You have probably created a windows service or other types of applications where you have code which need to be run in the background to not block the main thread. To do that you have different types of solutions in .NET, for instance Threads, Timers and Tasks. However, you need to construct them manually, make sure that they do not throw unhandled exceptions etc.
Griffin.Framework provides a simpler solution where you only need to implement a small interface. The library also have full support for your favorite inversion of control container, which enables to to use dependency injection in your application services.
