The approach I just used was to simply add CornerRadius to the "RootGrid" grid in the Button template.
```
<Style TargetType="Button" x:Key="RoundedButton">
    ...
    <Grid x:Name="RootGrid" CornerRadius="10" Background="{TemplateBinding Background}"> 
    ...
</Style>
```

There are few ways to achieve this, one by using a style can look like this - remove BorderBrush from ContentPresenter and add an Ellipse with that brush. Sample in XAML:

<Page.Resources>
    <Style x:Key="CircleButtonStyle" TargetType="Button">
        <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundBaseLowBrush}"/>
        <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
        <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}"/>
        <Setter Property="BorderThickness" Value="{ThemeResource ButtonBorderThemeThickness}"/>
        <Setter Property="Padding" Value="8,4,8,4"/>
        <Setter Property="HorizontalAlignment" Value="Left"/>
        <Setter Property="VerticalAlignment" Value="Center"/>
        <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}"/>
        <Setter Property="FontWeight" Value="Normal"/>
        <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}"/>
        <Setter Property="UseSystemFocusVisuals" Value="True"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="Button">
                    <Grid x:Name="RootGrid">
                       <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal">
                                    <Storyboard>
                                        <PointerUpThemeAnimation Storyboard.TargetName="RootGrid"/>
                                    </Storyboard>
                                </VisualState>

                                        </ObjectAnimationUsingKeyFrames>
                                        <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Foreground" Storyboard.TargetName="ContentPresenter">

                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <ContentPresenter x:Name="ContentPresenter" VerticalAlignment="Center" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" Content="{TemplateBinding Content}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        <Ellipse x:Name="BorderCircle" Stroke="{TemplateBinding BorderBrush}" StrokeThickness="2"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Page.Resources>

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Button Content="text" Width="50" Height="50" BorderBrush="Blue" Style="{StaticResource CircleButtonStyle}"/>
</Grid>

I've also made some changes in VisualStates so that it doesn't look weird once clicked/disabled.

Are you looking for something like this?

<StackPanel>
    <Button Background="Transparent">
        <StackPanel>
            <Border CornerRadius="10" 
                    Background="Transparent" 
                    BorderBrush="White" 
                    BorderThickness="3">
                <TextBlock Text="MyButton" 
                           Margin="10" 
                           Foreground="White"/>
            </Border>
        </StackPanel>
    </Button>
</StackPanel>

With version 1809 and later (even if you're targeting an earlier version like me below) you can just do this for an example of a round button:
```
<Button
    Content="Stuff"
    Windows10version1809:CornerRadius="90,90,90,90"
    Height="64"
    Width="64">
</Button>
```
and voila!

Make sure to add this at the top of your XAML with the other xmlns stuff.
```
xmlns:Windows10version1809="http://schemas.microsoft.com/winfx/2006/xaml/presentation?IsApiContractPresent(Windows.Foundation.UniversalApiContract, 7)"
```

I don't know if the OP is still interested in rounded corner buttons, but for sake of completeness I think it may be helpful for other users to point out, as the user peterincumbria said, that for the lastest build of Windows 10 (1809) there is a new property in the class Control: CornerRadius. So now the following code is enough:
```
<Button Content="DEMO"
        Background="Transparent"                    
        BorderThickness="1.0"
        BorderBrush="White"
        CornerRadius="10"
        HorizontalAlignment="Center"
        VerticalAlignment="Center"/>
```
Put this inside a Grid and we have a rounded corner button in the middle of the Page.
