A trivial Gtk# application, essentially a 'Hello world' for using Gtk# with C# threads.
Click the button to spin up a few C# threads, which then sleep for various numbers of seconds and then adjust the value of the slider.
Included are the files needed to load the code as solution in MonoDevelop or Xamarin Studio.
Untested in Visual Studio, but the MonoDevelop solution should work as a VS2008 project ( see http://www.monodevelop.com/help/faq/ ).
