Error Solution: Fix for ‘Unrecognized configuration section connectionStrings’ Error in ASP.NET 2.0
After publishing your website in ASP.NET 2.0 using the Build > Publish Website in the Visual Studio 2005 IDE, when you try to access your application for the first time in the browser, you may get the “Unrecognized configuration section ‘connectionStrings’” error. This is because ASP.NET has introduced the new <connectionsStrings> section in the web.config which will not be recognized in the .NET 1.1 framework.
If you look closely at the error message, IIS is trying to run the application using the 1.1 framework.
Fix the configuration section connectionStrings error.
- Open IIS and browse to the website under computer_name > Web Sites > Default Web Site > website_name.
- Where website_name is the actual name of the website, in this case the MyForecast website.
- Right click website_name. Click Properties.
- Click the ASP.NET.
- From the ASP.NET Version dropdown, select 2.0… version and Click OK.
- Now, if you visit your application main page, it should work !
(Note, you may need to restart IIS)

My Man I just can’t explain how you’ve rescued me frm this big little problem. Thanks a whole lot. I am an Application Programmer from Liberia, West Africa
Dorbor, Glad this was of help to you !
Hi.
I don’t have an ASP.Net tab!?
Please help.
Thanks.
@ Gerhardt – What is your OS and IIS version ?
I got the same error message as detailed in this post, and I set the website to ASP 2.0, and yet, when I try to open my aspx file in my browser, it says it can’t find the file…it works great on my local version of Visual Studio 2003. I am trying to run this on a Windows 2003 Server with the .Net 2.0 Framework installed.
Any ideas?
Ugh, I’m so lost. I’m trying to hack an old website together because my friend/client wanted some changes, but I have no expeirence with Visual studio/.net and am really lost.
I’ve got it working at home, but after the upload I get the connectionstrings problem you’re talking about. I don’t think I understand how to fix it though.
How do I change the IIS settings for an FTP that’s not running off this comp?

Thank you. That was very helpful. I did have to go one more step, which was to run this command:
%WINDIR%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
