WinForm server-side object model error

Hi All,

I am trying to create a WinForm that interacts with the SP server-side object model but my site URL is not being recognized.  All this is being done on my SharePoint 2010 VM.

Error below:

System.IO.FileNotFoundException was unhandled
  Message=The Web application at http://win-2n0d15326id/iad could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

Here's what my form looks like:
Product Form
Here's the code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using Microsoft.SharePoint;

namespace WPFSPTestApp
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        string strSPSiteURL = "";
        string strSPListName = "";
        string strProductName = "";
        string strProductSKU = "";
        string strProductPrice = "";

        public MainWindow()
        {
            InitializeComponent();
        }

        private void btnLoad_Click(object sender, RoutedEventArgs e)
        {
            strSPSiteURL = txtbxSPURL.Text;
            strSPListName = txtbxListName.Text;
            strProductName = txtbxProductName.Text;
            strProductSKU = txtbxProductSKU.Text;
            strProductPrice = txtbxProductPrice.Text;

            using (SPSite site = new SPSite(strSPSiteURL))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    web.AllowUnsafeUpdates = true;

                    SPList list = web.Lists[strSPListName];
                    SPListItem Item = list.Items.Add();
                    Item["Title"] = strProductName;
                    Item["Product_SKU"] = strProductSKU;
                    Item["Price"] = strProductPrice;
                    Item.Update();

                    web.AllowUnsafeUpdates = false;
                }
            }
        }

        private void btnExit_Click(object sender, RoutedEventArgs e)
        {
            Application.Current.Shutdown();
        }

        private void btnClear_Click(object sender, RoutedEventArgs e)
        {
            txtbxListName.Text = "";
            txtbxSPURL.Text = "";
            txtbxProductName.Text = "";
            txtbxProductSKU.Text = "";
            txtbxProductPrice.Text = "";
        }
    }
}

Hi,
can you please verify, that in the build options of your winforms project you have selected x64 build target?
When you build x86/32 bit application you normally get exactly the same error message.
