Powershell forms full window glass transparency - windows

Question

I'm trying to make a powershell windows form all transparent as i was able to get the aero style controls working and hiding the powershell console window this is the only thing missing.
The tutorial I was trying to implement in powershell is this:

You could use the C# sample itself, by compiling/loading it in PowerShell. Sample (untested):
$def = #"
[StructLayout(LayoutKind.Sequential)]
public struct MARGINS
{
public int left;
public int right;
public int top;
public int bottom;
}
[DllImport("dwmapi.dll")]
public static extern bool DwmIsCompositionEnabled();
[DllImport("dwmapi.dll")]
public static extern void DwmExtendFrameIntoClientArea(IntPtr hwnd, ref MARGINS margins);
"#
#Load/Compile C# P/Invoke code
Add-Type -Namespace stackoverflow -Name Aero -MemberDefinition $def
#Check if Aero is enabled on this computer
If([stackoverflow.Aero]::DwmIsCompositionEnabled()) {
#Get mainwindowhandle for powershell console process
$hwnd = (Get-Process -Id $pid).MainWindowHandle
#Define margins = how much extra space to make transparent
$margins = New-Object -TypeName 'stackoverflow.Aero+MARGINS'
$margins.top = 50
$margins.bottom = 0
$margins.left = 0
$margins.right = 0
#Make powershell-console partly aero.
[stackoverflow.Aero]::DwmExtendFrameIntoClientArea($hwnd, $margins)
}
