Answer 1

Windows phone default having Ui like Metro type.There is no property to set corner radius for Windows phone buttons. But our requirement is to create a button with curve edges.so that we can do like this by overriding control template of button.

 <Button  HorizontalAlignment="Left" Margin="47,636,0,0" Name="SignUpButton" 
     VerticalAlignment="Top"   FontSize="18" Background="#6BA92A" Click="SignUpButton_Click">
    <Button.Template>
        <ControlTemplate>
            <Border BorderBrush="#6BA92A" Background="#6BA92A" CornerRadius="20,20,20,20" BorderThickness="2">
                <Button   Content="Sign up "
                          Background="{TemplateBinding Background}"
                          Height="65"
                          Width="348"
                          FontSize="{TemplateBinding FontSize}"
                          BorderBrush="#6BA92A">
