You create an application by using Microsoft Visual Studio 2008 and the .NET Framework 3.5.
The application is hosted on a Web server that runs Microsoft Windows Server 2003. It connects to a third-party system by using Web service calls.
The third-party system experiences occasional unplanned outages. When a system outage occurs, the application must perform the following tasks:
– Log error details.
– Notify an on-call technician.
You need to develop a strategy to perform the required tasks.
