ASP site says: Unrecognized attribute 'xmlns'.

...usually in reference to some file which ends "web.config" line 2.


You might receive this error when you have multiple versions of .Net Framework.


  • Launch IIS
  • Go to the properties page for the application.
  • Select "" tab, and change the Target Framework to 2.0.
(In my case, changing it to 2.0 did nothing but render the site totally 404 -- but happily(?) I also had 4.x installed, changing to that fixed the problem.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
