Parser Error Message: Unrecognized attribute 'type'

Yes: I'm having a bit of a geekend this week. I decided to build out a dev box in a VPC of a Windows 2003 Server with the ASP.NET AJAX libraries and futures.

For fun ;)

Upon setting up the ASP.NET AJAX documentation, I got the most helpful Parser Error Message:

Unrecognized attribute 'type'.

.. followed by specifics relating to the web.config file for the site.

Fortunately, this is trivial: by default, Windows 2003 Server configures ASP.NET 1.1 instead of ASP.NET 2.0 as the default version, and you get the error running a 2.0 site atop a 1.1 verwsion.

Changing to 2.0 solved the problem; here are the steps:

Open IIS
Right-click on the default web site and click 'properties'.
Click on the ASP.NET tab.
Select ASP.NET 2.0 as the default version.

Re-render the page and the error should go away.

~ the most helpful Parser Error Message: unrecognized attribute 'type'. ~

I totally agree. The Parser Error Message should be smarter to tell the right problem area.

This short article is really useful to me. Thanks!

Thanks for posting that! I just ran into the problem, and this was the first page that came up for my google search. I thought it would take up much more of my time to fix the error. Instead it took all of 2 minutes. :-) Thanks!!

What if there is no ASP.NET tab? I reinstalled .NET 2.0 and .NET 3.0, but still no .NET tab in the properties. .NET 1.1 and 2.0 are both allowed extensions.

This was an easy fix and EXTREMELY helpful. I ran into this issue earlier this year and was able to fix it with MUCH effort. This was the fast and easy answer.

Thanks!

# re: Parser Error Message: Unrecognized attribute 'type' 5/16/2008 1:07 PM Killjoy

This should win advice of the year. So many guides talk about publishing asp.net website, yet none mention, this blatantly needed information.

The rest should hang their heads in shame.

I don't have control over IIS box and can't upgrade .net to newer version. So this solution does not work in this case

# re: Parser Error Message: Unrecognized attribute 'type' 12/12/2008 1:00 PM Jeff

Aspnet framework version is greyed out and
the list is diasabled. It says 1.x but I see
that higher versions are installed. Why can't I change it?

# re: Parser Error Message: Unrecognized attribute 'type' 12/13/2008 10:31 AM Jeff

I noticed that Framework 1 was not installed

# re: Parser Error Message: Unrecognized attribute 'type' 1/7/2009 11:40 AM Susan C
