Did you add using statements so the attributes can be seen?
using MicroFour.StrataFrame.UI.Windows.Forms;
using System.ComponentModel;
I think these are the two needed...check the help file for custom properties.
Second, just in case you aren't used to attributes with c#, they use square brackets, not angle brackets:
[Browsable(False),
BusinessFieldDisplayInEditor(),
Description("Full Name"),
DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
