.net core 加密.NET Core 2中的ConnectionString部分

传统上，我会使用下面这样的

            // Open the configuration file and retrieve 
            // the connectionStrings section.
            Configuration config = ConfigurationManager.OpenExeConfiguration(exeConfigName);

            ConnectionStringsSection section = config.GetSection("connectionStrings") as ConnectionStringsSection;

            if (section.SectionInformation.IsProtected)
            {
                // Remove encryption.
                section.SectionInformation.UnprotectSection();
            }
            else
            {
                // Encrypt the section.
                section.SectionInformation.ProtectSection(
                    "DataProtectionConfigurationProvider");
            }
            // Save the current configuration.
            config.Save();

是否有一种方法可以在.NET Core 2中使用，并将ConnectionString存储在appSettings.json中
