Migration+Errors

You might come across this error when running an ASP.NET 2.0 on IIS 7.0 or 7.5:


 * There is a duplicate 'system.web.extensions/scripting/scriptResourceHandler' section defined.** Screenshot [|duplicateweb.jpg]

Solution:
Run the app in its own app pool targeting 2.0. To do this:
 * 1) Start Inetmgr.exe
 * 2) Goto Web Site and Advanced Settings
 * 3) Change Application Pool from ASP.NET 4.0 to 2.0

Workaround:

 * Remove system.web.extensions from application level web.config. They are usually found at the top of the application level web.config
