ConfigurationManager doesn't save settings
Here is the code I'm using: private void SaveConfiguration() { if (txtUsername.Text != "" && txtPassword.Text != "") { ConfigurationManager.AppSettings["Username"] = txtUsername.Text; ConfigurationManager.AppSettings["Password"] = txtPassword.Text; MessageBox.Show("Su configuracion guardo exitosamente.", "Exito!"); this.Close(); } else { MessageBox.Show("Por favor lleno los campos.", "Error."); } } Now, the settings are persisted but when I close the application and press F5 to run it again, the values are reverted to what is typed into the app.config file. Any suggestions? il_guru I think you
