Demos for Windows PowerShell compatibility with PowerShell Core 6

demo_windows_compat.ps1

# Single script for Windows PowerShell and PowerShell Core

## Use PSEdition

@'
if ($PSVersionTable.PSEdition -eq "Core")
{ "PowerShell Core!" }
else
{ "Windows PowerShell!" }
'@ > both.ps1

## Handling breaking changes

### Get-Content example

Get-Content ./both.ps1 –Encoding Byte
Get-Content ./both.ps1 –AsByteStream

### Leverage PSEdition and splatting

@'
$IsPSCore = $PSVersionTable.PSEdition -eq 'Core'
$params = @{ Path = './content.ps1' }
if ($IsPSCore)
{
    $params += @{ AsByteStream = $true }
}
else
{
    $params += @{ Encoding = 'Byte' }
}

Get-Content @params
'@ > ./content.ps1
