Here's custom style:
<Style TargetType="{x:Type Button}">
<Setter Property="Focusable" Value="false" />
<Setter Property="Background" Value="{StaticResource AppBackBrush}"/>
<Setter Property="Foreground" Value="{StaticResource AppBrush}"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="Button">
<Border BorderBrush="{StaticResource AppBrush}"
Name="content"
BorderThickness="1"
CornerRadius="3"
Background="{StaticResource AppBackBrush}"
>
<Grid Background="Transparent">
<Label Content="{TemplateBinding Content}"
HorizontalContentAlignment="Center"
VerticalContentAlignment="Center"
Grid.Row="0" Grid.Column="0"
Background="Transparent"
Style="{x:Null}"
Foreground="{TemplateBinding Foreground}"
Padding="{TemplateBinding Padding}"/>
</Grid>
<Border.RenderTransform>
<!-- push the content a bit to the left and the top -->
<TranslateTransform x:Name="translation"
X="-1" Y="-1"/>
</Border.RenderTransform>
</Border>
<ControlTemplate.Triggers>

I save this ResourceDictionary that contains this style to string like this:
XamlWriter.Save(s);
where s is ResourceDictionary. The problem is that when I get expected string, it looks so:
<Style TargetType=\"Button\" x:Key=\"{x:Type Button}\">
<Style.Resources>
<ResourceDictionary />
</Style.Resources>
<Setter Property=\"UIElement.Focusable\">
<Setter.Value>
<s:Boolean>False</s:Boolean>
</Setter.Value>
</Setter>
<Setter Property=\"Panel.Background\">
<Setter.Value>
<SolidColorBrush>#FFF1F2F4</SolidColorBrush>
</Setter.Value>
</Setter>
<Setter Property=\"TextElement.Foreground\">
<Setter.Value>
<SolidColorBrush>#FF13776A</SolidColorBrush>
</Setter.Value>
</Setter>
<Setter Property=\"Control.Template\">
<Setter.Value>
<ControlTemplate TargetType=\"Button\">
<Border BorderThickness=\"1,1,1,1\" CornerRadius=\"3,3,3,3\" BorderBrush=\"#FF13776A\" Background=\"#FFF1F2F4\" Name=\"content\">
<Border.RenderTransform>
<TranslateTransform X=\"-1\" Y=\"-1\" />
</Border.RenderTransform>
<Grid>

Please take a look at TranslateTransform in Border.RenderTransform. In the ResourceDictionary it has x:Name="translation", but the name is missing in the output string.
Where was I mistaken or is this a bug? Thanks in advance.
According to this MSDN blog post, "some markup extensions, such as {x:Static}, are resolved at load-time by XamlReader and the markup extension itself is discarded, so there is no means for XamlWriter to re-produce it." It looks like x:Name is one of those markup extensions that is lost.
It looks like you are trying to create two styles - an original and an extended one - that both implicitly target button (presumably in different scopes). If that is the case, you can create a base style in a resource both styles above can reference, then use Style's BasedOn property to keep from duplicating the template.
