.NET Core Hosted Example

Quick Start

To start, you need to configure the entry point to the application:

public class Program
{
  private static int Main(string[] arguments) =>
    CommandLine
      .CreateFromArguments(arguments)
      .Use<Program>() // set class with verbs/commands
      .Run();

  public static int Hello(string name)
  {
    Console.WriteLine("Hello " + name + "!");
    return 0; // exit code
  }
}

Full Example Code

CommandLine relies on reflection to find method to invoke.
This method should return int value which is interpreted as Exit Code of application.
Asynchronous entry points and methods are also supported. To do this, use method RunAsync() and Task<int> as return type.

When you could request help for your application:

> myapp /?

This test application. Type /? for help.

  Verbs:
    HELLO    Says hello to specified 'name'.

Or invoke Hello(string name) with following command:

> myapp hello --name Jake

Hello Jake!
