After update to 12.9.5 Unable to Connect to Data Source

After update to 12.9.5 Unable to Connect to Data Source

We connect using two different methods, VPN and Terminal Server (RDS)

The update went well through VPN, updated the DB and still runs fine.
After installing on the terminal server we are getting this error when trying to connect.

Method not found: 'Void System.Data.SqlClient.SqlConnectionStringBuilder.se_Authentication(System.Data.SqlCient.SqlAuthenticationMethod)'



Thanks,
Rob

Hi,
It seems to be a problem with .NET Framework. Could you verify what version is installed and make sure that .NET 4.6 is installed?
