I was afraid from WMI

Until I found Microsoft (R) Management Strongly Typed Class Generator - MgmtClassGen.exe

Microsoft (R) Management Strongly Typed Class Generator Version 1.1.4322.573
Copyright c Microsoft Corporation 1998-2002. All rights reserved.
MgmtClassGen <WMIClass> [options]

         /N <WMINamespace> WMI namespace containing the class. Defaults to root\cimv2
/O <ClassNamespace> .NET namespace in which the class is generated
/L <Generated Language> One of the following. Defaulted to CS
CS - CSharp(C#)
VB - Visual Basic
JS - JScript

         /P <FilePath> Output file path
/M <Machine> Remote computer to connect. Defaults to the local machine

/? Displays this help screen

Example :
MgmtclassGen Win32_Logicaldisk /L VB /N root\cimv2 /P c:\temp\logicaldisk.vb

You can find it under you sdk bin directory, so instead of figuring out the properties of the objects you get a strongly type object to work with.
