[Question] Retrieve all Configurable rules

[LaurentDardenne]

I try to retrieve all configurable rule with this code, but the 'AvoidAlias' rule is missing, should not this rule be of the ConfigurableRule type ?

$sb= {dir}
#Force Dll Loading
Invoke-ScriptAnalyzer -ScriptDefinition $sb.ast

$BuiltinRules= [System.AppDomain]::CurrentDomain.GetAssemblies()|? location -match 'Microsoft.Windows.PowerShell.ScriptAnalyzer.BuiltinRules'
$BuiltinRules.GetTypes()|? {$_.IsSubclassOf([Microsoft.Windows.PowerShell.ScriptAnalyzer.Generic.ConfigurableRule])}

The correct and easier way to retrieve all rules is Get-ScriptAnalyzerRule.
The alias name that you are looking for is PSAvoidUsingCmdletAliases, therefore you can retrive it using Get-ScriptAnalyzerRule -Name PSAvoidUsingCmdletAliases
I don't understand your question about ConfigurableRule type. Can you please elaborate in case this answer has not solved your question please.

I don't understand your question about ConfigurableRule type.
Ok.

1-The AvoidAlias class should they not be inherited from the class ConfigurableRule ?
2-Today Get-ScriptAnalyzerRule can not filter configurable rules. The documentation says 'Rule' and 'Severity' but not if the rule is configurable.

Aha, I see now what you mean. Yes, I think you are right that the rule should probably inherit from ConfigurableRule but filtering configurable rules in Get-ScriptAnalyzer sounds more like a new (but useful) feature to me.
