Reloading configuration without restarting application using ConfigurationManager.RefreshSection

Question

Has anyone got this working in a web application?

No matter what I do it seems that my appSettings section (redirected from web.config using appSettings file=".\Site\site.config") does not get reloaded.

Am I doomed to the case of having to just restart the application? I was hoping this method would lead me to a more performant solution.

Update:

By 'reloading' I mean refreshing ConfigurationManager.AppSettings without having to completely restart my ASP.NET application and having to incur the usual startup latency.

Make sure you are passing the correct case sensitive value to RefreshSection, i.e.

ConfigurationManager.RefreshSection("appSettings");
