I need to disable TSL 1.0 on my web server and use TSL 1.2 instead for PCI compliance, the following changes were made to the Global.asax.cs file.
protected void Application_Start()
{
//most of API providers require TLS 1.2 nowadays
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
I have also updated the framework to 4.6, this works ok, but when I disable the TSL 1.0 using IISCrypto on the web server, the web application errors, can anybody help me resolve this.
Many thanks,
Paul.
