> I'm not sure if asp.net core is production ready, I wouldn't use it right now for my projects and I also doubt ( someone correct me if this is wrong ) that established companies are looking for asp.net core devs, it might be quite hard to find freelancing jobs.

I'd agree that major companies are probably not using .NET Core (aside from Microsoft I'd imagine). As far as it being production ready, I believe it's near or at that point. 1.0 shipped in June. My employer is starting the transition from .NET to .NET Core and we're pretty confident that it's ready. Having said that, we don't have anything currently in production so I don't really have much data to back up that statement.
