Can't access a class developed outside of native namespace

OK, I've looked at this much too long and am only breaking it further.  I have a class I generated outside of my solution namespace.  I've add its project to my solution, I've add the reference .dll for the class as well.  I cannot "get" to the methods or properties defined within the class.  They are declared public, not sure what to do.........:

Class code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Windows.Forms;

//using System.Text.Encoding;

namespace Keithley2701ClassLib
    //class General

    public static class General

        // Version 1.1
        // EEB
        public const Int16 port = 1394;

        public static System.Net.Sockets.TcpClient KI2701Client = new System.Net.Sockets.TcpClient();

        public static System.Net.Sockets.NetworkStream KI2701Stream;

        public static string KIstatus;

        public static bool connected = false;

        public static string ip = "";

        public static byte[] KIByte;

        public static string KIData;

        public static bool front = false;

        private static bool dis = false;

        public static void send(string KIData)
            KI2701Stream = KI2701Client.GetStream();
            KIData = (KIData + "\r");
            //  Add control reset to the command line
            KIByte = System.Text.ASCIIEncoding.ASCII.GetBytes(KIData);
            //  Convert to byte
            KI2701Stream.Write(KIByte, 0, KIData.Length);
            //  Send data

        public static void connect(string ip)
            object zz;
            object z;
                KI2701Client.Connect(ip, port);
                KI2701Stream = KI2701Client.GetStream();
                if ((KI2701Stream.CanWrite && KI2701Stream.CanRead))
                    connected = true;
                    connected = false;
            catch (Exception e)
                System.Net.Sockets.SocketException errnum = new System.Net.Sockets.SocketException();
                // .ErrorCode()
                string aa;
                switch (errnum.ErrorCode)
                    case 10060:
                        MessageBox.Show("Could not connect to the 2701, please recheck your connections and network settings and try again ", "Time Out Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
                    case 10061:
                        MessageBox.Show("Could not open connection because instrument has an open connection to another application.  Close th" +
                             "e connected application or power cycle the instrument to close existing connection", "Connection Refused !", MessageBoxButtons.OK, MessageBoxIcon.Error);
                        MessageBox.Show(("Error has occured:  "
                              + (errnum.ErrorCode + ("  " + e.Message))), "Error has been detected !", MessageBoxButtons.OK, MessageBoxIcon.Error);

        public static void disconnect()
            if ((connected == true))
                connected = false;
                KI2701Client = null;
                dis = true;
            connected = false;

        public static void KI2701send(string data)
            // Send data
            byte senddata;

        public static void KIInput(ref string KIstatus)
            KI2701Read(ref KIData);
            if ((KIData == "1"))
                KIstatus = "Front";
                KIstatus = "Rear";

        public static void KI2701Read(ref string KIdata)
            //  Read network stream into byte buffer
            byte[] bytes = new byte[KI2701Client.ReceiveBufferSize];
            KI2701Stream.Read(bytes, 0, KI2701Client.ReceiveBufferSize);
            KIdata = System.Text.ASCIIEncoding.ASCII.GetString(bytes);
            //  Debug.WriteLine(KIdata)

        public ArrayList arChamberInfo = new ArrayList();
        public ArrayList arTimers = new ArrayList();

        private global::Keithley2701ClassLib.Class1 K2701 = new Class1();

        If I try to access anything under K2701, I get the standard options, not the exposed methods,  What's wrong?  Thanks!

Are you sure you listed it in your postage correctly? There is no Class1 defined in the Keithley2701 namespace :( only General. Another point - you have everything static, you don't need to create an instance of the class in this case, just use class-scope, not instance-scope, e.g:

Keithley2701ClassLib.send( "..." );

and lastly, if you added this project to your project, why do you use global? just doing this:

using Keithley2701ClassLib;


should give you access to the namespace and enable intellisense for the class.

And remove the assembly reference if you have put the project into the main solution.  I don't know which one has precedence, but the assembly reference is not per configuration, so you can only reference the debug or release assembly and it will be for both configurations of the dependent project.
