Hello fmor-zz, I'm not from Facebook but I am guessing that you have some .cs or .mm files left over from before facebook updated to dlls. I suggest that you first make a backup of your project, then delete the entire FacebookSDK folder, any leftovers that facebook installed to the plugins directory (Basically, anything that you suspect came with facebook sdk then finally reimport the unitypackage.

If this is a fresh install of the sdk ( as in, you did not have a earlier version installed ) please completely ignore my statement above.

I would like to mention (for what its worth) I am using the 7.8.0 sdk and am running on iOS. I had to manipulate some things because I am not on el capitan but i think thats irrelevant to what you are running into.

Happens to me as well. Any idea how to work around it?

Hey, I've read that reverting to 7.7.0 fixes the issue.

I wanted to know if upgrading from 7.8.0 to 7.9.0 fixes it?

I too was using Facebook SDK 7.8.0 and upgrading to 7.9.4 fixed this, on Unity 5.5.3p3. I am now able to debug on an iOS device using MonoDevelop and building with Mono2x selected in the player settings
