Почему мой код показывает предупреждающее сообщение в ide «Доступ к общему члену через экземпляр; уточняющее выражение не будет оцениваться»

I create class

'MyLib.aspx
Namespace MyLib
  Public Class Base

    Public Shared _XPage As Page
    Public Shared _Func  As FuncClass

    Public Shared Property XPage() As Page
      Get
          Return _XPage
      End Get
      Protected Set(Val as Page)
          _Page = Val
      End Set
    End Property 

    Public Sub New(ByVal Page As Page)
      XPage = Page
    End Sub
  End Class

  Public Class FuncClass : Inherits Base

    Public Sub New()
        MyBase.New(_XPage)
    End Sub

    Public Function Test() As String
        Return "Test"
    End Function
  End Class
End Namespace

I try it...

'ASPX_Page.aspx
Import MyLib

Partial Class ASPX_Page

  Private ReadOnly LibX As Base = New Base(Me)

  Protected Sub Button1_Clcik(sender As Object, e As EventArgs)
  Handles Button1.Clcik

    'Access of shared member through an instance; 
    'qualifying expression will not be evaluated
     LibX._Func.Test()

  End Sub
End Class

IDE show Warning message "Access of shared member through an instance; qualifying expression will not > be evaluated", but still working fine

why it show warning message , How can I fix it?
