There is a bunch of current web references in my WPF application that were generated using the "add web reference" option in Visual Studio. However I am trying to enforce https on callings these web services using TLS1.2 (already done work on server
side). I have done all the cert imports and I can access the WSDL over https fine on the web browsers. Application works if I enable tls1.0 on the server side, but when I disable I just get the error occurred on send "An existing connection was forcibly
closed by the remote host". Is there a setting I have to set in the app.config to enforce tls1.2?
It was 4.5.2. As DA924x suggested I am continuing discussion here instead https://forums.asp.net/p/2146604/6228725.aspx?p=True&t=636719049174795534. I changed the target framework to 4.7 but am now having issues with FIPS compliance
