Microsoft.Web.Extensions dll are related to AJAX. There were changes and upgrade.

There are two options:
1. Either open the old project again in VS2010 and let the VS upgrade it by itself OR
2. Create a new dummy website, copy the Web.Config default content and replace it with your current application Web.Config. Add any extra config data if got replaced like connectionstring, etc.

All you need is to make the Web.Config file as per VS2010.

Will this resolve the error? I doubt that. Web.Config still has a reference entry that is incorrect. Your said new reference will add things not modify!
