PowerShell variables are not always created by explicit assignments of values.
PowerShell provides other ways like cmdlets New-Variable, Set-Variable,
the Variable provider cmdlets, PowerShell API methods.
Such implicitly created variables may be not seen as created in PowerShell class methods.
Scripts:
- Test-1.function.ps1 - creates a variable by
Set-Variableand works fine without using classes. - Test-2.method.ps1 - uses the similar code with a class method and fails, shows the problem.
- Test-3.workaround.ps1 - shows a workaround for the scenario with classes.
