Server Name Invocation with TLS RRS feed

  • Question

  • 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:

    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

  • Hi ProgArch Krakow

    1. Server side, you should use 2012 or above or maybe some third party servers like apache might support it. 
    2. Client side. As far as I know, .Net 4.0 Framework don't have any build-in class library or method support SNI. You have to implement on your own logic with the SNI protocol.
    3. Please check support and not support list in Wikipedia.

    By the way, after do some search, I found someone already raise the request to add the SNI support in visual studio connect, and maybe the function could be added into .net in the future.
