how to use an application resource in user control xaml - wpf

Question

I have a app.xml with some resources in it such as:
<Application.Resources>
<con:EnumToVisibilityConverter x:Key="EnumToVisibilityConverter" />
<con:NegateBoolConverter x:Key="NegateBoolConverter" />
<Style TargetType="FrameworkElement" x:Key="BaseStyle">
<Setter Property="HorizontalAlignment" Value="Stretch" />
<Setter Property="VerticalAlignment" Value="Stretch" />
<Setter Property="Margin" Value="3"/>
<Setter Property="Width" Value="120"/>
<Setter Property="Height" Value="25" />
</Style>
<Style TargetType="CheckBox" BasedOn="{StaticResource BaseStyle}">
</Style>
<Style TargetType="DatePicker" BasedOn="{StaticResource BaseStyle}">
</Style>
<Style TargetType="TextBox" BasedOn="{StaticResource BaseStyle}">
</Style>
<Style TargetType="Label" BasedOn="{StaticResource BaseStyle}">
</Style>
<Style TargetType="Button" BasedOn="{StaticResource BaseStyle}">
<Setter Property="Width" Value="75" />
<Setter Property="Height" Value="23" />
<Setter Property="Margin" Value="5,2,2,5" />
<Setter Property="HorizontalAlignment" Value="Left" />
<Setter Property="VerticalAlignment" Value="Top" />
</Style>
</Application.Resources>
I want to use them in my user control xaml as follow:
<UserControl.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="App.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</UserControl.Resources>
Since my user control xaml is in View directory, the above mentione syntax is not accepted by system and complained that it can not find view/app.xaml. How can I add path to the Source so it can find it?

You don't need to do that. Application resources are available all over the app, so all you need to do is either this in xaml:
Style="{StaticResource BaseStyle}"
Or this in C# (inside your control's code):
Style baseStyle = (Style)this.FindResource("BaseStyle");
