How to set maxWorkerThreads for WEBPAI Hosted in Windows service

We have WEBApi (dotnet framework 4.6.1) hosted in windows service.

Now we need to setup maxWorkerThreads and maxIOThreads based on number of cores for performance tuning..

Is it possible to setup this information in app.config file itself? Or Please guide me to right place
