You probably need to change the Padding and BorderThickness properties of the button. As code below :

    <Button Grid.Column="0" Height="39" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Padding="0" BorderThickness="0">
        <Image Source="Assets/microsoft.png" Stretch="UniformToFill"/>
    </Button>
