Before upgrading to .NET Data Provider for Teradata version 17.10, please note this release includes three versions of the Teradata.Client.Provider assembly for:

• .NET Framework 4.6.1
• .NET Standard 2.0
• .NET 6

The following features are not available when using .NET Standard, .NET Core, or .NET 6:

• Configuration Files
• Performance Counters
• Entity Provider

Now requires .NET Framework 4.6.1 or higher

If your application requires a lower version of the .NET Framework, you will need to use an older version of the .NET Data Provider for Teradata.

Support for Visual Studio 2012 has been dropped

If you still develop your applications using Visual Studio 2012 or earlier, you will need to use an older version of the .NET Data Provider for Teradata.

Slower connection establishment if Transport Layer Security (TLS) is not available

The Data Provider supports Transport Layer Security (TLS) for establishing connections. By default, the Data Provider will try to establish TLS connections to the Advanced SQL Engine. If the SQL Engine does not support or is not configured to accept TLS connections, the Data Provider will take approximately 240ms longer to establish the connection. See Security Features for more details.
