                                    <Storyboard>

                        <Border x:Name="ButtonBackground" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" CornerRadius="0" Margin="{StaticResource PhoneTouchTargetOverhang}">
                            <ContentControl x:Name="ContentContainer" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" Padding="{TemplateBinding Padding}" VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ResourceDictionary>

We generally do it in this way programatically in .cs file

button.Style = (Style)App.Current.Resources["MainScreenButtonStyle"];

But how can we access in Phone class library project ?

Answer 1

actually it's quite simple just include ResourceDictionary.xaml file in your class library project, and you have samething like:

 public Button CreateButton() 
        {
            Button b = new Button();
            Application.Current.Resources.Source = new Uri("/ResourceDictionary.xaml", UriKind.Relative);
            b.Style = (Style)Application.Current.Resources["MainScreenButtonStyle"];
            return b;
        }

Answer 2

You have to add your resources xaml to App.xaml to automatically detect it:

<Application.Resources>
    <ResourceDictionary x:Key="myDict">
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="ResourceDictionary.xaml"/>
        </ResourceDictionary.MergedDictionaries>
    </ResourceDictionary>
</Application.Resources>
