Please post the ObjectClrOption ("use"..) statement that you are calling to load the assembly.

WinBatch relies on the CLR hosting's reflection functionality to instantiate classes.  There are a  few classes attributed to block instantiation via reflection.

sorry about that:  I coded (and tested by commenting one or more ClrOptions out). At this point oReader and creader have no issues).

Code: Winbatch
ObjectClrOption("use","System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")
ObjectClrOption("use","System.Windows, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")
ObjectClrOption("use","System.Xml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")
ObjectClrOption("use","System.Xaml, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089")
ObjectClrOption("use","System.Xml.ReaderWriter, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")
ObjectClrOption("use","System.IO, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a")

oReader = ObjectClrNew('System.Xml.XmlReader')
xaml=getxaml()
cReader = ObjectClrNew('System.IO.StringReader',xaml)
oReader.Create(cReader)

oWin = ObjectClrNew('System.Windows.Markup.XamlReader')

Oh, and if it helps, I am trying to redo a .ps1 in WB

Code: [Select]
¿$xaml = @"
<Window
 xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'>

 <Border BorderThickness="20" BorderBrush="Yellow" CornerRadius="9" Background='Red'>
  <StackPanel>
   <Label FontSize="50" FontFamily='Stencil' Background='Red' Foreground='White' BorderThickness='0'>
    System will be rebooted in 15 minutes!
   </Label>

   <Label HorizontalAlignment="Center" FontSize="15" FontFamily='Consolas' Background='Red' Foreground='White' BorderThickness='0'>
    Worried about losing data? Talk to your friendly help desk representative and freely share your concerns!
   </Label>
  </StackPanel>
 </Border>
</Window>
"@

$reader = [System.XML.XMLReader]::Create([System.IO.StringReader] $xaml)
$window = [System.Windows.Markup.XAMLReader]::Load($reader)
$Window.AllowsTransparency = $True
$window.SizeToContent = 'WidthAndHeight'
$window.ResizeMode = 'NoResize'
$Window.Opacity = .7
$window.Topmost = $true
$window.WindowStartupLocation = 'CenterScreen'
$window.WindowStyle = 'None'
# show message for 5 seconds:
$null = $window.Show()
Start-Sleep -Seconds 5
$window.Close()

The System.Windows.Markup.XamlReader Documention (http://msdn.microsoft.com/en-us/library/system.windows.markup.xamlreader(v=vs.110).aspx) states that the required assembly to load is PresentationFramework.dll.

The converted code would look something like this in WinBatch:

I guess the operative expression is "I feel a little less dumb". I like the Xaml and WPF stuff. In fact, I read it has a Grid Class that might be useful to WB.
 
Thanks, as usual. One final question. This stuff does seem to require .NET 4.0/4.5. So, in addition to the check in the script for WB 2013A>,  might make sense to put in a check4netversion() udf? What do you think?

Here is some introductory UDFs to determine dotNet versions installed.
