Hello, Has anyone been trying to use PythonNET to drive a WPF-based application? I am hitting a wall at first step - parsing my XAML with XamlReader. It is failing with a message indicative of bad Xaml, but it is fine (runs in IronPython). Google is proving futile after few hours of searching... any help would be greatly appreciated! Sample Code: # Reference the WPF assemblies import clr clr.AddReference("PresentationFramework.Classic, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35") clr.AddReference("PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35") import System.Windows Application = System.Windows.Application from System.Windows.Markup import XamlReader class XamlLoader(object): def __init__(self, xmlData): self.Root = XamlReader.Parse( xmlData ) def __getattr__(self, item): return self.Root.FindName(item) print "begin run" xamldata = """ <Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="WpfApplication3" Height="300" Width="300"> <Grid></Grid> </Window> """ print xamldata xaml = XamlLoader( xamldata ) my_app = Application() my_app.Run(xaml.Root) print "ending run"
