PowerShell v3 – A Quick First Look

Posted on September 14th, 2011 Jonathan Medd 4 comments

A preview (emphasis on the preview) of PowerShell v3 was made available in the early hours of this morning following the announcement at the Build conference. Apparently they are also planning to ship something with it called Windows 8. You can download the Windows Developer preview from MSDN to get an early look at it.

Well we know for sure that it is new:

and it is version 3:
```
$host.version.major
```
And it is a .NET 4 app (CLRVersion)
```
$psversiontable
```
From the standard PowerShell modules we have a total of 248 cmdlets
```
(Get-Command -Module Microsoft.PowerShell.*).count
```
However, there are a total of 239 modules that have shipped in the OS, though a large part of these are CIM based.
```
(Get-Module -ListAvailable -All).count
```
Excluding the CIM modules, there are 44 modules
```
Get-Module -ListAvailable
```
And obviously within each module there is plenty of good content:
```
Get-Command -Module PrintManagement
```
New Feature!

In previous versions of PowerShell if you needed to use a cmdlet from a module you first needed to import the module. In v3 the module is loaded when you type the command – even better, you get tab completion on the command before the module is loaded!

Note how the NetTCPIP module is loaded after a command from the module, Get-NetRoute, is loaded.
```
Get-Module

Get-NetRoute | Out-Null

Get-Module
```
Anyone think I should run a blog series called PowerShell 3.0 One Cmdlet at a Time? It might take a while…..

  Sounds like a good idea although to save you the boredom I’m sure you can batch some Cmdlets together.
  
  Looks as though they STILL haven’t done anything for DHCP, that brand new technology nobody really uses which refuses to be automated

  This was from the client OS, haven’t had chance to look in the server yet with the DHCP role installed…..
