Icon Badge on Fluent Ribbon button control in WPF

I am new to WPF and trying to show badge at the top right corner of button image. Button is being displayed on Fluent ribbon. I have come across nir's answer here which looks good but i don't know how to apply this to button control.

iPhone like red badge notification in a WPF project?

Here is the button control on which i am trying to apply badge.

  <Fluent:RibbonGroupBox Fluent:KeyTip.Keys="C" Header="">
                        <Fluent:Button Fluent:KeyTip.Keys="LC" Header=" Transactions" Name="btnTransactions" MinHeight="67" Icon="Images/transferbig.gif" LargeIcon="Images/transfer.gif" FontWeight="Normal"></Fluent:Button>
                    </Fluent:RibbonGroupBox>

Please do advise if there is any other way of doing it which is compatible with windows 7 , 8 and 10.

I have come across this https://mahapps.com/controls/badged-control.html which i believe open for anyone to use it but not sure if it works with windows 8.

If I understand your question correctly you could put the Label on top of the Button and adjust its position using the Margin property, e.g.:

<Fluent:RibbonGroupBox Fluent:KeyTip.Keys="C" Header="" ClipToBounds="False" Margin="10">
    <Grid>
        <Fluent:Button Fluent:KeyTip.Keys="LC" Header=" Transactions" Name="btnTransactions" MinHeight="67" FontWeight="Normal" />
        <Label Style="{StaticResource CircularLabel}" HorizontalAlignment="Right" VerticalAlignment="Top" Margin="0,-8,-8,0">2000</Label>
    </Grid>
</Fluent:RibbonGroupBox>

This should give you a badge at the top-right corner of the Button.
