Solution 1

Most likely, you have a reference to the assembly System, but you also need to reference the assembly System.Core, where System.Link.* types are defined. This is the part of .NET FCL and can be found in the GAC. So, you can do it using the tab .NET of the window "Add Reference".

Please see: http://msdn.microsoft.com/en-us/library/system.linq.aspx[^].

I already did. Check it up again. If in doubt, look at the node "References" of your project. Does it contain System.Core?

XML

I hope this code help you fixed the problem, just in case you did not add this line into web config where other assembly's are

<add assembly="System.Data.Linq, Version=3.5.0.0, Culture=neutral, PublicKeyToken=B77A5C561934E089"/>
