Assembly.GetEntryAssembly() is documented (MSDN) to return null is
called outside the default appdomain (*) or if the assembly was loaded
from an unmanaged host application.

(*) the entry assembly may not be loaded in the current appdomain

Again this looks like an easy Gendarme rule that would be useful for
library writers ;-)
