Hi, This is a sample from one of my project. This is recommended way. public class ConfigurationExtensions : IConfigurationExtension { private IConfiguration _configuration; public ConfigurationExtensions() { _configuration = GetConfiguration(); } public ActiveDirectoryCredentialModel ActiveDirectoryCredentials() { var activeDirectoryConfig = _configuration.GetSection( "ActiveDirectoryCredentials" ); ActiveDirectoryCredentialModel activeDirectoryCredentialModel = new ActiveDirectoryCredentialModel(); activeDirectoryCredentialModel.ServerUrl = activeDirectoryConfig[ "Server" ].ToString(); activeDirectoryCredentialModel.AdminUserName = activeDirectoryConfig[ "AdminUser" ].ToString(); activeDirectoryCredentialModel.Password = activeDirectoryConfig[ "Password" ]; return activeDirectoryCredentialModel; } private IConfiguration GetConfiguration() { var basePath = Directory.GetCurrentDirectory() + string .Format( "{0}..{0}AppWeb" , Path.DirectorySeparatorChar); var configuration = new ConfigurationBuilder() .SetBasePath(basePath) .AddJsonFile( "appsettings.json" ) .AddEnvironmentVariables() .Build(); return configuration; } public string GetKeyValue( string key) { string result = _configuration.GetSection( "appSettings" )[ "key" ].ToString(); return result; } }

i tried your code in my startup.cs private IConfiguration _configuration; public ConfigurationExtensions() { _configuration = GetConfiguration(); } public ActiveDirectoryCredentialModel ActiveDirectoryCredentials() { var activeDirectoryConfig = _configuration.GetSection("ActiveDirectoryCredentials"); ActiveDirectoryCredentialModel activeDirectoryCredentialModel = new ActiveDirectoryCredentialModel(); activeDirectoryCredentialModel.ServerUrl = activeDirectoryConfig["Server"].ToString(); activeDirectoryCredentialModel.AdminUserName = activeDirectoryConfig["AdminUser"].ToString(); activeDirectoryCredentialModel.Password = activeDirectoryConfig["Password"]; return activeDirectoryCredentialModel; } private IConfiguration GetConfiguration() { var basePath = Directory.GetCurrentDirectory() + string.Format("{0}..{0}AppWeb", Path.DirectorySeparatorChar); var configuration = new ConfigurationBuilder() .SetBasePath(basePath) .AddJsonFile("appsettings.json") .AddEnvironmentVariables() .Build(); return configuration; } public string GetKeyValue(string key) { string result = _configuration.GetSection("appSettings")["key"].ToString(); return result; } }} GETTING ERROR IN BELOW METHODS 1.Errocode-cs1520-method must have return type public ConfigurationExtensions() { _configuration = GetConfiguration(); } 2.ActiveDirectoryCredentialModel could not find the namspace.here what is ActiveDirectoryCredentialModel? public ActiveDirectoryCredentialModel ActiveDirectoryCredentials() { var activeDirectoryConfig = _configuration.GetSection("ActiveDirectoryCredentials"); ActiveDirectoryCredentialModel activeDirectoryCredentialModel = new ActiveDirectoryCredentialModel(); activeDirectoryCredentialModel.ServerUrl = activeDirectoryConfig["Server"].ToString(); activeDirectoryCredentialModel.AdminUserName = activeDirectoryConfig["AdminUser"].ToString(); activeDirectoryCredentialModel.Password = activeDirectoryConfig["Password"]; return activeDirectoryCredentialModel; }
