I believe you need to add a key to your ResourceDictionary tag:

<UserControl.Resources>
    <ResourceDictionary x:Key="ucRescDict">
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/PDMC;component/Views/XamlResources/AppFormsStyle.xaml" />
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
    <converters:InvertBooleanToVisibilityConverter x:Key="invertBoolToVisibility" />
</UserControl.Resources>
