    2. Microsoft.SharePoint

    3. System.Web

  7. Replace the autogenerated code in Program.cs with the code listed at the end of this procedure.

            {
                using (new Microsoft.SharePoint.SPServiceContextScope(SPServiceContext.GetContext(site)))

                    if (SPFarm.Joined == false) throw new Exception("You are not running in a server in a SharePoint Farm");

                    }

                    // Let the user choose the model by ID.
                    Console.WriteLine("Type the ID of the Model to export");

                    foreach (Model m in models)
                    {
                        //Make sure the model is there by ID
                        if (m.Id == modelToExport)
                        {
                            Console.WriteLine("Writing model to:");
                            Console.WriteLine(m.Name + ".xml");
                            //Export the model with all contents to model name file with XML extension.
                            System.IO.File.WriteAllText(m.Name + ".xml", m.WriteXml(Microsoft.SharePoint.BusinessData.Parser.PackageContents.All), System.Text.Encoding.Unicode);                        }
                    }
                }
