Since Windows 7 and Windows Server 2008 R2, Windows PowerShell has been a part of the core operating system, meaning we will see the next version of PowerShell in Windows 8. In this session we will look at what`s new in Windows PowerShell 3.0, based on the Windows Developer Preview released at the BUILD conference in September. You will get to see new features in PowerShell itself, as well as new modules for managing Windows 8 and Windows Server 8.

 Show-Command

10. WMI in Windows Management Framework 3.0
 A new provider development model
This new 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

11. WinRM in 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.
 Connections are more resilient
In Windows PowerShell 3.0, connections can survive short-term network failures.

12. Microsoft Connect (connect.microsoft.com/powershell)

13. DEMO
Let`s have a look at the new features in action

14. Windows PowerShell Web Service
 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.

15. Windows PowerShell Web Access
 The PowerShell console exposed as a website
 Use PowerShell from mobile devices
 Available in «Windows Server 8»

16. Windows PowerShell Workflow
 Windows PowerShell Workflow lets IT pros and developers apply the benefits of
workflows to the automation capabilities of Windows PowerShell.
Getting Started with Windows PowerShell Workflow
A workflow is a sequence of automated steps or activities that execute tasks on or
retrieve data from one or more managed nodes (computers or devices). These activities
can include individual commands or scripts. Windows PowerShell Workflow enables, IT
pros and developers alike, to author sequences of multi-computer management activities
— that are either long-running, repeatable, frequent, parallelizable, interruptible,
stoppable, or restartable — as workflows. By design, workflows can be resumed from an
intentional or accidental suspension or interruption, such as a network outage, a reboot
or power loss.
