Multiple assemblies of System.Web.Extensions in one project?

Question

I am having problems moving a website from one server to another. It seems that the problem is related to downloading multiple versions of System.Web.Extensions. In most cases, the code uses version 3.5, but a third-party control requires version 1.0.6. I did not think it was possible, but it seems to work in this situation.

Is there a way to use the System.Web.Extensions version for the GAC site, but import version 1.0.6 DLLs only for these controls?

You tried to put the assemblyBinding tag in your configuration file like this:

 <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>
    </assemblyBinding>
  </runtime>
