Just learning about parameters in Powershell and came across this error:
Unable to find type [Parameter]: make sure that the assembly containing this type is loaded
Yes, I am running Powershell v2.0 and no I did not easily find any reference to this in my searches.
Through some trial and error, I figured out that in my Param() declaration, I had this:
The "[Parameter]" declaration was the culprit. My other ones had [Parameter(Mandatory=$true)]. So, I just removed the line and all works fine again.
