What are you using? This works for me in VS2005

C# DLL
-----------------------
namespace ClassLibrary1
{
    public class Const
    {
        public Const()
        {
        }

        public String Version
        { get { return "Const" ;}}
    }
}

-------------------
VB.NET
-------------------
Imports ClassLibrary1

Public Class Form1
    Dim Test As ClassLibrary1.Const = New ClassLibrary1.Const

    Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        MsgBox(Test.Version)
    End Sub
End Class
