Seeing the same issue as Brady. When trying to hit a test WebAPI I have sitting on Azure I get the following stack trace:
Microsoft.SPOT.Net.Security.SslStream::Authenticate
Microsoft.SPOT.Net.Security.SslStream::AuthenticateAsClient
System.Net.HttpWebRequest::EstablishConnection
System.Net.HttpWebRequest::SubmitRequest
System.Net.HttpWebRequest::GetResponse
NetduinoSensorBaseStation.Program::Main
When I hit an API without SSL all is right in the world. Non ssl -> http://jsonplacehold...ode.com/posts/1
Chris DM me for the Azure address if you'd like to test against it.
