something is wrong in vb.net 2005

[MackAA]

Hello everybody,

If anyone could tell me what's wrong in this folloeing code snippet, I'll appreciate.

'1. Create 4 classes (I've removed all internal code since it is useless for the test)



Public Class LockableDataObject

End Class



Public Class Business

Inherits LockableDataObject

End Class



Public Class LockableDataManager(Of CustomType As LockableDataObject)

End Class



Public Class BusinessManager

Inherits LockableDataManager(Of Business)

End Class



Module main

Public Sub main()

'This line works

Dim MyManager As LockableDataManager(Of Business) = New BusinessManager



'This line doesn't
(Is this a bug? or is this wanted?)

Dim MyManager2 As LockableDataManager(Of LockableDataObject) = New BusinessManager

End Sub

End Module

This is the error you must be getting. Follow the classes and what inherits which and what are the arguments.

Value of type 'Module1.BusinessManager' cannot be converted to 'Module1.LockableDataManager(Of ConsoleApplication1.Module1.LockableDataObject)'.
