In PowerShell 3.0, you finally can extend object types dynamically without having to write and import ps1xml-files. Here is an especially useful example:
PS> $code = { $url = 'http://msdn.microsoft.com/en-US/library/{0}(v=vs.80).aspx' -f $this.GetType().FullName Start-Process $url } PS> Update-TypeData -MemberType ScriptMethod -MemberName GetHelp -Value $code -TypeName System.Object
Once you execute this code, every single object has a new method called GetHelp(), and when you call it, your browser will open and show the MSDN documentation page for it – provided the object you examined was created by Microsoft, of course. There are many ways how you can call GetHelp(), for example:
PS> $thedate = Get-Date PS> $thedate.GetHelp() # <- opens browser with MSDN help for DateTime data type PS> (Get-Date).GetHelp() # <- opens browser with MSDN help for DateTime data type
