If you're using WinForms and you want to execute something on the UI thread, you need to call either Invoke or BeginInvoke on some control (be it a Button or a Form or whatever) that was created on that thread. You'll need a reference to it in order to do this.

For example, with your code and assuming that you have a reference to a form called form:

private uint lgLcdOnConfigureCB(int connection, System.IntPtr pContext)
{
    form.Invoke(new MethodInvoker(() => OnConfigure(EventArgs.Empty)));
    return 0U;
}
