You can use the DebuggerDisplay Attribut like in the sample shown below.

Sample C#

class Program
    {
        static void Main(string[] args)
        {
            var myPlayer = new Player
            {
                Firstname = "John", 
                Lastname = "Doe", 
                CreationDate = DateTime.Now, 
                Points = 9999
            };
            Console.WriteLine("Firstname={0}, Lastname={1}, Points={2}, CreationDate={3}", myPlayer.Firstname, myPlayer.Lastname, myPlayer.Points, myPlayer.CreationDate);
        }

        [DebuggerDisplay("Firstname={Firstname}, Lastname={Lastname}, Points={Points}, CreationDate={CreationDate}")]
        public class Player
        {
            public string Firstname { get; set; }
            public string Lastname { get; set; }
            public long Points { get; set; }
            public DateTime CreationDate { get; set; }
        }

Sample VB.NET

Sub Main(args As String())
        Dim myPlayer = New Player() With { _
            .Firstname = "John", _
            .Lastname = "Doe", _
            .CreationDate = DateTime.Now, _

        }
        Console.WriteLine("Firstname={0}, Lastname={1}, Points={2}, CreationDate={3}", myPlayer.Firstname, myPlayer.Lastname, myPlayer.Points, myPlayer.CreationDate)
    End Sub

    <DebuggerDisplay("Firstname={Firstname}, Lastname={Lastname}, Points={Points}, CreationDate={CreationDate}")> _
    Public Class Player
        Public Property Firstname() As String
            Get
                Return m_Firstname
            End Get
            Set(value As String)
                m_Firstname = Value
            End Set
        End Property
        Private m_Firstname As String
        Public Property Lastname() As String
            Get
                Return m_Lastname
            End Get
            Set(value As String)
                m_Lastname = Value
            End Set
        End Property
        Private m_Lastname As String
        Public Property Points() As Long
            Get
                Return m_Points
            End Get
            Set(value As Long)
                m_Points = Value
            End Set
        End Property
        Private m_Points As Long
        Public Property CreationDate() As DateTime
            Get
                Return m_CreationDate
            End Get
            Set(value As DateTime)
