I created a small PowerShell GUI using WPF Toolkit extension.

The GUI works on Visual Studio. However, I got the error "Specified class name 'GUI_test.MainWindow' doesn't match actual root instance type 'System.Windows.Window'. Remove the Class directive or provide an instance via XamlObjectWriterSettings.RootObjectInstance." when I put the XMAL into PowerShell.

Here is the PS code.

I did some research and tried to add custom DLL file (Add-Type/[reflection.assembly]) but did not work. Any ideas would be appreciated.

You need to Remove the x:class... And mc:Ignorable="d" and try again

Hi, vacano

Thanks for your suggestion.

I removed x:Class="GUI_test.MainWindow" and mc:Ignorable="d" but got another error "Cannot create unknown type '{}DateTimePicker'."

Any ideas?
