Because youre using an ItemTemplate, theres no need to add TreeViewItems to the tree. Not so important: Create DLL which can open DLL with unit tests and finds fixtures, test methods and actions (more smaller level of unit test, written in our company) using reflection. Your ItemTemplate is trying to render a 'Name' and 'Age' property in TextBlocks, but TreeViewItem doesnt have an 'Age' property and you arent setting its 'Name'.
