Description
Currently in SslTransport.cs it is hard coded to use 'SslProtocols.Default' which points to TLS 1.0 only (see API).
There should be a way to force the usage of newer version of TSL > 1.0 in environments which do support this (.Net 4.5).
Solution:
A patch is needed setting the value while keeping the current setting as the default. The patch should provide a means of mapping a URI option to the appropriate enum value keeping in mind that the 1.1 and 1.2 TLS entries are only valid on .NET 4.5+
