c# System.Data.SqlClient.SqlException: Snix_Connect in macOS

问题

I am writing an asp.net 5 app with ef 7 to work with sql server. It's all okay when the app is running under windows. When I tried running it under macOS and when i need to interact with the database the following exception appeared:

Unhandled Exception: System.Data.SqlClient.SqlException (0x80131904): Snix_Connect (provider: SNI_PN7, error: 25 - SNI_ERROR_25) Snix_Connect (provider: SNI_PN7, error: 25 - SNI_ERROR_25) --->
