How to use a third party framework in Xamarin project.

I have a mac project created in Xcode that is using a third party framework in it osxfuse Now I want to port this project to Xamarin. How should it convert it.

Try 1. I used a Xamarin tool named objective-sharpie and it take location of the header files and give a file without any extension. I am not sure how to use that in my Xamarin Project.

Try 2 should I create a static lib ".a" file for my project and convert that to xamarin, but how the framework would be used in Xamarin project.

Thanks
