issue with ajax version

When I try to run Umbraco I get error

Could not load file or assembly 'System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

The version of System.Web.Extensions on my PC is newer - 3.5.0.0 (installed in GAC)

What is the recommended solution?

Thanks for advice

I'd try adding this into your web.config

    <runtime>
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31BF3856AD364E35" culture="neutral" />
        <bindingRedirect oldVersion="1.0.61025.0" newVersion="3.5.0.0"/>
        </dependentAssembly>
      </assemblyBinding>
    </runtime>

Hi Vaclav

Could you please try to install ASP.NET AJAX 1.0: http://www.microsoft.com/downloads/details.aspx?FamilyID=ca9d90fa-e8c9-42e3-aa19-08e2c027f5d6&displaylang=en

I have had this error earlier, and I think that I solved it by the above installation.

I tried to change the references in web.config to point to my version, but the old version is still referenced from the binaries.

I do not know how to rebuild the binaries, there is no VS project included.

Thanks

Vaclav, did you try to download the file that i linked to, and install the .NET AJAX extension from the downloaded .msi-file?

Vaclav,

The binding redirect may require the older versions to be present so you may have to install the older version as Kim suggests. You can try a more generic version of the redirect first to see if that fixes it:

    <runtime>
      <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
        <dependentAssembly>
        <assemblyIdentity name="System.Web.Extensions" publicKeyToken="31BF3856AD364E35" culture="neutral" />
        <bindingRedirect oldVersion="1.0.0.0-1.1.0.0" newVersion="3.5.0.0"/>
        </dependentAssembly>
      </assemblyBinding>
      <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>

If that doesn't work then installing the older version should work for you as Kim suggests. I would still keep the redirects in your web.config to avoid conflicts with different versions of the AJAX assemblies.
