📝 IIS7 Deployment: Duplicate 'system.web.extensions/scripting/scriptResourceHandler' Section

So you're trying to deploy a .NET 3.5 website on the default app pool in IIS7, but you're encountering an error that says, "There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined." Commenting off the offending lines didn't help either. Don't worry, I've got you covered! 🤓

Understanding the Issue

The error message indicates that there are multiple configurations of the 'system.web.extensions/scripting/scriptResourceHandler' section defined in your web.config file. This usually happens when you have duplicate entries or conflicting configurations.

Easy Solutions

Here are a few easy solutions to fix this issue:

1. Check the web.config File: Open your web.config file and search for the 'system.web.extensions/scripting/scriptResourceHandler' section. Ensure that there is only one instance of this section present. If you find duplicates, remove the extra entries.

2. Remove Conflicting Configuration: It's possible that another section in your web.config is conflicting with the 'system.web.extensions/scripting/scriptResourceHandler' section. Look for any other sections that might mention or affect script resources and remove any conflicting configurations. Be cautious not to remove any necessary settings for other functionality.

3. Upgrade the .NET Framework: If your website requires .NET 4.0, consider upgrading your website to .NET 4.0 or later. This will ensure that the 'system.web.extensions/scripting/scriptResourceHandler' section is compatible with your application's requirements.
