"cannot create instance defined in assembly" when creating a new System.Drawing.Icon

I am trying to create a system tray icon in WPF using the lines of code below:

System.Windows.Forms.NotifyIcon ni = new System.Windows.Forms.NotifyIcon();
ni.Icon = new System.Drawing.Icon("main.ico");

XAML:

> <Window x:Class="WpfExample.Window1"
>     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
>     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
>     Title="Window1" Height="300" Width="300">
>     <Grid>
>         <Button Height="23" Margin="103,0,100,100" Name="button1"
> VerticalAlignment="Bottom">Submit</Button>
>         <TextBox Height="23" Margin="77,75,81,0" Name="textBox1"
> VerticalAlignment="Top" />
>     </Grid> </Window>

I've searched for a solution on Google but I'm trying to learn WPF and this is a problem I have hit when creating a system tray icon. The message I get is shown below:

Cannot create instance of 'Window1' defined in assembly 'WpfExample, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. Exception has been thrown by the target of an invocation. Error in markup file 'Window1.xaml' Line 1 Position 9.

Can anyone point me in the right direction?

I created a small sample application that displays a tray icon. You can try to run it and study how the code works. I uploaded it to the SkyDrive:

The .ico must be on a standard format, size, colors. I had a issue with this.

Try to get and use this icon file and tell if it work:

There are more icons here:
