My vocabulary is way to small to express my feelings when being forced to use .Net 4.0. Just spent like 2 hours searching why my Api requests failed.
Turns out it used TLS 1.0 which got rejected by the server. Then I spent another 2 hours finding out how to make it use TLS 1.2. Surprisingly it does work now (although it came out before TSL 1.2 specification). But yeah still a fucking pile of shit.
