Question

Are there any exception logging components in Windows Phone applications? Do you have any suggestions about logging records in Windows Phone applications?

Answer 1

For logging to Visual Studio while running, you can use Debug.Write.

As far as logging exceptions to a file, WP7Contrib has an exception logging library that is available as part of WP7Contrib.Core on NuGet. WP7Contrib.Core’s only dependencies are the Rx libraries.

Edit: You can use the WP7Contrib logging library like this:

private ILogManager logManager = new LoggingService();

private void Application_Launching(object sender, LaunchingEventArgs  e)
{
    logManager.Enable();
}

private void Application_Activated(object sender, ActivatedEventArgs  e)
{
    logManager.Enable();
}

private void Application_Deactivated(object sender, DeactivatedEventArgs  e)
{
    logManager.Disable();
}

private void Application_Closing(object sender, ClosingEventArgs  e)
{
    logManager.Disable();
}

Edit 2:

Having said that, I’d probably just use an extention method:

// App.xaml.cs
private ILogManager logManager = new LoggingService();

public App()
{
    logManager.Attach(PhoneApplicationService.Current);
}

// LogManagerExtensions.cs
public static class LogManagerExtensions
{
    public static void Attach(this ILogManager logManager, PhoneApplicationService appService)
    {
        appService.Launching += (s,e) => logManager.Enable();
        appService.Activated += (s,e) => logManager.Enable();
        appService.Deactivated += (s,e) => logManager.Disable();
        appService.Closing += (s,e) => logManager.Disable();
    }
}
