<p>What I am looking for is the equivalent of <code>System.Windows.SystemParameters.WorkArea</code> for the monitor that the window is currently on.</p>

<p><strong>Clarification:</strong>  The window in question is <code>WPF</code>, not <code>WinForm</code>.</p>

```
Screen.FromControl
```
,
```
Screen.FromPoint
```
and
```
Screen.FromRectangle
```
should help you with this. For example in WinForms it would be:
```
```
class MyForm : Form
{
  public Rectangle GetScreen()
  {
    return Screen.FromControl(this).Bounds;
  }
}
```
```
I don't know of an equivalent call for WPF. Therefore, you need to do something like this extension method.
```
```
static class ExtensionsForWPF
{
  public static System.Windows.Forms.Screen GetScreen(this Window window)
  {
    return System.Windows.Forms.Screen.FromHandle(new WindowInteropHelper(window).Handle);
  }
}
```
```
