ConfigurationManager.AppSettings returning null

I am using ConfigurationManager.AppSettings["smtpHost"] to read a value from the app.config file in my business logic layer, but the value returned is always null, even though the key exists and it has a value, Does any one know why?

App.config file in BLL:

<appSettings>
  <add key="smtpHost" value="smtp.gmail.com" />
</appSettings>

I added the same thing to the web.config file.

And I try to get;

var host = ConfigurationManager.AppSettings["smtpHost"];

I found the problem.

I defined it in the web.config file in the UI layer.But I called in the unit test method of the Business layer. It worked correctly when called from the UI layer

Your code is correct (i have tested), you need to make sure that your app.config file is in your main project (exe).
