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;
}

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;
        }
    }
