How to Include Third-Party Control Style in a Merged Dictionary

Question

I am getting an error trying to create a style for a third-party control in a Merged Dictionary. Here is my Applicatiojn.xaml:

<Application  
    x:Class="Application"  
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">  
    <Application.Resources>  
        <ResourceDictionary>  
            <ResourceDictionary.MergedDictionaries>  
                <ResourceDictionary Source="Models/BaseResources.xaml"/>  
            </ResourceDictionary.MergedDictionaries>  
        </ResourceDictionary>  
    </Application.Resources>  
</Application>  

and here is the relevant part of the Merged Dictionary:

<ResourceDictionary  
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  
    xmlns:xctk="http://schemas.xceed.com/wpf/xaml/toolkit">  
    <Style  
        x:Key="DateTimePickerBase"  
        TargetType="{x:Type xctk:DateTimePicker}">  
        <Setters .... >  
 <....>  
</ResourceDictionary>  

I get this error:

Failed to create a 'Type' from the text 'xctk:DateTimePicker'

The Merged Dictionary, BaseResources.xaml, has Build Action = Resource My searches have not yielded any useful results. What am I missing?

Hi, @RogerSchlueter-7899 . Welcome to Microsoft Q&A.

You could set Build Action to Page and now it will work.

Hope my solution could help you.
