theBody.Append("Session Values: " + "
");
foreach (string s in Session.Keys)
theBody.Append(s + ":" + Session[s] + "
");

We are working on a web application and the target deployment includes Windows 2003 64-bit. When we run the application on the 64-bit OS, it gives the following error:
The entry 'asp:System.Web.UI:System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' has already been added
The web.config file includes the following:
<pages validateRequest="false" enableEventValidation="false" viewStateEncryptionMode="Never" theme="esl_theme">
<controls>
<add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>
</controls>
</pages>
And if we remove the line <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>, it seems to work.
Can somebody understand the problem and take corrective action? The application does not compile on 32-bit OS without this.
