This sort of code makes me very angy!

Tell me what’s wrong with this simple piece of code:

public class MyService : IMyService, IDisposable 
{
    private readonly IOtherService _otherService;
    public MyService(IOtherService otherService)
    {
        _otherService = otherService;
    }

    public void Dispose()
    {
       _otherService.Dispose();
    }
}

The answer is very simple: “I created you and I will be your end”, yet MyService didn’t create IOtherService, thus it has not right to call Dispose() on the service.”

Yet, at Mizuho, I saw many developers lacking this simple, yet critical design concept!
