I am following the example for Jobs to create a self installing sitefinity module. I also have been translating it all into VB. 

The error I am getting when debugging is the following. 
"Unable to merge MetadataSource provided by 'DynamicModule.ns.Wrapped_OpenAccessRotatorDataProvider_dc436eb27ef04804b337c0b06d09ca04': There is no field with name 'supportsContentLifecycle' backing 'SupportsContentLifecycle' property in type 'Rotator.Model.RotatorApplication'. You need to either change the Field Naming rules of the mapping configuration object or call HasFieldName(string) with the name of the backing field."

The error occurs at the following code in my RotatorManager.vb.

Public Shared Function GetManager(providerName As String) As RotatorManager
       Return ManagerBase(Of RotatorDataProviderBase).GetManager(Of RotatorManager)(providerName)
   End Function

The part that is referenced is in this class.
Imports Telerik.OpenAccess
Imports Telerik.Sitefinity
Imports Telerik.Sitefinity.GenericContent.Model
Imports System.Runtime.Serialization
 
Namespace Model
 
    <DataContract([Namespace]:="Rotator", Name:="RotatorApplication")> _
    <ManagerType("Rotator.RotatorManager, Rotator")> _
    <Persistent(IdentityField:="contentId")> _
    Public Class RotatorApplication
        Inherits Content
        Public Overrides ReadOnly Property SupportsContentLifecycle() As Boolean
            Get
                Return False
            End Get
        End Property
 
        Private _imagePath As String
        Private _slideDescription As String
        Private _text As String
        Private _slideName As String
 
        <DataMember()> _
        <FieldAlias("imagePath")> _
        Public Property ImagePath() As String
            Get
                Return Me._imagePath
            End Get
            Set(value As String)
                Me._imagePath = value
            End Set
        End Property
 
        <DataMember()> _
        <FieldAlias("slideDescription")> _
        Public Property SlideDescription() As String
            Get
                Return Me._slideDescription
            End Get
            Set(value As String)
                Me._slideDescription = value
            End Set
        End Property
 
        <DataMember()> _
        <FieldAlias("text")> _
        Public Property Text() As String
            Get
                Return Me._text
            End Get
            Set(value As String)
                Me._text = value
            End Set
        End Property
 
        <DataMember()> _
        <FieldAlias("slideName")> _
        Public Property SlideName() As String
            Get
                Return Me._slideName
            End Get
            Set(value As String)
                Me._slideName = value
            End Set
        End Property
 
 
    End Class
End Namespace

Any help would be appreciated. 

Thanks,
Lonnie
