Assembly Erro

[pss srinivasan]

Hi I created web project in 2005 and opened in 2008 . now this error i am getting

Error 27 The type 'System.Web.Script.Services.ScriptServiceAttribute' exists in both
'c:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll'
and 'c:\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions\1.0.61025.0__31bf3856ad364e35\System.Web.Extensions.dll'

How to solve this?

Hi, take a look in your web.config. All referenced assemblies must be listed there. Remove the entry for the System.Web.Extensions.dll version 1.0.61025.0 and try again. Let me know if this helps. Regards Sebastian

It's not a bug, it's a feature! Check out my CodeProject article Permission-by-aspect. Me in Softwareland.

VS 2008 has built in support for ajax which was not present in VS 2005 that is why you are facing this error. Try this

in your Project you have referenced an Assembly with this Version 1.0.61025.0 and you opened your Project VS 2008 and Automatically it added 3.5.0.0 now you need to use one. Remove the old one that targets 2.0 <b>1.0.61025.0</b> and leave the 3.5 one. remove it in the webconfig.
