Hi, Mark. We're excited about PowerShell 3.0 and will be fully supporting that release, but the Toolkit team hasn't taken the time to test with CTP1 yet. We had another internal tester report that the Toolkit appeared to run fine on Windows 8 with PowerShell 3.0, so we feel good about that. If you encounter anything that doesn't appear to work, please let us know. In the meantime, we're heads down on C-mode cmdlets and other host-side goodies we think you'll appreciate.
