LINQ

I am using VS2008. I have a project connect with a database and the connection string is read from App.config via ConfigurationManager. We are using L2E.

Now I added a helper project, AndeDataViewer, to have a simple UI to display data from the database for testing/verification purpose.

I don't want to create another set of Entity Data Model in the helper project. I just added all related files as a link in the new helper project.

When I compile, I got the following error:

Error   15  The name 'ConfigurationManager' does not exist in the current context   C:\workspace\SystemSoftware\SystemSoftware\src\systeminfo\RuntimeInfo.cs    24  40  AndeDataViewer

I think I may need to add another project setting/config related file's link to the helper project from the main project? There is no App.config file in the new helper project. But it looks I cannot add that file's link to the helper project. Any ideas?
