OK - I'll look into this further. It turns out the .NET 3.5 DOES allow this:
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
Button btnCopy;
Button btn = new Button();
this.Controls.Add(btn);
btnCopy = (Button)this.Controls[0];
bool yes = (btn == btnCopy);
}
}
}
