Windows service installer not reading App.Config file

Question

I have added App.Config in my project. I have a installer class(ProjectInstaller.cs) which needs to read values from App.config. I am providing the keys . Below is the sample Code :

ConfigurationManager.AppSettings["CONFIG_FILE"]

I am getting null values as per above code ,when invoked in Installer class. But in App.Config file the value for the above key exists.

Try:

public string GetServiceNameAppConfig(string serviceName)
{
    var config = ConfigurationManager.OpenExeConfiguration(Assembly.GetAssembly(typeof(MyServiceInstaller)).Location);
    return config.AppSettings.Settings[serviceName].Value;
}
