How can I find what Static Classes and Methods there is available in PowerShell 2.0?
You have the classes ( static or otherwise ) from .NET framework.
Once you have the class, you can use Get-Member
:
[Environment] | Get-Member
PS: "Windows PowerShell Cookbook" by Lee Holmes has an Appendix which lists some useful classes, from Powershell / SysAdmin point of view. That list( and the book) is very useful.
