkit, one thing that was really great was its naming scheme engine. You could define a naming scheme (like use m_Name_controlType) with a rich set of options and every control you added to the forms automatically adapted that naming scheme. Very clever idea, which should be a core element of Visual Studio.NET as well, for example in the class designer.
Peter van Ooijen made some great pictures of the meeting, he'll write an own review of the meeting as well, so check back on his blog as well later today. One picture he made is shown below, with me in front of the code which fetches all countries from Northwind's Customer table, filters on the selected customer, shows the customers of the selected country in a grid, the orders of the selected customer in another grid and save changes to any object in the graph customer - order - order details! Using LLBLGen Pro of course
