'sqlConnection.InnerConnection.ServerVersionNormalized' 抛出异常（连接打开，sqldatareader 不工作）

Question

这似乎是我的计算机或 azure sql 服务器的问题。我以前遇到的问题不是问题，但是代码突然表现得很奇怪。这是我用来工作的代码。连接成功打开，我的 executenonquery 工作正常，但读者行为奇怪。

public static List<ClientDto> GetClientInformation()
        {
            List<ClientDto> results = new List<ClientDto>();
            try
            {
                using (var sqlConnection =
                new SqlConnection(ConfigurationManager.ConnectionStrings["ClientData"].ConnectionString))
                {
                    using (var command = new SqlCommand(null, sqlConnection))
                    {
                        sqlConnection.Open();
                        command.CommandType = CommandType.StoredProcedure;
                        //running the GetClientInformation stored procedure in DB
                        command.CommandText = Constants.GetClientInformation;

                        SqlDataReader reader = command.ExecuteReader();

                        while (reader.Read())
                        {
                            results.Add(new ClientDto()
                            {
                                Id = Convert.ToInt32(reader["Id"].ToString()),

                                SalesSource = reader["SalesSource"].ToString(),
                                InventoryIsActive = Convert.ToBoolean(Convert.ToInt32(reader["InventoryIsActive"])),

                                ServiceIsDelete = Convert.ToBoolean(Convert.ToInt32(reader["ServiceIsDelete"])),

                                IsActive = Convert.ToBoolean(Convert.ToInt32(reader["IsActive"])),
                                UserDefinedName = reader["UserDefinedName"].ToString()
                            });
                        }
                    }

            }
            }

sql中有数据，我的应用程序的可执行文件在我们的虚拟机（Windows Server）上运行良好。 我在代码中看到的唯一奇怪的事情是 SQLConnection 有这个内部异常（虽然它并没有停止代码运行） ServerVersionNormalized = 'sqlConnection.InnerConnection.ServerVersionNormalized' 引发了“System.NotSupportedException”类型的异常 我不确定这是否是以前的问题。

我现在正在重新安装我的 Visual Studio，看看它是否能解决问题。 对我来说，这个问题在 Visual Studio 2015 和 2017 中都发生了。

这是我的连接字符串格式： 服务器=.database.windows.net,1433;数据库=;用户 ID=;密码=;Trusted_Connection=False;加密=真；

现在看起来工作正常。对我来说，这听起来像是因为我在代码中有断点，它可能会导致问题，因为连接和运行查询之间的时间较长。
