Create a combo command line / Windows service app

Question

What\'s the best way in C# to set up a utility app that can be run from the command line and produce some output (or write to a file), but that could be run as a Windows service

Answer 1

The best way to accomplish this from a design standpoint is to implement all your functionality in a library project and build separate wrapper projects around it to execute the way you want (ie a windows service, a command line program, an asp.net web service, a wcf service etc.)
