Description Rodrigo Moya 2017-03-08 17:19:11 UTC
With 15.1 Alpha 2 update, it's impossible to profile tvOS application, as it seems the included libmono-sgen.dylib is wrong or truncated:

Application crashes as soon as started:

Same app profiled on Mac via XS works, so I guess something's wrong on the build/ssh copy steps in VS when building the app?
Comment 1 Rodrigo Moya 2017-03-08 17:22:05 UTC
BTW, running apps results in the same error
