Laden Sie die WPF-Anwendung aus dem Speicher
So rufen Sie Main () in Nicht-WPF-Anwendungen auf:
var entry = assembly.EntryPoint;
if (assembly.EntryPoint.GetParameters().Length == 0)
entry.Invoke(null, new object[0]);
else
entry.Invoke(null, new object[] { args });
aber irgendwie funktioniert es überhaupt nicht für WPF-Anwendungen, ich habe es versucht (MSDN's Weg):
Assembly asm = Assembly.LoadFrom(file);
Type myType = asm.GetType("WpfApplication1.App");
// Get the method to call.
MethodInfo myMethod = myType.GetMethod("Main");
// Create an instance.
object obj = Activator.CreateInstance(myType);
// Execute the method.
myMethod.Invoke(obj, null);
Immer noch kein Erfolg, Reflector zeigt Main () als
[DebuggerNonUserCode, STAThread]
public static void Main()
{
App app = new App();
app.InitializeComponent();
app.Run();
}
Egal was ich tue, ich erhalte die Ausnahme "System.Reflection.TargetInvocationException".
Irgendeine Hilfe?
PS. Weiteres Debuggen ergab, dass die ursprünglich in der zu ladenden Assembly befindliche Ressource „mainwindow.xaml” nicht geladen werden kann
{System.IO.IOException: Nie można zlokalizować zasobu „mainwindow.xaml”.

Ich vermute, das Problem ist, dass CLR versucht, .xml in der Loader-Anwendung und nicht in der tatsächlichen WPF-Anwendung zu finden.
