Introduction

This article explains how to create a simple background agent in Windows Phone. There is a MSDN example on how to create a background agent but its not simple it has additional stuff in it, so if you are looking for just plain simple how to ? here it is.

Basic requirements

You need to create an app project , it can be anything from simple basic windows phone app to panorama or pivote based application. Then create your background agent project in the same solution and add its reference to the main app, with necessary code ( which is hardly few lines) you can have your background agent running. You can test agents in simulator as well.

How to....

• Create a simple windows phone application project as follows and give some suitable name to it.

• Create a scheduled task agent project in Visual Studio, this should be added to the same solution , an easy way to do is, goto solution explorer of main application right click on solution and select add, select add project and automatically the project created will get added to the existing solution. Assign some suitable name to the project.

• Next step is to add a reference to the main application it can be done by going to Solution Explorer, right click references under main project and select Add Reference option.

• Next select Solutions section on the Add Reference dialog and you should be able to see the name of your scheduled task agent project name there select it and its done.

• Next open ScheduledAgent.cs file from your background agent project and add following lines of code in OnInvoke method

[code lang=csharp]

 string toastMessage = "Periodic task running.";

           ShellToast toast = new ShellToast();
           toast.Title = "Background Agent Sample";
           toast.Content = toastMessage;
           toast.Show();

1. if DEBUG_AGENT

 ScheduledActionService.LaunchForTest(task.Name,TimeSpan.FromSeconds(60));

1. endif

           NotifyComplete();

[/code]
