Steps to reproduce

Run from CMD the following command
powershell -ExecutionPolicy Unrestricted -File .\somescript.ps1 -someParameter $True

In the script itself i have the following line
[Parameter(Mandatory=$true)] [bool] $installSQL

I tried playing with that line and the arguments in many ways, all fail.. i have to turn this into a string and make the string into a bool :\

Expected behavior

Script starting to work.. :)

Actual behavior

Error Message Cannot process
argument transformation on parameter 'installSQL'. Cannot convert value "System.String" to type "System.Boolean".
Boolean parameters accept only Boolean values and numbers, such as $True, $False, 1 or 0.
