Presumably as suggested at:


Please don't do that; please follow the Application Deployment Guidelines and use a shell script wrapper:


The reason being for increased compatibility across Unix platforms, and because (as you note), it doesn't work "properly":

Why? I'm not entirely sure, but I would guess that binfmt works by having the kernel execute a "helper" program located in /usr/sbin, and the helper in turn is responsible for executing mono + the assembly, which may screw up mono's normal logic. The fact that it "screws things up" is documented at the above urls; _why_ it screws things up is not.
