V5.8
We have taken an important decision to not enforce TLS1.2 protocol in our .Net SDK as it applies the setting on the whole app domain(Issue #54 ). Instead we are delegating the setting for TLS1.2 to be applied by client apps if they see any issues in connecting with QBO V3 API. Please note that we only support TLS1.2.
If you cannot connect to QBO V3 API using this SDK for any reason after upgrading to 5.8.0, then please add this line of code in your apps right before you build your ServiceContext object-
ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12
