Answer 1

When I tried the above code, the error I got was:

Error 1 'ResourceDictionary' root element requires a x:Class attribute to support event handlers in the XAML file. Either remove the event handler for the Click event, or add a x:Class attribute to the root element. Line 10 Position 35

This is how I fixed it:

1) Added x:Class attribute to the ResourceDictionary:

x:Class="WpfApplication4.Dictionary1"

2) Added a C# class file to the project, Code below:

public partial class Dictionary1 : ResourceDictionary
{
    public Dictionary1()
    {
        InitializeComponent();
    }

    void OnMenuItemClick(object sender, RoutedEventArgs e)
    {

    }
}

And then, the project built fine.
