c# - How to use Resources.resx to link images

Question

I have included an icon file inside my Resources.resx that I'd like to show on a TreeViewItem that is inside a stackpanel.

1)Can .ico files be used for this purpose? Or does it have to be .bmp or jpg?

2)What do you set the source as in XAML? The following code didn't work for me

<StackPanel Orientation="Horizontal">
    <Image Margin="2" Source="/Resources/Folder_Back.ico" />
    <TextBlock Margin="2" Text="{Binding ProgramName}"
     Foreground="White" FontWeight="Bold"/>
</StackPanel>

Here is a trick to access image in Resource file:

Accessing image from Resource File in XAML markup

First you need to add reference to project properties like this:

xmlns:properties="clr-namespace:MyProject.Properties"

And then access it via XAML like this:

<image source="{Binding Source={x:Static properties:Resources.ImageName}}" />

You can use PNG/JPG/BMP as well as ICO file but everyone recommend PNG.
