Hello,
create a new Telerik WPF application and

Create a class MyCheckBoxBox.cs, with:
using System;
using System.Windows.Controls;
using Telerik.Windows.Controls;
 
namespace RadControlsWpfApp2
{
  class MyCheckBox : CheckBox
  {
    public MyCheckBox() {
      StyleManager.SetTheme(this, StyleManager.ApplicationTheme);
    }
  }
}

Replace MainWindow.cs with:
using System;
using System.Windows;
using Telerik.Windows.Controls;
 
namespace RadControlsWpfApp2
{
  /// <summary>
  /// Interaction logic for MainWindow.xaml
  /// </summary>
  public partial class MainWindow : Window
  {
    public MainWindow()
    {
      StyleManager.ApplicationTheme = new SummerTheme();
      InitializeComponent();
      StyleManager.SetTheme(CheckBox3, StyleManager.ApplicationTheme);
    }
  }
}

Replace MainWindow.xaml.cs with:
<Window
  x:Class="RadControlsWpfApp2.MainWindow"
  xmlns:my="clr-namespace:RadControlsWpfApp2"
  Title="MainWindow" Height="350" Width="525">
  <Grid HorizontalAlignment="Center"
        Margin="5"
        VerticalAlignment="Center">
    <Grid.RowDefinitions>
      <RowDefinition Height="Auto" />
      <RowDefinition Height="Auto" />
      <RowDefinition Height="Auto" />
    </Grid.RowDefinitions>
     
    <CheckBox Content="With theme set in XAML"
              Margin="5"
              telerik:StyleManager.Theme="Summer" />
 
    <my:MyCheckBox Content="With theme set in code-behind (control)"
                   Margin="5"
                   Grid.Row="1" />
 
    <CheckBox Name="CheckBox3"
              Content="With theme set in code-behind (main page)"
              Margin="5"
              Grid.Row="2" />
 
  </Grid>
</Window>

Now run the application.

The second check box is not displayed in the window!
The same code (setting the theme in the control, just after the call to the inherited constructor) works well in Silverlight, but now in WPF.

Do you have a solution to make it work correctly in WPF, while having the same code for Silverlight?
