I have a project originally developed in VS2010 .NET 4. I need to upgrade it to use TLS 1.2 so I have copied it to my Windows 10 machine running VS1013. I set the framework to 4.5.2 and recompile with no issues.
When I try to Update the Service Reference, I receive the “Could not create SSL/TLS secure channel” error. I am able to see the wsdl contents in a browser and I have installed the certificate under Trusted Authority.
If I try to add a New Service Reference in this, and a different project, I get the same error message.
I read this question “Could not create SSL/TLS secure channel” when adding service reference on WIndows 10 but that did not solve the problem though I have not restarted my machine as the answer said I didn't need to.
I am stuck trying to figure out where the actual issue lies.
TLS 1.2 is enabled in IE Internet Settings.
Thank you
