WPF UserControl that does not derive from UserControl directly

I Would like to create several WPF UserControl classes with some common functionality. For this reason I would like to derive the classes from a new base class that in turns derives from UserControl.

My problem is that my C# class is defined partial, and the automatically generated other part derives from UserControl and not from my new base class. Can I make Visual Studio derive the partial class from my base class instead of UserControl?

Sure - create a class that serves as the base call for your user controls:

public class BaseUserControl : UserControl
{
    //TODO: Add your common functionality
}

Next, create a user control, and change the root declaration to reference your base class:

<controls:BaseUserControl x:Class="WpfApplication2.UserControl1"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             xmlns:controls="clr-namespace:WpfApplication2"
             mc:Ignorable="d" 
             d:DesignHeight="300" d:DesignWidth="300">
    <Grid>

    </Grid>
</controls:BaseUserControl>

And change the partial class to match as well:

public partial class UserControl1 : BaseUserControl
{
    public UserControl1()
    {
        InitializeComponent();
    }
}
