title: Can't access my class from code-behind. Class is App_Code folder
body: <p>I have a very simple class that is located within my App_Code folder in my VS2008 web application project. I am trying to instantiate an instance of this class from my code-behind file. Intellisense does not seem to be seeing my class and I am not sure why. I am using VB.NET which I am admittedly not that familiar with as compared to C#. Perhaps I am missing something. I would bet it has something to do with something I am missing in VB.NET.</p>
  
  <p>Here is my simple class (for testing):</p>
  
  <pre><code>Public Class mySimpleClass
  
     'Private member variables whose data is obtained from user input
      Private mUserID as String
  
     'Class Properties
      Public Property UserID() as Integer
         Get
            Return mUserID
         End Get
  
         Set(ByVal Value as Integer)
            mUserID = Value
         End Set
      End Property
  
      'Class Methods
      Public Function DisplayUserID() as String
         Return this.UserID
      End Function
  
  End Class
  </code></pre>
  
  <p>Here is how I try an instantiate it from the codebehind ...</p>
  
  <pre><code>Partial Public Class _Default
      Inherits System.Web.UI.Page
  
      Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
          Dim obj As New mySimpleClass()
      End Sub
  
  End Class
  </code></pre>
