XO.Console.Cli.Extensions 5.0.9

XO.Console.Cli.Extensions

This library integrates XO.Console.Cli applications with the .NET runtime extensions, including dependency injection and the .NET Generic Host. By default, the integration:

• Adds CommandAppBuilderOptions and ICommandApp to the service collection
• Configures XO.Console.Cli to create instances of command and parameters types using IServiceProvider (which means you can use constructor injection for dependencies)
• Sets the command-line application name to IHostEnvironment.ApplicationName
• Wraps IHost startup and command execution to ensure the application reliably logs critical exceptions and responds to shutdown signals

Getting Started

1. Add a reference

> dotnet add package XO.Console.Cli.Extensions

If your project does not already reference Microsoft.Extensions.Hosting, add that, too.

> dotnet add package Microsoft.Extensions.Hosting

2. Set up and run the host

return await Host.CreateDefaultBuilder(args)
    .RunCommandAppAsync(args, static (context, builder) => {
        builder.AddCommand<GreetingCommand>("greet");
    });

Integration with the simpler IHostApplicationBuilder is also possible. First, add the command-line application to the service collection. Then, build the host. Finally, run the configured command-line application.

HostApplicationBuilder builder = Host.CreateApplicationBuilder(args);
builder.Services.AddCommandApp(static (context, builder) => {
    builder.AddCommand<GreetingCommand>("greet");
});

IHost host = builder.Build();
return await host.RunCommandAppAsync(args);
