I found the problem. An [XmlElement] attribute is required for elements that are lists. public class ItemGroupClass { [XmlAttribute] public string Label { get; set; } = string.Empty; // ......

Here you go. The Visual Studio project file. [HsDragon TestFile.zip](https://github.com/Cinchoo/ChoETL/files/7965261/HsDragon.TestFile.zip) The POCO object file. [MsbProjectItem.zip](https://github.com/Cinchoo/ChoETL/files/7965264/MsbProjectItem.zip)

Thank you so much for your help! It would have been impossible for me to figure that out on my own without doc. I think VStudio *requires* that xmlns line,...

I confirm that your suggested fix worked when I upgraded from ChoETL 1.2.1.28 to 1.2.1.42. Now I have a different problem - with the classes all decorated with a namespace...

Just FYI, I read somewhere that the xmlns attribute is optional in project files now.
