SharePoint Feature for .NET 3.5 Web.config Changes
Leading on from this post, and this post, I created a SharePoint Solution/Feature combo to update Web Application web.config files with the changes neccesary to support;
The Web.config changes don’t require that you have Ajax and MSChart installed on your WFE’s so you can deploy the solution even if you don’t need the Ajax/MSChart stuff.
Alternativly you can modify the Visual Studio/WSPBuilder solution and change it yourself to remove those bits.
Download the Visual Studio/WSPBuilder solution here, or download just the SharePoint WSP here.
