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.
