My one of the applications is built on VB .NET 4.0 but the Application & Database Servers contains .NET framework 4.7.2.

I need to upgrade my application to support TLS1.2 from SSL.

As per the link TLS 1.2 in .NET Framework 4.0, do I need to add the below code in Global.asax file or not? as my application built on .NET 4.0.

ServicePointManager.SecurityProtocol = DirectCast(3072, SecurityProtocolType)

If I have to add the code, then do I need to change anything in the DB server (currently accepts SSL requests) to accept this TLS12 request? and if my application use SOAP call (WCF), then do I need to add the above code in the WCF application as well?

  • The above code worked for me in VB.Net (keeping the project in framework 4.0). Also seem to need the line `ServicePointManager.Expect100Continue = True` – ConfusionTowers Mar 22 '19 at 16:48

See official TLS 1.2 guidance: https://learn.microsoft.com/en-us/dotnet/framework/network-programming/tls

It would be best to retarget (rebuild) your app against higher .NET Framework.
