I have a Webapp which was developed for framework v2.0/lower, it
references System.Web.Extentions 1.0.61025.0
I installed .net 3.5 on that box and the working webapp starts failing
with the below error:
error CS0433: The type
'System.Web.Script.Services.ScriptMethodAttribute' exists in both 'c:
\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions
\1.0.61025.0__31bf3856ad364e35\System.Web.Extensions.dll' and 'c:
\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions
\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll'

There is no where System.Web.Extensions 3.5 is referenced but the
runtime compiler seems to be it picking up. I also removed assembly
redirect specified for System.Web.Extensions from machine.config but
it dint make a difference.


Any idea where is my webapp referencing the 3.5 version from?

You should have checked google for the error code, which would have brought
up, e.g,
http://forums.asp.net/t/980517.aspx

Also, you might want to make sure that the web site running the application
is using the 1.1 framework. Installing the 3.5 framework might have changed
it.
 
Thanks Andrew...I checked that... I kinda know why I get into the
problem. In the web.config of my webapp, I have just referenced 1.0
version of extensions. I have also removed any reference to 3.5
version of extensions in machine.config but still my web while
compiling in runtime references
I wana figure out from where the compiler is adding the reference to
3.5.
Configuration files checked for no reference to 3.5 dll:
webapp web.config
global web.config
machine.config


c:\windows\system32\inetsrv> "C:\WINDOWS\Microsoft.NET\Framework
\v3.5\csc.exe" /t:library /utf8output /R:"C:\WINDOWS\assembly\GAC_MSIL
\Microsoft.Practices.EnterpriseLibrary.Common\3.1.0.0__1809b656db4db36f

\WINDOWS\assembly\GAC_MSIL\System.Web.Extensions
\3.5.0.0__31bf3856ad364e35\System.Web.Extensions.dll"
 
I found the problem. There was a web.config in c:\inetpub\wwwroot
which had references to system.web.extensions 3.5 dll
Removing the reference from wwwroot web.config made my old app work...
