Issue Description

Steps to Reproduce:

1.Run the command block below
2.Enter random text when prompted in the console
3.You get an error saying that powershell crashed

If you launch the same code in the ISE you will get an error in the console saying that the switch param will not accept a string. However, the shell will not crash.

[cmdletbinding()]
param(
    [Parameter(Mandatory = $true, HelpMessage = 'test')]
    [Switch]$ServerName,

    [Parameter(Mandatory = $true, HelpMessage = 'test')]
    [Switch]$Server2Name

)#End cmdletbinding
