I have a DLL program and am trying to update it with Descriptions but can't get them to work

Question

I have a DLL program that I wrote a few years back and am trying to update it with Descriptions but can't get them to work.

Here is my code:

<Browsable(True)>
<EditorBrowsable(EditorBrowsableState.Always)>
<Description("Get email Information")>
<DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)>
Public Function getemail(ByVal source As String) As String()

and this is what I am trying to do - the part in the circle:

Try inserting this before

    /// <summary>
    /// Get email Information
    /// </summary>
