Thanks for the feedback. Looking back on the folder structure. I agree with your ideas regarding folder structure. I will soon be moving the EntityManager to the Domain Model folder.
Regarding the other "modules/components"
1. Data - The simplified use of ADO.NET is separate from a Domain Model and is kept in a separate folder for clear visibility to a consumer of the code.
2. Repository - Similar idea as #1, I sometimes use the Repository as standalone rather than inside of a Domain Model.
Check out the latest sourcecode.. it's got :
1. great examples of many of the components.
2. bug fixes ( offical Beta Build 1 of 0.9.2 version ) is out.
