cannot use secure map service

HuyHo

We have a secure tiled map service that we wish to consume in ArcGIS Runtime 10.2.7.  But when we run it, we get the following error:

Layer could not be added to Map because layer initialization failed. See InnerException for more information.

InnerException: The request was aborted: Could not create SSL/TLS secure channel.

I open the same map service using ArcGIS Online, ArcMap, JavaScript, and Quartz Runtime, they all work.  Is there something I am missing?

There seems to be some issues with the SSL certification or validation of it. See this SO thread with some good tips how to handle it: c# - The request was aborted: Could not create SSL/TLS secure channel - Stack Overflow
