Hi,

.Net Framework installed on my computer is 3.5, but i made a project still built in 2.0.

Now, in all aspx pages of that project, the first line is underlined in VWD with a green line and this message:

<%@ Page Language="VB" ValidateRequest="false" Debug="true" AutoEventWireup="false" CodeFile="wijzig2.aspx.vb" Inherits="wijzig2" %>

"Namespace or type specified in the Imports "System.Linq" doesn't contain any public member or can't be found"

All the pages in the project contain different inherits="...".

The pages run normally, but why this warning?

Thanks

 You must have a reference to system.linq somewhere which only exists in 3.0 and above.

It could be in your web.config, or in the top of your .aspx file or in the top of your aspx.vb file or in your masterpage file.

 Yes , Use vwd search utility to find the location the used "System.Linq" namespace ,

So inside VWD , hit ( CTRL + F ) and select to search in the whole website .

Thanks both

Linq only works with 3.5 projects. You can add a reference to it without upgrading the project, but your code will effectively become dependent on .NET 3.5
