Large JSON response truncated from Azure API app (.NET Core)

Question

I have a standard .NET Core API Controller that returns JSON.

All works as designed but with larger data sets the response is being truncated.

I cannot work out (or find on Stackoverflow or elsewhere) how to increase the limit - presuming this is the cause.

Can someone point me in the right direction please?

did you try to setup maxJsonLength in web.config? http://stackoverflow.com/a/1151993/2833802 and maybe http://stackoverflow.com/a/3853785/2833802 — Set, Jul 01 '16 at 12:30
I did try that. May have got a typo or something so will try again — Mark Chidlow, Jul 01 '16 at 12:32
@Set: Question is about ASP.NET Core, the linked answer is for legacy ASP.NET which also uses web.config as settings file. — Tseng, Jul 01 '16 at 15:44
@MarkChidlow, Could you use the Fiddler to trace your result? And Would you like to share your json result size ? — Will Shao - MSFT, Jul 18 '16 at 06:55

I had a similar issue and what seemed to fix it was setting the 'ReferenceLoopHandling' JSON setting:

public void ConfigureServices(IServiceCollection services)
{
        services.AddMvc().AddJsonOptions(options => {
            options.SerializerSettings.ReferenceLoopHandling = ReferenceLoopHandling.Ignore;
        });
 ...
}
