I can’t seem to fingure out why i can’t add a reference to the .net namespace System.Linq. I used aspnet_regiis to check if i have the latest version of asp.net installed :

    C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis -lv
    2.0.50727.0    C:\Windows\Microsoft.NET\Framework64\v2.0.50727\aspnet_isapi.dll
    4.0.30319.0    C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll
    4.0.30319.0    C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll

I’ve also tried adding a reference to System.Core, but still i can’t reference the System.Linq dll.

Also in my web.config, under 

      <assemblies>
           <add assembly="System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
      </assemblies>

as iv’e mentioned before the refrences to System.Core and System.Data.Linq Exist in my website application : under Property Page -> references i could clearly see the exsiting refrences i added them again just in case and still i can’t use the
System.Linq or System.Linq.Data NameSpaces .

Any ideas how i could reference the System.Linq dll would be appreciated.

    Make sure your Project is version 3.0 or higher.

    Right Click on your project and then click add reference.

    and maybe you are looking for this: System.Data.Linq

    Check it here:

    System.Linq Namespace

    System.Data.Linq Namespace

    Best Regards
