    Notes from: https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_object_creation?view=powershell-7
    You can create an object from a hash table of properties and property values.
 
    The syntax is as follows:
 
    [<class-name>]@{
    <property-name>=<property-value>
    <property-name>=<property-value>
    }
 
    This method works only for classes that have a parameterless constructor. The object properties must be public and settable.
