.NET and TLS

Published by xavier on January 20, 2022
  • Before .NET 4.6 – TLS 1.1 is default and negotiations start down
  • .NET 4.6 – TLS 1.2 is default and negotiations start down
  • .NET 4.7 – the default value of this property is SecurityProtocolType.SystemDefault. This allows .NET Framework networking APIs based on SslStream (such as FTP, HTTP, and SMTP) to inherit the default security protocols from the operating system or from any custom configurations performed by a system administrator.
