Server Name Invocation with TLS

Hi

I have a .Net client programm running on Windows Server 2008. The programm communicates with a third party server using TLS. The owner of the server gives us a new requirement that the client has to use TLS with Server Name Invocation (SNI). I have checked that Winserver 2008 doesn't support SNI. 

If I migrate the server from Windows Server 2008 to Windows Server 2012 will my .Net Client support SNI?

I have checked the following link:

https://technet.microsoft.com/en-us/library/hh831771.aspx#BKMK_SNI

In the above mentioned document there is information that TLS in Win Server 2012 support SNI.

If it does not work what another solution can I use to add SNI support to my .Net 4.0 client? 

Thank you
