C# Class GpsBroadcaster.Task

A class that represents a unit of work to be done. At the choice of the user, this can either be executed synchronously on the current thread or the GUI thread, or be executed asynchronously on a background worker. In either case, it will be able to report back on the GUI thread when the work is done. And if you choose to use an asynchronous operation, then it can also report back progress.
