現在、Host (コマンド) で生じた例外はハンドリングせずそのまま外に放出している。
仮に外側でもハンドリングしないでいると、ConsoleLogger の内部キューを経由せずに直接 コンソールに例外が書き出されてしまいログ表示が崩れる。
よって Host (コマンド) 内部で生じた例外を安全にコンソールに出力、又は IHostBuilder.InvokeAsync()
の呼び出し側からハンドリングできるような仕組みが欲しい。
ICommand
はコンソール コマンドを意図しているが、CQRS のコンテキストで併せて使うとそちらの Command と区別がつき難い。

namespace を Inasync.Hosting
にしたつもりが漏れてたので修正
https://github.com/in-async/Hosting.Command/blob/10bf3cb39d51d8e1a4e6c91edc7de9da333d923b/Inasync.Hosting.Command/ICommand.cs#L4-L10
Task.Run() のデリゲートで ValueTask
を返している為:
Task
を返すようにすれば解決:
await Task.Run(() => {
if (host is IAsyncDisposable asyncDisposable) {
return asyncDisposable.DisposeAsync().AsTask();
}
host.Dispose();
return Task.CompletedTask;
}).ConfigureAwait(false);
