Description
Apparently, Websites has a ScriptsToProcess in psd1 file that looks like this:
@{
"Swap-AzureRmWebAppSlot" = "Switch-AzureRmWebAppSlot";
}.GetEnumerator() | Select @{Name='Name'; Expression={$_.Key}}, @{Name='Value'; Expression={$_.Value}} | New-Alias -Description "AzureAlias"
Unfortunately, `using module` is functionally the same as `Import-Module -Force` in that it runs ScriptsToProcess every time. So when her code runs, if the module has already imported, she gets this:
C:\users\jaiello\Documents\PowerShell\Modules\AzureRM.Websites.Netcore\0.9.1\netcoreapp2.0> Import-Module -force AzureRM
.Websites.Netcore
New-Alias : The alias is not allowed, because an alias with the name 'Swap-AzureRmWebAppSlot' already exists.
