In the event you want to change these defaults, you just need to specifiy the overriden values. The configuration specified in the file is merged with the default in code. As with the Microsoft standard, providers added in the providers element are merged with the defaults. To completely replace the defaults, add the <clear /> element as the first element in the providers collection.
