WPF Application using a global variable

Answer 1

There are two different things you can do here (among others; these are just the two that come to mind first).

1. You could make the variable static on Home.xaml.cs

   public static string Foo = "";
   

2. You could just pass in the variable to all three forms.

I would go with #2, myself, and if necessary create a separate class that contains the data I need. Then each class would have access to the data.
