is the dll in the BIN folder? Add an app.config to that folder and add your key.

Did you check solutions below. You need to put it in web.config.

If it is a web application, then you need to put the key in the web.config (under AppSettings) node.
All the class libraries used in web application will have access to web.config keys.

For ConfigurationManager, you will need to add a reference manually and also add a namespace

C#

using System.Configuration;

Hope that helps

You must put the AppSettings value inside the web.config of the application, because it override the app.config from the class library.

Add a reference to System.Configuration namespace in the class library project, them get the value you're expecting from the web.config file, not from the app.config file.
