Handling web.config files - alternative to ConfigurationManager

Question

The other day I came across an alternative way of accessing web.config configuration in some article. It allowed to:

• provide path to web.config file

• modify web.config configuration at runtime like:

  config.MySetting = "new value";

• load web.config from another web application in the same IIS (I'm not sure about it)

• work with configuration using class instance instead of static ConfigurationManager class

But that solution slipped my mind :/ I remember that the article was titled (something like this): Way of using application configuration in web applications.

Could somebody came across that solution and could refresh my memory with a link ? :)

Answer 1

Was it System.Configuration.Configuration?

Call WebConfigurationManager.OpenWebConfiguration with a file name to get a Configuration instance, which has its own AppSettings collection.
