Track System.Diagnostics.Trace logs in Azure portal

Question

In my web application, I use

System.Diagnostics.Trace.WriteLine(...);

for diagnostics. The application is published to an Azure deployment slot. I am wondering where I can find these logs in the Azure Portal (or Visual Studio's cloud explorer).

You first need to activate the Application Logging:

1. Go to your Web App.
2. Go to Monitoring / App Service logs .
3. Enable Application Logging and configure it.
