'DontShow' property specified was not found

[craig-wagner]

I just used the Web Platform Installer to install "Microsoft Azure PowerShell - November 2015" (v1.0.1) on Windows 7. I went to the start menu and clicked "Microsoft Azure PowerShell" to start a session. The first thing I did was type "get-help azure". I got a list of commandlets up to "New-AzureStorSimpleStorageAcco..." at which point the list was terminated with the following error.

get-help : 'DontShow' property specified was not found.
At line:1 char:1

• get-help azure

• - CategoryInfo          : NotSpecified: (:) [Get-Help], CustomAttributeFormatException
  - FullyQualifiedErrorId : System.Reflection.CustomAttributeFormatException,Microsoft.PowerShell.Commands.GetHelpCommand
  
  

I used to have v0.9 installed but I checked "Programs and Features" and the only version listed as being installed is the November 2015 one identified above.

@hovsepm I'm not familiar with the DontShow attribute parameter on the [Parameter()] attribute. Is this a valid parameter? The problem seems to be on the following line:

azure-powershell/src/ServiceManagement/StorSimple/Commands.StorSimple/Cmdlets/VirtualDevice/NewAzureStorSimpleVirtualDeviceCommand.cs

Line 45 in f2674a6

[Parameter(DontShow = true, Mandatory = false, HelpMessage = StorSimpleCmdletHelpMessage.PersistAzureVMOnFailrue)]

@pcgeek86 @craig-wagner See: http://www.powershellmagazine.com/2013/07/29/pstip-hiding-parameters-from-tab-completion/

This was added in PowerShell 4.0, which is why it would only show up in windows 7. We should make sure this attribute is removed until we officially require wmf 4 OR wmf 5

Root Cause

Some cmdlets have 'Dont'Show' as a property in the parameter attribute declarasion

Proposed Solution

• Check for this property in static analysis and reporta P1 (build break) issue if found
• Remove Dont'sSHow from cmdlets that have it through filling issues with their owners
