Guidance on registering slash commands per guild with NetCord.Hosting.Services

[sillock1]

Description

This change has broken the ability to register slash commands using the SlashCommandAttribute on a per guild basis. I currently follow this guidance in your docs alongside custom bases for registering http interaction commands using annotations.
What is the preferred way to register http interactions on a per guild basis to allow for "local" testing?

Hi, I think we might think of explaining how to register app commands to guilds (cc @Mewyk). For now you can see this example:

var services = host.Services;

var service = services.GetRequiredService<ApplicationCommandService<HttpApplicationCommandContext>>();

var client = services.GetRequiredService<RestClient>();

var properties = await Task.WhenAll(service.GetCommands().Where(c => c.Name is not ("some" or "filter" or "if" or "needed")).Select(c => c.GetRawValueAsync().AsTask()));

ulong guildId = 856183259972763669;

await client.BulkOverwriteGuildApplicationCommandsAsync(((IEntityToken)client.Token!).Id, guildId, properties);

Also you will probably want to set AutoRegisterCommands to false in the configuration.

That said, I think local testing should be done on a separate Discord application (bot).

I think this code may also be helpful. The example above is a bit outdated and more complicated.

var client = host.Services.GetRequiredService<RestClient>();

// make sure the minimal API style commands are added
foreach (var commandsBuilder in host.Services.GetServices<IApplicationCommandsBuilder>())
    commandsBuilder.Build();

ApplicationCommandServiceManager manager = new();

// add registered services to the manager
foreach (var service in host.Services.GetServices<IApplicationCommandService>())
    manager.AddService(service);

ulong guildId = 856183259972763669;

// you can also get the application ID using ((IEntityToken)client.Token!).Id
// if the token is IEntityToken, or using gatewayClient.Id if you use the GatewayClient
ulong applicationId = 856183259972763668;

// register the commands
await manager.RegisterCommandsAsync(client, applicationId, guildId);
