DependencyProperty causes crash

[vb2ae]

I am trying to set or get a value of a dependency property in code and my app exists.

For example this works

public sealed partial class HomeView : UserControl
{
    public HomeView()
    {
        this.InitializeComponent();
        var obj = this as DependencyObject;
        obj.SetValue(IsGeneratedProperty, false);
    }

    public static readonly DependencyProperty IsGeneratedProperty =
DependencyPropertyHelper.RegisterAttached(
    "IsGenerated",
    typeof(bool),
    typeof(DependencyObject));
}

if I try to set the dependency property from a dependency property in a dll my app crashes

    public HomeView()
    {
        this.InitializeComponent();
        var obj = this as DependencyObject;
        obj.SetValue(View.IsGeneratedProperty, false);
    }

I see this in the output window

The thread 0x3878 has exited with code 0 (0x0).
The program '[26584] Caliburn.Micro.WinAppSdk.Test.exe' has exited with code 3221226107 (0xc000027b).

Any suggestions on how to fix this?

Is the DependencyObject actually a View? Most references online to this error make it sound like a type resolution error.
