I have a WPF UserControl, which I use in a WinForms Control within an ElementHostControl. Then I start a WPF Window, while the Windows Form is still open. If I then close the WPF Window, and try to add a Child Element to my WPF UserControl, it crashes at "InitializeComponent()" (of the Child Element) with the exception:
"A first chance exception of type 'System.Configuration.ConfigurationErrorsException' occurred in System.Configuration.dll. Additional information: This element is not currently associated with any context"
I found out why it happens, but I don't know how to solve the problem. If I leave out this code:
public static void EnsureApplicationResources()
{
if (Application.Current == null)
{
// create the Application object
new Application();
string assemblyName = System.IO.Path.GetFileNameWithoutExtension(
Assembly.GetExecutingAssembly().ManifestModule.Name);
// merge in your application resources
Application.Current.Resources.MergedDictionaries.Add(
Application.LoadComponent(new Uri("/KolonistenClient;component/KolonistenResourceDictionary.xaml", UriKind.RelativeOrAbsolute))
as ResourceDictionary);
}
}
then everything is fine. I need that though, because of the fact that my ResourceDictionary (and thus also my defined styles and templates) is otherwise not available throughout the WPF Window and Controls. This I found out about here
Is there any way to combine the best of both worlds? Keeping my ResourceDictionary, while preventing the application from crashing?
