Hello, I am currently working on a project for my degree using

asp.net, C# and Sql. The problem I am having is with my connection.cs

file that I have created, the code I have is as follows:

using System;
using System.Configuration;
using System.Linq;
using System.Data.Linq;
using System.Xml;
using School.SchoolCore.Core.Domain;
using School.SchoolCore.Properties;
using StructureMap;

namespace School.SchoolCore.Core.DataAccess.Impl
{
    public class Connection
    {
        public SchoolDataContext GetContext()
        {
            string connString = "";
            try
            {
                XmlDocument doc = new XmlDocument();
                doc.Load("ConnectionStringToUse.xml");

                XmlNodeList xnl = doc.GetElementsByTagName("environment");
                XmlElement xe = (XmlElement) xnl[0];

                switch (xe.InnerText.ToString().ToLower())
                {
                    case "local":
                        connString = Settings.Default.SchoolConnectionStringLocal;
                        break;

                    case "development":
                        connString = Settings.Default.SchoolConnectionStringDevelopment;
                        break;

                    case "production":
                        connString = Settings.Default.SchoolConnectionStringProduction;
                        break;

                    default:
                        throw new Exception("No connection string defined in app.config!");
                }
            }
            catch
            {
                connString = Settings.Default.SchoolConnectionStringLocal;
            }

            SchoolDataContext fdc = new SchoolDataContext(connString);
            return fdc;
        }
    }
}

I think the problem is that the using directives are not all being used as they should. I have resharper on visual studio and it is saying that these three directives:

using System.Configuration;
using System.Linq;
using System.Data.Linq;

are not required and can be removed from code. however I think because it is not actually using.sytem.linq it is not recognising my connString.

I'm relativly new to asp.net and C# so apologise if this all sounds like gobble d goop.

I would really appreciate any help offered.

many thanks

however I think because it is not actually using.sytem.linq it is not recognising my connString.

Did you do some tests to verify whether it's recognizing your connString?

Cheers,

The problem actually appears to be that Visual Studio is not recognising one of my assembly references
