You can use a dictionary in the current project or another project to UserControl,here is the structure of my test demos for you to refer to:

The code for DictionaryB.xaml which included in namespace WpfControlLibrary2:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
                    xmlns:local="clr-namespace:WpfControlLibrary2">  
    <Style x:Key="MyTxtStyleB" TargetType="TextBlock">  
        <Setter Property="FontSize" Value="20"></Setter>  
        <Setter Property="Foreground" Value="Yellow"></Setter>  
        <Setter Property="Background" Value="LightPink"></Setter>  
    </Style>  
</ResourceDictionary>  

The code for DictionaryA.xaml which included in namespace WpfControlLibrary:

The code for UserControl1.xaml which included in namespace WpfControlLibrary:

Use it the MainWindow.xaml which included in namespace DictionaryUse:

<Grid>  
        <u:UserControl1></u:UserControl1>  
    </Grid>
