AppRunner<object>.Run(args) returning error (1) in dotnet6 and shutting down

[asheesh1996]

 static void  Main(string[] args)
        {
            Console.WriteLine("Starting Application :)");
            var op = new AppRunner<Calculator>().Run(args);
            Console.WriteLine(op);

        }

Hi @asheesh1996 the documentation has fallen behind a bit and I've been working to update it. I just merged a branch to master with updated Getting Started docs that should work for you. Let me know if there are still problems.

[drewburlingame]

@asheesh1996 has the updated documentation been helpful? Are you still having problems?

[asheesh1996]

Hi @drewburlingame , I tried the updated documentation, following is the code snippet

using CommandDotNet;

namespace CommandLineTest
{

    public class Program
    {
        // this is the entry point of your application
        static int Main(string[] args)
        {
            // AppRunner<T> where T is the class defining your commands
            var OP = new AppRunner<Program>().Run(args);
            Console.WriteLine(OP.ToString());
            return OP;
        }

        // Add command with two positional arguments
        public void Add(int x, int y) => Console.WriteLine(x + y);

        // Subtract command with two positional arguments
        public void Subtract(int x, int y) => Console.WriteLine(x - y);
    }

}

And application is closing with following output

Usage: CommandLineTest.exe [command]

Commands:

  Add
  Subtract

Use "CommandLineTest.exe [command] --help" for more information about a command.

How are you executing the app? If you're not passing in a command to run or a help option, this is the expected behavior because CommandDotNet is not able to execute a command since there's no default command and no subcommand was specified. It prints the help as a courtesy. If you typed in CommandLineTest.exe -h or CommandLineTest.exe --help then you'd get the same output but OP would be 0. If you typed CommandLineTest.exe Add 1 1 then it should print 2 and OP would be 0.

[drewburlingame]

What I'll do is follow the convention used by the dotnet tool and print Required command was not provided. when this happens, and then the help text.

[drewburlingame]

This will go out with our next release.

[drewburlingame]

I've pushed 6.0.1. I'll close this for now. Reopen if the cause is different than what I've stated above.

[asheesh1996]

Thanks for the response, I was using it in the wrong way. I got it working .

Good to hear you got it working. Feel free to start up a discussion of you have questions or challenges.
