Question

我尝试在DNX Core上的Ubuntu linux下运行EF7

我写了简单的控制台应用程序。它运行。它运行良好但是当我连接到我的SQLServer或Azure SQL Server时出现此错误

如果我在Google上搜索此错误，则会向我展示有关SQLServer设置的手册。但我尝试在azure上运行此代码并获得相同的结果。我的连接字符串是

Server=tcp:{AzureSQLServer}.database.windows.net,1433;Database=students;User ID={user};Password={password};Trusted_Connection=False;Encrypt=True;Connection Timeout=30;

Linux下的EF7（CoreCLR）+ MSSQL =加密（ssl / tls）握手失败
