The LazyStack tools are available as .NET Tools and as a Visual Studio IDE (Windows) Extension.
The .NET Tools command has this syntax:
lazystack settings <stackname> [<filepath>] [-p <profilename>]
This command is also available in the Visual Studio IDE (Windows) Tools menu.
This command uses AWS Cloud Formation to retrieve settings from the specified <stackname> and then write these settings out to "AwsSettings.json" or to the specified <filepath>. Your "default" AWS profile will be used unless you specify a different profile with the -p option.
