The Community Technology Preview #2 (CTP2) of Windows Management Framework 3.0 available through Download Center "makes some updated management functionality available to be installed on Windows 7 SP1 & Windows Server 2008 R2 SP1," revealed PowerShell Team.
Windows Management Framework 3.0 contains Windows PowerShell 3.0, WMI & WinRM.
"This software is a pre-release version. Features and behavior are likely to change before the final release," Microsoft stated.
Adding, "This preview release is designed to enable the community to experience and review the preliminary designs and direction of key features in Windows PowerShell 3.0 and to solicit feedback before features are finalized," the Redmond company said.
Some of the new features in Windows PowerShell 3.0 include:
- Workflows that run long-running activities (in sequence or in parallel) to perform complex, larger management tasks, such as multi-machine application provisioning. Using the Windows Workflow Foundation at the command line, Windows PowerShell workflows are repeatable, parallelizable, interruptible, and recoverable.
- Robust Sessions that automatically recover from network failures and interruptions and allow you to disconnect from the session, shut down the computer, and reconnect from a different computer without interrupting the task.
- Scheduled Jobs run regularly or in response to an event.
- Delegated Administration commands that can be executed with a delegated set of credentials so users with limited permissions can run critical jobs
- Simplified Language Syntax make commands and scripts look a lot less like code and a lot more like natural language.
- Cmdlet Discovery and automatic module loading that make it easier to find and run any of the cmdlets installed on your computer.
- Show-Command, a cmdlet and ISE Add-On that helps users find the right cmdlet, view its parameters in a dialog box, and run it.
WMI on Windows Management Framework 3.0 introduces:
- A new provider development model brings down the cost of provider development and removes the dependency on COM.
- A new MI Client API to perform standard CIM operations.
The API can be used to interact with any standard WsMan + CIMOM implementation, allowing management applications on Windows to manage non-Windows computers.
- The ability to write Windows PowerShell cmdlets in native code
The new WMI Provider APIs supports an extended Windows PowerShell semantics API allowing you to provide rich Windows PowerShell semantics. e.g., Verbose, Error, Warning, WhatIf, Confirm, Progress
With Windows Management Framework 3.0:
- Connections are more robust
Session disconnect and reconnect, with or without client session reconstruction, allows long-running tasks to continue even when the session in which they were started is closed and the client computer is shut down. This feature also allows administrators to reconnect from different computers to check the status of remote running tasks and get results.
- Connections are more resilient
In Windows PowerShell 3.0, connections can survive short-term network failures; the client-server connection is not severed at the first sign of trouble. If network problems persist, the client is safely disconnected and can reconnect by using the Connect-PSSession or Receive-PSSession cmdlets.
Windows PowerShell Web Service enables an administrator to expose a set of PowerShell cmdlets as a RESTful web endpoint accessible via the (Open Data Protocol (OData). This provides remote access to invoke cmdlets from both Windows and non-Windows clients.
