You can do this by trapping the WM_NCRBUTTONDOWN notification that Windows sends when the user right-clicks the title bar. The control class does not have an event for it, you'll need to override WndProc(). Here's an example form, you'll need to add a ContextMenuStrip:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
    }

    protected void OnTitlebarClick(Point pos) {
        contextMenuStrip1.Show(pos);
    }

    protected override void WndProc(ref Message m) {
        const int WM_NCRBUTTONDOWN = 0xa4;
        if (m.Msg == WM_NCRBUTTONDOWN) { 
            var pos = new Point(m.LParam.ToInt32());
            OnTitlebarClick(pos);
            return;
        }                                           
        base.WndProc(ref m);
    }
}
