The problem with that is I would have had to change the public property to be UInteger which would not longer be compliant with the original functionality of the class. Add to that the Initialize() method would has to be changed as well.

However, when moving that at the Framework level, at this line:

Imports System.IO

Namespace Framework

    Public Class CRC32VFP

        Public cMessage As String = ""
        Public cFileName As String = ""
        Public lLogError As Boolean = True
        Public nCRC32 As UInteger = 0

I have: "Type of member 'nCRC32' is not CLS-compliant."

I understand this might be normal as in VB.NET, this is as is. But, I didn't get that warning when I tested it in a test application.
