Changes in App.config do not reflect after restarting the application

Question

I use the app.config file to store the dynamic parameters of my application. The problem is that when I change the value in the app.config file and run the application, it does not load the new value from the configuration file. It looks like the values ​​in the app.config file are only read and inserted into the exe file at compile time!

This is how I read the configuration file:

public class Helper
{
    static Helper()
    {
        Foo = ConfigurationManager.AppSettings["Foo"];
    }
    public static string Foo { get; set; }
}

Did I miss something?
