I recently ran into the following error message while modifying a PowerShell script:

Invalid assignment expression. The left hand side of an assignment operator needs to be something that can be assigned to like a variable or a property

The cause of the error was that I had added a line of code in front of my param declaration:

        Set
        -StrictMode 
        -Version 
        2
       
        param(
       
        [string][parameter(mandatory=
        $true 
        )] 
        $WebsitePhysicalPath
        ,
