ReadAsync throws open SSL error for specific table on Linux on Azure

See original GitHub issue

Describe the bug

When connecting to SQL Server on Azure with Linux client we get a SQLException that has a error linked to OpenSSL. We tried both Ubuntu 18x and Ubuntu 19x and same error.

Oddly enough, this error happens on a very specific table. Also same error with older client System.Data.SqlClient This is on net core preview 7

Exception message:
Stack trace:
 ---> System.Data.SqlClient.SqlException (0x80131904): A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 35 - An internal exception was caught)
 ---> System.IO.IOException: The decryption operation failed, see inner exception.
 ---> Interop+OpenSsl+SslException: Decrypt failed with OpenSSL error - SSL_ERROR_SSL.

--- End of stack trace from previous location where exception was thrown ---
   at Apption.DBConnectors.SQLServer.SQLServerTableMetadata.ReadTable(SQLDatabase database, SQLTable table, ITargetBlock`1 target)

Expected behavior

SQL Clients reads data correctly from source data.

Further technical details

Microsoft.Data.SqlClient version: 1.0.19189.1 SQL Server version: Azure SQL Server Operating system: Ubuntu 18.04 docker container

Additional context Error seems to be related to SSL version https://stackoverflow.com/questions/29627991/1408f10bssl-routinesssl3-get-recordwrong-version-number-call-on-indy

Well I’m sorry I broke it in the first place. It’s been a bad day for my quality of my work.

Sorry for my impatience to get this fix out in a hurry, but I really believe that it is urgent now where ef core relies on M.D.SqlClient. It’s release is imminent and it will have a dependency with this fatal issue. I really hope that a patch release will be out asap.

I created https://github.com/aspnet/EntityFrameworkCore/issues/17592 to track the update of the reference if this gets a patch release before the ef core release
