Answer 1

Try to do this:

 <TreeView Name="treeView" Margin="5">
    <TreeView.ItemTemplate>
        <HierarchicalDataTemplate ItemsSource="{Binding Path=Folders}" DataType="x:Type ModulesUpToDateChecker:Folder}">
           <Grid>
             <TextBlock Text="{Binding Path=Name}"></TextBlock>
           </Grid>
        </HierarchicalDataTemplate>
    </TreeView.ItemTemplate>
</TreeView>

Answer 2

A HierarchicalDataTemplate is already a DataTemplate (it derives from it). So just skip the ItemTemplate and DataTemplate stuff inside your HierarchicalDataTemplate like so:

<TreeView Name="treeView" Margin="5">
  <TreeView.Resources>
    <HierarchicalDataTemplate ItemsSource="{Binding Path=Folders}" DataType="{x:Type WpfApplication220:Folder}">
      <TextBlock Text="{Binding Path=Name}"></TextBlock>
    </HierarchicalDataTemplate>
  </TreeView.Resources>
</TreeView>

Oh and you have to set the ItemsSource of your treeview either programmatically or in your markup ..

treeView.ItemsSource = ..yourFolderList..
