Vista - Tooltip Template Question

I want to create a Styleto modify the look of the Tooltip in WPF. I found
lots of help on how to do this, but I cannot determine how to set the
Tooltip to this style in XAML, since the Tooltip is an attribute of a
control.

You can simply define your style's TargetType as {x:Type ToolTip}, like
this:

<Style TargetType="{x:Type ToolTip}">

or:

<Style x:Key="{x:Type ToolTip}" TargetType="ToolTip">

Then when you include that style definition as a resource on the window/page
it will apply the style to the Tooltips of all controls automatically.
