I've got a style declared where, within the Template setter, I try to drop
in a previously-declared resource declared like so:
<Polyline x:Key="UpArrowGlyph" Points="0,0 0.5,0.3 1,0" Stroke="#FF5B6473"
StrokeThickness="0.2" RenderTransformOrigin="0.5,0.5">

<Polyline.RenderTransform>

<RotateTransform Angle="180"/>

</Polyline.RenderTransform>

</Polyline>





However, I can't seem to get the syntax for dropping it into a style. I use
them in my UI itself, and it works just fine, but if I construct my template
in this way:

<Viewbox Stretch="Fill">

<StaticResource ResourceKey="UpArrowGlyph" />

</Viewbox>

It says I can't use non-frameworkelements in my style. I know I'm missing
some basic piece of syntax, but I've been stumped on this one for several
days (including getting sidetracked on a 360 ).

I don't think it has anything to do with the resource reference, it's
because Polyline is not a subclass of FrameworkElement. The root element in
the template must be a framework element, if you don't have a useful
framework element just use a Border with zero-sized border.

D'oh! It was pointed out to me that PolyLine is a Shape and thus a
FrameworkElement.

What's the complete xaml you're using?

This is the style:
<Style x:Key="{x:Type ScrollBar}"
TargetType="{x:Type ScrollBar}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type ScrollBar}">
<Grid Background="{TemplateBinding Background}">
<RowDefinition MaxHeight="{DynamicResource {x:Static
SystemParameters.VerticalScrollBarButtonHeightKey}}" />
<RowDefinition Height="1E-05*" />
<RowDefinition MaxHeight="{DynamicResource {x:Static
SystemParameters.VerticalScrollBarButtonHeightKey}}" />
<RepeatButton Command="ScrollBar.LineUpCommand"
Height="{DynamicResource {x:Static
SystemParameters.VerticalScrollBarButtonHeightKey}}"
MinWidth="{DynamicResource {x:Static
SystemParameters.VerticalScrollBarWidthKey}}">
<Viewbox Stretch="Fill">
<StaticResource ResourceKey="UpArrowGlyph"
/>
</Viewbox>
</RepeatButton>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>

And teh resource is here:
<Polyline x:Key="UpArrowGlyph"
Points="0,0 0.5,0.3 1,0"
Stroke="#FF5B6473"
StrokeThickness="0.2"
RenderTransformOrigin="0.5,0.5">
<Polyline.RenderTransform>
<RotateTransform Angle="180"/>
</Polyline.RenderTransform>
</Polyline>
