using System; using System.Drawing; using System.Windows.Forms; namespace BaseControls { public class BaseTextBox : TextBox { public override Font Font { get { return base.Font; } set {base.Font = value; } // new line } public BaseTextBox() { base.Font = new Font("Tahoma",8); } } }My problem is that the code will not compile correctly under Visual C# (Express). The first 'Font' above is underlined and I get the error message "The type or namespace 'Font' could not be found (are you missing a using directive or an assembly reference?)"
