Here’s a neat little thing about Visual Studio 2005 IDE for Visual Basic.Net.  When you implement the IDisposable interface, the following code is automatically created for you.  This is different from other interfaces in that only the code stubs/shell (empty methods) are produced for other interfaces.  The auto-cdoe for IDisposable actually produces the code needed for the entire implementation except for the actual cleaning up of resources.  The private fields, Public Dispose Sub and Finalize come complete with no needed modifications so that nothing gets left out.  However, if you forget to clean up a managed or unmanaged resource in the Private Dispose(bool) method, that's your own fault :). Update: As Blair mentioned in the comments, for C# IDE you can right click on the IDisposable term and pick if you want to explicitly or implictly fill in the stubs for the interface.

 Public Class MyClass
    Implements IDisposable

    Private disposed As Boolean = False

    ' IDisposable
    Private Overloads Sub Dispose(ByVal disposing As Boolean)
        If Not Me.disposed Then
            If disposing Then
                ' TODO: put code to dispose managed resources
            End If

            ' TODO: put code to free unmanaged resources here
        End If
        Me.disposed = True
    End Sub

#Region " IDisposable Support "
    ' This code added by Visual Basic to correctly implement the disposable pattern.
    Public Overloads Sub Dispose() Implements IDisposable.Dispose
        ' Do not change this code.  Put cleanup code in Dispose(ByVal disposing As Boolean) above.
        Dispose(True)
        GC.SuppressFinalize(Me)
    End Sub

    Protected Overrides Sub Finalize()
        ' Do not change this code.  Put cleanup code in Dispose(ByVal disposing As Boolean) above.
        Dispose(False)
        MyBase.Finalize()
    End Sub
#End Region

End Class
