Functions

So ... remember when I said that we're not introducing any additional functions? I lied. There's one. However, it's very useful ... I swear!

Resolve-Error

I still believe that PSWriteLog shouldn't be required to just run the script. So, here's how you can use Resolve-Error:

try {
    # Do something that throws an error ...
} catch {
    $resolvedError = if (Get-Command 'Resolve-Error' -ErrorAction 'Ignore') {
        Resolve-Error
    } else {
        $_.Exception.Message
    }
	Write-Error ('Failed to do a thing. {0}' -f $resolvedError)
}
