wpf throw Could not load file or assembly 'System.Windows.Forms exception on starting if published with --self-contained

### Description

When I run the wpf application it throw
Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'. The system cannot find the file specified.
if any third party need System.Windows.Forms when I publish the application using --self-contained and works fine if --self-contained=false

### Reproduction Steps

Create a new wpf project and references it for example Microsoft.AppCenter which requires System.Windows.Forms

configure the AppCenter on startup

```
public partial class App : Application
{
public App()
{
Application.Current.DispatcherUnhandledException += Current_DispatcherUnhandledException;
}

private void Current_DispatcherUnhandledException(object sender, System.Windows.Threading.DispatcherUnhandledExceptionEventArgs e)
{
MessageBox.Show(e.Exception.Message);
}

protected override void OnStartup(StartupEventArgs e)
{
base.OnStartup(e);
SetAppCenter();
}
private void SetAppCenter()
{
Microsoft.AppCenter.AppCenter.Start("null",
typeof(Microsoft.AppCenter.Analytics.Analytics), typeof(Crashes));

}

}

```

### Expected behavior

To run normally like self-contained=false publishing
