webapi only return 1 record

[juchunwei]

I don't know what's wrong. I did the http get method:

var chks = _context.CheckListForUsers.Include(c => c.CheckList).ToList();
return chks.

I can see there're 3 records, but only shows 1 if I open it with browser or on my client app.

but if I remove Include(c => c.CheckList), I can get 3 records.

what's wrong?

Thanks,

If you turn on logging to you see any exceptions logged? This issue may be related: aspnet/Mvc#5413

@Tratcher, thanks, but could you tell me how to turn on logging?

Add the console logger: https://docs.asp.net/en/latest/fundamentals/logging.html

Also, if you're using IIS/Express you'll need to enable stdoutLogEnabled in the web.config.
