WPF: Object doesn't exist in namespace - wpf

Question

I have got an object in App.xaml.cs as you can see here
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.ComponentModel;
using System.Configuration;
using System.Data;
using System.Linq;
using System.Threading.Tasks;
using System.Windows;
namespace Test_Project
{
/// <summary>
/// Interaction logic for App.xaml
/// </summary>
public partial class App : Application
{
protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
//Startup
Window main = new MainWindow();
main.Show();
}
}
/// <summary>
/// Global values for use during application runtime
/// </summary>
public class runtimeObject : INotifyPropertyChanged
{
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string name)
{
if (PropertyChanged != null)
{
PropertyChanged(this, new PropertyChangedEventArgs(name));
}
}
....
I'm trying to create an instance of the object for use for the duration my application is running. I'm creating this instance in the XAML in App.xaml
<Application x:Class="Test_Project.App"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:Test_Project">
<Application.Resources>
<local:runtimeObject x:Key="runtimeVariables" />
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Styles/Generic.xaml"/>
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
</Application>
I'm getting the error saying that my class doesn't exist in the namespace. However the xmlns:local does reference the namespace which contains the object, any ideas ?

Woops, the <local:runtimeObject x:Key="runtimeVariables" /> had to go in the <ResourceDictionary> and then I had to rebuild the solution.
