Leon the SecretGeek has the PowerShell bug and has beat me to a great idea. A documentation browser for PowerShell. We're automating PowerShell at Corillian in a number of ways that I'm sure I'll be posting on over the next few months. (Maybe I'll do a few screencasts on hosting PowerShell...Lee Holmes has a great Logo example here.)
His application hosts a PowerShell runspace and runs the PowerShell "get-command" cmdlet, capturing the output and presenting it ala MSDN in a listbox. Then as you click on a command he invokes "help <commandname>" and sends the output to his text boxes. Quick, dirty and fabulous.
Thanks Leon, what a great way to make learning PowerShell easier using the excellent pithy help that's trapped within the command-line.
