NObjective is high-performance bridge between managed .NET and unmanaged Cocoa worlds. It provides automatically generated proxies for all Objective-C classes and can be used to export managed classes to unmanaged Objective-C runtime.

Key features:
 * Lowest processor and memory overheads compared to similar bridges; see project page for performance benchmark results
 * Ability to automatically import Objective-C classes
 * Essential enums and structs are also automatically imported
 * Ability to export .NET Framework classes to Objective-C runtime
 * Ability to rethrow exceptions across runtimes in both directions
 * Ability to work on Mac OS X Tiger, Mac OS X Leopard
