A fix for this will be in the next release, however you can fix the c# by doing the following:

Change lines 2894 and 2974 of CaptureBase.cs from:

#if ENABLE_IL2CPP

to:

#if ENABLE_IL2CPP && (UNITY_STANDALONE_OSX || UNITY_EDITOR_OSX || (UNITY_IOS && !UNITY_EDITOR))

4.7.7 has now been released with the fix for this issue
