If you want to use WIA in WinForms just add a refernce to wiaaut.dll. You have to download the WIA dll from Microsoft.com and then browse to the dll and add it to your project. I am assuming that you are specifically talking about the scanner/camera functionality. Otherwise you can use other methods to accomplish the other functionality. @Wajid

Macs do have similar access to COM using AppleScript. There is a rumor in the air that Microsoft has stated that they will try to support COM interop in Macs with SL 4 RTM. In order to do this I suspect they will either allow executing AppleScript, or extend the ComAutomationFactory class to return ApplScript objects. Even if they don't support COM for Mac, doesn't it make sense to at least support the OS and applications they make? Chances are if your doing Microsoft Office interop, your not on a Mac. @punkcoder

Silverlight was supposed to be this competitor to Flash for creating RIAs that run on Windows and Mac, and Linux through Moonlight. Once they add COM support, they are starting down a road of platform specific features.
