C# Samples and TLS 1.2 #39
Description
It looks like on May 31st BP will be ending support for TLS 1.0 and 1.1. And I see that the C# sample project is using .Net 4.5. By default .Net 4.5 uses a TLS version prior to 1.2. I suggest upgrading the project to .Net 4.6 (this uses TLS 1.2 by default) or manually setting the SecurityProtocol to TLS 1.2 prior to making the connection in "PerformPost" in BluePay.cs. The exact code would look somthing like ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12.
Thank you, and thank you for keeping the samples up to date with the documentation.
