An Out-Grid cmdlet implemented in what may possibly be the most complicated fashion ever ;-) David Barnhill has created a WPF app which you can instantiate from PowerShell by sending output to it... but the cmdlet actually creates a separate application object (a new process) and then communicates with it (using WCF) to send it the grid data.
Some cool tech there, but it seems like he might as well have made Out-WPFGrid into a stand-alone app -- and it seems like that would have been easier?
Possibly the most dissoriented interview I've seen from the guys at powershell. Not only does he incorrectly imply there aren't any launched third party application vendors, but they literally never discuss the headline.
How to handle Events in PowerShell (another example of things you just can't do in a string based shell?) a GREAT example of how using PowerShell leads to .Net programming (and how knowing .NET programming translates into knowing PowerShell).
