system.windows.resourcedictionary. source threw an exception wpf c#

In general this issue is caused when a referenced resource cannot be found.

<Application x:Class="AppName.App"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             StartupUri="MainWindow.xaml">
    <Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="/PresentationFramework.Aero;component/themes/Aero.NormalColor.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>
</Application>

In my specific circumstance, as the xaml above details, this issue was caused by a reference to PresentationFramework.Aero DLL that was not contained in the output bin folder of the compiled project. Under references, setting Copy Local to true did the trick for me.
