Already a bit old, but here the solution in pure xaml:

<TextBlock VerticalAlignment="Center"
           Text="{Binding ErrorMsg, NotifyOnTargetUpdated=True}">
    <TextBlock.Triggers>
        <EventTrigger RoutedEvent="Binding.TargetUpdated">
            <BeginStoryboard>
                <Storyboard>
                    <DoubleAnimation BeginTime="0:0:0"
                                     Duration="0:0:1"
                                     From="0.0"
                                     Storyboard.TargetProperty="Opacity"
                                     To="1.0" />
                </Storyboard>
            </BeginStoryboard>
        </EventTrigger>
    </TextBlock.Triggers>
</TextBlock>

did you set the NotifyOnTargetUpdated property to true

<TextBlock Text="{Binding Path=YourProperty, NotifyOnTargetUpdated=True}" TargetUpdated="OnTargetUpdated"/>
