Troubles with Telerik Reporting 2010 Q2 and Framework 4.0

[Edgar]

Hi,

I upgrade recently my web application thah used Telerik Reporting 2009 Q2 with II 6.0 + Framework 3.5 to Telerik Reporting 2010 Q2 with IIS 7.0 + Framework 4.0
 
I deployed my web application using Telerik Reporting 2010 Q2 and IIS 6.0 + Framework 4.0 and gets a error, over Visual Studio 2010 the reports display it correctly but over IIS display the following error:

Message:

Exception of type 'System.Web.HttpUnhandledException' was thrown.

Inner Exception:

The type initializer for 'Telerik.ReportViewer.WebForms.AjaxHelper' threw an exception.
  Thanks in advance,
Edgar.

Hi Edgar,

Please add the following section in your web.config file and try again:

Copy Code

<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>

The web ReportViewer needs the System.Web.Extensions assembly for the Ajax support, so in this line of thoughts if the first approach does not help, please try to install the ASP.NET Ajax Extensions from this link.

All the best,
Steve

Thanks a lot Steve!

In my case newVersion="4.0.0.0" works for me. Because I'm using Framework 4.0.

My issue was resolved.

Best regards.
