static int Main(string[] args)
{
return Parser.Default.ParseArguments<Options>(args)
.MapResult(
options => RunAndReturnExitCode(options),
_ => 1);

Parsing with async
|
|
public static async Task Main(string[] args)
{
await Parser.Default.ParseArguments<Options>(args)
.MapResult(
async options => await RunAndReturnExitCodeAsync(options),
_ => Task.FromResult(1));
|
Command line
 |
In case of missing or unknown argument or parsing error, the errors are displayed with the usage explanation message and the application exits. |

By default options --help and --version are available. |
