Failing azure webjob

Question!

My Azure WebJob keeps failing consistently with the exit code -2146232576. Does anyone know what the exit code relates to?

I'm trying to run it on a schedule, and my source code can be found here:

https://github.com/luke-barnett/trakt-imdb250/tree/master/TrakIMDB250.Scraper

Relevant logs:

My problem was that I was flying too close to the sun trying to run .NET 4.6.

Downgraded the solution to 4.5.2 and it worked perfectly :)

Note: this solution is bound to become irrelevant once 4.6 is officially supported.
