cilc generates C GObject bindings for .NET assemblies. It features optional integration with the Gtk# gapi C# binding generator to roundtrip inheritance hierarchies.
The man page is currently the best source of information.
 Known issues
OS X, Win32 due to inflexible build system
No explicit 2.0 support. Will break in cases where generics are used in a public API but should otherwise work with other 2.0 assemblies.
