Accessing WCF service running on the server with TLS 1.2 only enabled

We have a WCF service running on Windows server with TLS 1.0 and 1.1 disabled. Is it possible to connect to this service from Windows 7 client without TLS 1.2.

Solution

  • Windows 7 does support TLS 1.2. However, you MUST use .NET 4.5 or above to use TLS 1.2.

    Sources: S/O - Are there .NET implementation of TLS 1.2?
