In R#2.0 build 255, an empty static constructor is marked as redundant,
however the absence of this constructor will cause the class to be
marked with BeforeFieldInit. This might make for subtle different
behavior with respect to the moment of initialisation of the class. Take
a look at http://www.yoda.arachsys.com/csharp/beforefieldinit.html for
more information on the subject.
