Web.config Validator

What can it do?

Identifying why a web.config file isn't working, can be a hard and challenging task. We wrote this validator purely out of frustration after years of looking through Yellow Screens of Death. Common tasks like setting up custom errors, doing XDT transformations, or adding connection strings are so much more fun with a little help from the web.config validator. By pasting the content of your web.config file, we check for valid XML, correct ELMAH configuration, conformance with the configuration XML schema, and much more.
