Help ! Unknown Type

[OscarDelta59]

Hi there,

I'm a Newbee using VB, WPF apps and Mahapps. I need to create some powershell scripts (no problem with powershell), and want to offer a Modern GUI ...

I've followed the How to guide.

Everything is ok in VB :

However, using Powershell, I get this error :

Exception lors de l'appel de « Load » avec « 1 » argument(s) : « Impossible de créer le type inconnu '{http://metro.mahapps.com/winfx/xaml/controls}MetroWindow'. »

I've googled it for hours, without success.

The PS1 file :

`clear-host

[System.Reflection.Assembly]::LoadFrom('C:_TestAppWpf\Metro\MahApps.Metro.dll') | out-null
[System.Reflection.Assembly]::LoadFrom('C:_TestAppWpf\Metro\System.Windows.Interactivity.dll') | out-null
[System.Reflection.Assembly]::LoadFrom('C:_TestAppWpf\Metro\ControlzEx.dll') | out-null

function LoadXml ($FileName) {

$XamlLoader = (new-object system.Xml.XmlDocument)
$XamlLoader.Load($FileName)
return $XamlLoader
}

$XamlWindow = LoadXml("C:_TestAppWpf\test.xaml")
$Reader = (New-Object System.Xml.XmlNodeReader $XamlWindow)
$Form = [Windows.Markup.XamlReader]::Load($Reader)

$Form.ShowDialog()`

The XAML file :

`<Controls:MetroWindow x:Class="MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

Versions : Windows 11 22H2, Visual Studio 17.5.1, Mahapps Metro 2.4.10

Thank you for your help.

Kind regards,
Oliver.

What's your error? I'm getting: | Exception calling "ShowDialog" with "0" argument(s): "Cannot create unknown type '{http://metro.mahapps.com/winfx/xaml/iconpacks}PackIconMaterial'."

IconPacks is installed I guess?
