Just in case someone lands here searching for the error message, I was getting it simply because I was mistakenly using x:Static instead of StaticResource to access a locally declared resource.

Hope this helps someone down the road.

My head hurts from banging it against my keyboard after reading your answer. Made my day :-) – alzaimar Mar 01 '21 at 13:51

In my case it was a missing `TargetType` prop on a style declaration... – rnort Jul 16 '21 at 15:27

i had solved the problem by this code

<chartingToolkit:LineSeries.DataPointStyle>
    <Style TargetType="chartingToolkit:DataPoint">
        <Setter Property="Background" Value="#0077CC" />
        <Setter Property="BorderBrush" Value="White"/>
        <Setter Property="BorderThickness" Value="2"/>
        <Setter Property="IsTabStop" Value="False"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="chartingToolkit:LineDataPoint">
                    <Grid x:Name="Root" Opacity="1">
                        <ToolTipService.ToolTip>
                            <StackPanel Margin="2,2,2,2">
                                <ContentControl Content="{TemplateBinding IndependentValue}" ContentStringFormat="Date : {0}"/>
                                <ContentControl Content="{TemplateBinding DependentValue}" ContentStringFormat="Count : {0:###,###,###}"/>
                            </StackPanel>
                        </ToolTipService.ToolTip>
                        <Ellipse StrokeThickness="{TemplateBinding BorderThickness}" Stroke="{TemplateBinding BorderBrush}" Fill="{TemplateBinding Background}"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</chartingToolkit:LineSeries.DataPointStyle>

If anyone doesn't understand this solution, it is because the question author tried to use a `TemplateBinding` outside of a `ControlTemplate`, where this special kind of binding is supposed to be used. This solution was therefore, to use it within a `ControlTemplate`. — Sheridan, Sep 16 '21 at 09:47

Just incase someone needs glasses, like me..

Before (failing XAML)

<Setter Property="Command" Value="{x:Static local:Map:ZoomCommand}" />

After (fixed XAML)

<Setter Property="Command" Value="{x:Static local:Map.ZoomCommand}" />

I just needed to change the colon to a dot.
