Reference to type 'CommandLineConfiguration' claims it is defined in 'System.CommandLine', but it could not be found

Was using Beta5-6 and Hosting 0.4:

await BuildCommandLine()
	.UseHost((IHostBuilder host) =>
	{
		// ...
	})
	.InvokeAsync(args);

static CommandLineConfiguration BuildCommandLine()
{
	var root = new RootCommand();

	// ...

	var config = new CommandLineConfiguration(root);
	config.ThrowIfInvalid();
	return config;
}

Are there any new documentation or samples available?

Looks like you'll need to change this (in my case)

 RootCommand rootCommand =
 [
     updateSolutionsCommand,
     showBotCommand
 ];

CommandLineConfiguration commandLineConfiguration = new(rootCommand);
commandLineConfiguration.Invoke(args);

to this

 RootCommand rootCommand =
 [
     updateSolutionsCommand,
     showBotCommand
 ];

 rootCommand.Parse(args).Invoke();

If you were setting a, now removed, property of CommandLineConfiguration then these have moved to the new InvocationConfiguration type, an instance of which is now available as ParseResult.InnvationConfiguration.

Thank you for the response.

What happened to hosting, is it deprecated? If it is,

• shall we use a built-in hosting model, like the Worker?
• implement a custom IHost and build it using HostBuilder
• do not use a hosting model, just build services/logging/configuration and call InvokeAsync on a ParseResult?

System.CommandLine.Hosting was deleted in #2577.

If you want to use Microsoft.Extensions.Hosting, I'd suggest initialising it only within the action of a command. For one thing, that will minimise the number of assemblies that need to be loaded for command completion.
