Cheers for testing it out, I've merged this branch into master along
with a few small bugfixes that I'm pretty sure are safe :+1:

Yeah it's pretty odd. I have an Ubuntu 17.10 virtual machine that I
had installed ages ago and running monodis on the gudev-sharp.dll from
the 3.0 package shows that it contains no namespace and no types.

I think I encountered this problem with my own system (Gentoo) but I
was able to patch the ebuild (ebuild is just the Gentoo term for
package) to fix it. You should see .namespace GUdev somewhere in the
output from monodis if you have a working assembly.

If it makes any sense to you this is the modification that I made in my ebuild:

sed -i 's#GENERATED_SOURCES=generated/\*.cs#GENERATED_SOURCES="generated/GUdev/*.cs
generated/GtkSharp/*.cs"#' configure.ac

In summary, the sources are probably being generated but the
GENERATED_SOURCES variable doesn't refer to them since they're in
subdirectories, #Fail...
