The type or namespace name 'Linq' does not exist in the namespace

Question

Im trying to publish my site on an server and have been receiving this message:

The type or namespace name 'Linq' does not exist in the namespace.

Been trying to fix it now`for a while, no matter what i do, nohing is working. Ive been trying to add the following to my webconfig file:

  <compilation debug="false">
    <assemblies>
      <add assembly="System.Core, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
      <add assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
      <add assembly="System.Xml.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
      <add assembly="System.Data.DataSetExtensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
    </assemblies>
  </compilation>
  <system.codedom>
    <compilers>
      <compiler language="c#;cs;csharp" extension=".cs"              type="Microsoft.CSharp.CSharpCodeProvider,System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"              warningLevel="4">
        <providerOption name="CompilerVersion" value="v3.5"/>
        <providerOption name="WarnAsError" value="false"/>
      </compiler>
      <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb"              type="Microsoft.VisualBasic.VBCodeProvider, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"              warningLevel="4">
        <providerOption name="CompilerVersion" value="v3.5"/>
        <providerOption name="OptionInfer" value="true"/>
        <providerOption name="WarnAsError" value="false"/>
      </compiler>
    </compilers>
  </system.codedom>

Any suggestions?

Answer 1

I assume the application works locally? Seems a bit obvious but are you sure that the server you are publishing to has .net 3.5 installed?

Answer 2

How about adding System.Linq in assemblies tag?
