This question already has an answer here:

How do I write to the logs in Azure WebJobs from a C# console app? 2 answers

So I have tried:

Trace.TraceInformation("Trace.Information Found message on queue");
Debug.WriteLine("Debug Found message on queue"); 
Trace.WriteLine("Trace.WriteLine Found message on queue");
Console.WriteLine("Console.WriteLine Found message on queue");

But neither of them outputs to the Azure portal Web Jobs output log.

What am I missing?

Later edit: Since the Beta version, the answer below is no longer correct. In order to log messages, you have to use a TextWriter now as shown in these samples: https://github.com/Azure/azure-webjobs-sdk-samples/blob/master/BasicSamples/MiscOperations/Program.cs

Console.WriteLine should work. If that doesn't work, can you please post more code?

For messages written from inside a function, the logs should show up on the function invocation page.

For messages written outside of a function, the logs should show up in the job output log.

回答2:

Console.WriteLine worked for me but log.WriteLine (as per the SDK samples) did not.

Turned out I needed to set the Webjob connection strings in the portal even though I had AzureWebJobsDashboard and AzureWebJobsStorage defined in the App.config.
