How to provide the outer glow effect to border?

<Grid Width="200" Height="200">     <Grid.Background>         <RadialGradientBrush Center="0.5,0.5" GradientOrigin="0.5,0.5" RadiusX="0.8" RadiusY="0.8">             <RadialGradientBrush.GradientStops>                 <GradientStop Offset="0" Color="#FF123B5F" />                 <GradientStop Offset="1" Color="#FF001F31" />             </RadialGradientBrush.GradientStops>         </RadialGradientBrush>     </Grid.Background>     <Border Width="180" Height="180" Margin="10" Background="Transparent"             BorderBrush="White" BorderThickness="1">         <Border.BitmapEffect>             <OuterGlowBitmapEffect GlowColor="White" GlowSize="3" Opacity="1" />         </Border.BitmapEffect>     </Border> </Grid>

BitmapEffects are no longer supported in .NET 4.0.

From MSDN

Important In the .NET Framework 4 or later, the BitmapEffect class is obsolete. If you try to use the BitmapEffect class, you will get an obsolete exception. The non-obsolete alternative to the BitmapEffect class is the Effect class. In most situations, the Effect class is significantly faster.

It isn't the same thing but you can try with a DropShadowEffect with ShadowDepth close to 0 instead.

Example

<Border Width="180" Height="180" Margin="10" Background="Transparent"         BorderBrush="White" BorderThickness="2" Opacity="1.0">     <Border.Effect>         <DropShadowEffect ShadowDepth="0"                           Color="White"                           Opacity="1"                           BlurRadius="5"/>     </Border.Effect> </Border> 

Comparison between the BitmapEffects you had and DropShadowEffect above. DropShadowEffect to the right.
