What's in this chapter?
Modern, multitasking operating systems often need to run applications that operate in the background and that are independent of the user who is logged in. For example, an application that provides a service interface to obtain data needs to service external requests for data regardless of whether there is a current user.
Over time, the number of choices to implement application services has increased. Originally, the main choice was Windows Services, but other choices have been added as .NET and Windows have evolved. Keep in mind that Windows Services aren't something you are going to access in a purely client environment like Windows 8 RT.
