Now you are ready with the Worker role project.

Purpose of Worker Role

The Worker role can be used to host WCF services, provide endpoints, perform operations etc.

The default Run() method implementation contains an infinite loop as shown below:

public override void Run()

{

// This is a sample worker implementation. Replace with your logic.

Trace.WriteLine(“WorkerRole1 entry point called”, “Information”);

while (true)

{

Thread.Sleep(10000);

Trace.WriteLine(“Working”, “Information”);

}

}

Now execute the application and you will be able to see the application inside the browser. From the system tray, you can verify the Windows Azure Emulator as running.

If successfully executed, you can see the trace output messages as shown below.
