The IIS 7 configuration hierarchy works like this:

  1. Framework OR Framework64 Machine.config
  2. Framework OR Framework64 ASP.net Web.config
  3. System32\Inetsrv\Config\ApplicationHost.config
  4. Your Website\web.config Your
  5. Website\Appdir\web.config

The first two depend on the bitness of your application pool - the 64 version is the "root" of 64-bit app pool configuration.

Applicationhost.config contains entries applicable to either bitness32 or bitness64 using preConditions, so it's cross-bitness. Web.config files at lower levels in your site or content folders can also use preconditions.

If you want to apply a setting to a particular application, you apply it at the level closest to that application. If you want to apply it to everything on the box, you edit the Framework folder settings (which is generally a bad practice as it breaks xcopy deployability as a unit, but is sometimes unavoidable).

Does that answer your question?

  • The IIS GUI edits the web.config it thinks it needs to edit - all IIS settings are stored either in Applicationhost.config or web.config in your site's directories. So if you can set what you need to set through the GUI, you can just use that, and it should just work? What do you need to set?

  • Where does the CLRConfigFile element fit into this hierarchy? Does it? msdn.microsoft.com/en-us/library/aa347554(v=VS.90).aspx Apr 20, 2011 at 16:55
  • at around the applicationhost level, I'd guess - ballpark of site web.config (4).
