You are creating a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
You create a window by using XAML code. You add a button to the window.
You need to ensure that the font weight of the button changes to bold when either of the following events occur:
* The mouse pointer is moved over the button.
* The button is focused.
