Hello evreyone, Is anyone could tell me what's wrong with code snippet. I get an error in vb.net 2005: '1. Create 6 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 Thanks a lot in advance. Jugurten.

That is by design. The fact that B inherits A doesn't make C(Of B) inherit C(Of A).
