I am connecting to a web service via a local network IP address with HTTP scheme.
I was explicitly providing NSUrlSessionHandler to my HttpClient.
I have NSAppTransportSecurity with NSAllowLocalNetworking to YES and NSAllowsArbitraryLoads to YES. Probably don't need both but that is current setting.
Once I updated Xamarin Studio to 6.2, I can no longer connect to my web service via NSUrlSessionHandler.
I have switched for the time being to HttpClientHandler and all works and the plan is to switch eventually to HTTPS, so I should be able to switch back to NSUrlSessionHandler.
For my own understanding, I am wondering the details of what changed to alter the behavior?
