Inside a Silverlight library project I have a public event, which is not visible for other classes. How can I make the event visible?

When I try the following code, I can not locate the event in the "ReceivingClass".

.dll - file:

Public Class MyClass
    Public Event MyEvent(ByVal sender As Object, ByVal e As EventArgs)

    Public Sub OnStart()
        RaiseEvent MyEvent(Me, new EventArgs)
    End Sub

End Class

Silverlight app:

Imports MyClass
Public Class ReceivingClass

    Public Sub New()
        Dim myClass As new MyClass
        AddHandler myClass.MyEvent, AddressOf Me.EventHandler
    End Sub

    Private Sub EventHandler(ByVal sender As Object, ByVal e As EventArgs)
      'Handle Event
    End Sub

End Class
