new 3.0 PowerShell offers interesting new scriping capabilities, New Windows PowerShell 3.0 version in preview mode
Die-hard MS pre-release technology consumers already know that CTP is shorthand for “Community Technology Preview,” a pre-beta technology release stage that usually seeks to help developers become familiar with and prepare for important coming Microsoft technologies. Timed to coincide with the Developer Preview for Windows 8 (which shares a common code base with Windows Server, lest anybody forget that scripting languages are more important for servers than desktops, by and large), there’s a CTP for Windows Management Framework 3.0 now available, and it includes a reworked version 3.0 of the Windows PowerShell scripting language that offers some pretty cool new features and capabilities.
There’s a nice post to the Windows PowerShell Blog entitled “Windows Management Framework 3.0 Community Technology Preview (CTP) #1 Available for Download” that explains all this stuff in more detail, but here are some high points of what the latest iteration of PowerShell 3.0 is going to deliver:
- Support for workflows that can “perform complex, large management tasks such as multi-machine application provisioning.” Also “Windows PowerShell workflows are repeatable, parallelizable, interruptible, and recoverable.”
- Support for robust sessions, means that PowerShell sessions can “…automatically recover from network failures and interruptions…” and more.
- Simplified language syntax for PowerShell 3.0 makes “…commands and scripts look a lot less like code and a lot more like natural language.”
- Extensions to support cmdlet discovery, automatic module loading, and a new Show command that provides easy methods for users to find and use cmdlets properly
You’ll also find changes to the Windows Management Framework (aka WMI), including a new provider development model that makes it easier to build service providers, and extends management applications running on Windows outside the Windows umbrella. Likewise, remote management (WinRM) has also been extended to include more robust and resilient client sessions, for more comprehensive and robust remote management facilities. There’s even a PowerShell Web Service that offers remote access for calling cmdlets from Windows or non-Windows clients. Way cool!
