And to disable Umbraco web configuration inheritance move system.web, system.web.extensions, applicationSettings and system.webServer nodes into location node with inheritInChildApplications attribute:
Btw, location trick can be useful in many other situations. Unfortunately it can’t solve inheritance problem with configSections node.
