根文件夹中是否可以有多个Web.Config文件

Question

We can configure the settings for the webpages in a particular folder by keeping single web.config. Can there be multiple web.config in a same hierarchy as i saw some where web.config.debug and web.config.release and web.config . Why they are intended for.

Answer 1

Those are web.config transformations , which allow you to apply changes to different builds of your project (debug, dev, release, etc).

The ones suffixed with .debug , .release , etc, are the transformation files. They take the base web.config and modify it using the XML-Document-Transform attributes you specify.

A classic use case is the debug=true attribute, which you never want to use in production. You can use a simple transformation to remove it in your web.config.release file:

Web.config

<configuration>
    <compilation debug="true" />
</configuration>

Web.config.release

<configuration>
    <compilation xdt:Transform="RemoveAttributes(debug)" />
</configuration>
