c# - How do I create a Web Service Reference to a TLS 1.2 WebService? -
we received message utah tax authority upgrading web service tls 1.2.
when tried create web service reference in visual studio 2010 got exception "could not establish secure channel ssl/tls authority 'tap.tax.utah.gov'.”
the address is: https://tapstaging.tax.utah.gov/efile/mfet/wsdl/
there not seem anyplace set protocol use when creating web reference.
okay, got it. @ least able 'create' web service. rebooted machine , added registry key hkey_local_machine\software\wow6432node\microsoft.netframework\v4.0.30319 node , seemed work.
i forced use x86 platform due company using very, old database drivers may have been solution or reboot, either way feel little bit less helpless.
here registry keys linked page:
[hkey_local_machine\software\microsoft.netframework\v4.0.30319] "schusestrongcrypto"=dword:00000001
[hkey_local_machine\software\wow6432node\microsoft.netframework\v4.0.30319] "schusestrongcrypto"=dword:00000001
