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
