                    <ControlTemplate TargetType="Button">
                        <Grid>
                            <Ellipse Stroke="#5ECF5E"
                         StrokeThickness="2">
                                <Ellipse.Fill>
                                    <RadialGradientBrush GradientOrigin="0.496,1.052">
                                        <RadialGradientBrush.RelativeTransform>
                                            <TransformGroup>
                                                <ScaleTransform CenterX="0.5" CenterY="0.5" ScaleX="1.5" ScaleY="1.5"/>
                                                <TranslateTransform X="0.02" Y="0.2"/>
                                            </TransformGroup>
                                        </RadialGradientBrush.RelativeTransform>
                                        <GradientStop Offset="1" Color="#5ECF5E"/>
                                        <GradientStop Offset="0.2" Color="#FFFFFFFF"/>
                                    </RadialGradientBrush>
                                </Ellipse.Fill>
                            </Ellipse>
                            <ContentPresenter HorizontalAlignment="Center"
                                  VerticalAlignment="Center"/>
                        </Grid>
                    </ControlTemplate>
                </Button.Template>
            </Button>

another one way to create the round button.

<Button  Width="100" Height="100" Content="Abcd">
        <Button.Template>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid>
                <Ellipse Fill="Red"/>
                    <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Grid>
            </ControlTemplate>
        </Button.Template>
    </Button>

this code create an rectangle button with color and Radial Gradient color and also we can able to apply the Transform using opacity.

    Height="154" Width="177">
    <Grid>
        
        <Rectangle Name="rectangle1" Stroke="Black" RadiusX="10" RadiusY="10" >
        </Rectangle>
 
        <Button Name="rectangle2" Foreground="Black" Margin="3,3,3,3" >
            <Button.Background >
                <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
                    <GradientStop Color="Green" Offset="0.0" />
                    <GradientStop Color="White" Offset="0.9" />
                </LinearGradientBrush>
            </Button.Background>
        </Button>
    </Grid>
</UserControl>
