5.1.0-preview1.22279.3

[Preview Release 5.1.0-preview1.22279.3] - 2022-10-19

This update brings the below changes over the stable release v5.0.0:

Fixed

Converted ExecuteNonQueryAsync to use async context object. #1692
Code health improvements #1604 #1598 #1595 #1443

Known issues

When using Encrypt=Strict with TLS v1.3, the TLS handshake occurs twice on initial connection on .NET Framework due to a timeout during the TLS handshake and a retry helper re-establishes the connection; however, on .NET Core, it will throw a System.ComponentModel.Win32Exception (258): The wait operation timed out. and is being investigated. If you're using Microsoft.Data.SqlClient with .NET Core on Windows 11, you will need to enable the managed SNI on Windows context switch using following statement AppContext.SetSwitch("Switch.Microsoft.Data.SqlClient.UseManagedNetworkingOnWindows", true); to use TLS v1.3 or disabling TLS 1.3 from the registry by assigning 0 to the following HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.3\Client\Enabled registry key and it'll use TLS v1.2 for the connection. This will be fixed in a future release.
