Script Manager exists in both GACs!

[Roger]

Hi - just downloaded Telerik controls and now I can't get any of my websites to compile.  I am using VWD Express 2008 and getting messages like

Error    18    The type 'System.Web.UI.ScriptManager' 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'   
c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\_salesraw\3f1a6d98\c087e20c\App_Web_uqevys61.0.cs    202   

I'm really stuck - any help greatly appreciated.

Hello Roger,

The error message indicates that the VWD Express 2008 system detect both 1.0 and 3.5 version of the AJAX extension framework. Actually, AJAX extension framework is the core framework (contains the base classes of AJAX system). You can review the following forum:

It was too simple man, I found it

add the fol. lines in web.config before the end tag </configuration>

<runtime>
<assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
<dependentAssembly>
<assemblyIdentity name="System.Web.Extensions" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/></dependentAssembly>
<dependentAssembly>
<assemblyIdentity name="System.Web.Extensions.Design" publicKeyToken="31bf3856ad364e35"/>
<bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
</dependentAssembly>
</assemblyBinding>
</runtime>

it works fine

Right click on your solution.

Open Property Pages.

In References remove System.Web.extensions 3.5 version.

Happy coding....(y)
