In this recipe, we will look at creating a simple way to make sure you're aware of any exceptions your web services are throwing. We will write our own implementation of ILog and ILogFactory that ServiceStack provides as a generic way of logging information.
We have had mixed experiences with e-mail loggers in large-scale production environments—it's not a great practice unless a significant amount of sophisticated logic goes into figuring out which errors constitute something interesting, and which don't. Having said that, it's still a useful technique for smaller applications and makes a great example for how to structure your own logger.
First, we will need some services to work with. In this example, we will use GreetingService, so we can focus on how we can incorporate our e-mail logger to the application.
