Getting error while authenticating salesforce login in c#
I am using soap api for salesforce login authentication in c# but getting below error.
UNSUPPORTED_CLIENT: TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https.
So I have already deactivated "Critical Updates" in salesforce but still getting same error.

Salesforce is requiring an upgrade to TLS 1.1 or higher by July 22, 2017 in order to align with industry best practices for security and data integrity.
So better have it enabled now. Because in near future you have to do it somehow.
You have to enable SSL and TLS 1.1 in your app/server.
