Telerik Report Viewer on ASP.NET WEB FORM (aspx page)

[Swei]

I'm trying to display a Telerik Report Viewer on ASP.NET WEB FORM (aspx page) and keep getting this error.

My Newtonsoft.Json is the latest version 11.

Please help.

I'm no expert at this but I think you have to change the version number in your web.config file. Mine looks like this.

<dependentAssembly>
        <assemblyIdentity name="Newtonsoft.Json" publicKeyToken="30ad5fe6b2a6eeda" culture="neutral" />
        <bindingRedirect oldVersion="0.0.0.0-7.0.0.0" newVersion="7.0.0.0" />
      </dependentAssembly>

You need to change the Version number to whatever version you are using.
