For programmers who are used to leveraging object oriented techniques, even within modern scripting languages, don’t expect too much from the Windows PowerShell. Here’s a quote from the PowerShell Online Help file:
Class Definition: Declares the name of a class, as well as a definition of the variables, properties, and methods that comprise the class. Although it is possible to create a class in Windows PowerShell, it’s not a very straightforward process and definitely goes beyond the scope of this introductory manual. So, for the time being, forget we even mentioned it.
Yep, that’s a verbatim quote. PowerShell is still a verision 1.0 product so hopefully the situation will improve in future versions of the software.
If you’re looking for more documentation for the Windows PowerShell, here are some references.
The Windows PowerShell 1.0 Documentation Pack includes a getting started guide, a user guide/primer, a quad-fold reference card, and release notes for version 1.0.
Microsoft has a .chm Help file for PowerShell which is a convenient (and searchable) reference to supplement the PowerShell online Get-Help CommandLet. They refer to the .chm Help file as the “Graphical Help File” which you can download by clicking here.
O’Reilly publishes a pocket reference which is a very good source of information for the Windows PowerShell if you are an experienced programmer. They also publish the Windows PowerShell Cookbook for the language which is in the standard O’Reilly Cookbook format that is available for other programming languages.
The Windows PowerShell Technology Center has many other helpful resources if you are getting involved in PowerShell Programming.
The next version of PowerShell, version 2.0, is available in a Community Technology Preview (something like a beta version) by clicking here. And hopefully future versions of PowerShell will provide better support for object oriented freatures of the language.
