.NET代码生成|无法在Visual Studio 2008中创建T4模板

Question

我在我的机器上安装了Visual Studio 2008（许可的）。 当我尝试向项目添加新的.tt（比如bar.tt）文件时，会生成以下代码：

我在截屏视频中看到，应该打开一个空的.tt文件，开发人员输入T4代码。即使我删除了代码并输入T4代码，也会出现构建错误。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Linq;
using System.Reflection;
using System.Windows.Forms;

namespace Foobar
{
    partial class bar : Form
    {
        public bar()
        {
            InitializeComponent();
            this.Text = String.Format("About {0} {0}", AssemblyTitle);
            this.labelProductName.Text = AssemblyProduct;
            this.labelVersion.Text = String.Format("Version {0} {0}", AssemblyVersion);
            this.labelCopyright.Text = AssemblyCopyright;
            this.labelCompanyName.Text = AssemblyCompany;
            this.textBoxDescription.Text = AssemblyDescription;
        }

        #region Assembly Attribute Accessors

        public string AssemblyTitle
        {
            get
            {
                object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyTitleAttribute), false);
                if(attributes.Length > 0)
                {

                    {
                        return titleAttribute.Title;
                    }
                }
                return System.IO.Path.GetFileNameWithoutExtension(Assembly.GetExecutingAssembly().CodeBase);

        public string AssemblyVersion
        {

            {
                return Assembly.GetExecutingAssembly().GetName().Version.ToString();
            }
        }

                if (attributes.Length == 0)
                {
                    return "";

                if (attributes.Length == 0)
                {
                    return "";
                }
                return ((AssemblyCopyrightAttribute)attributes[0]).Copyright;
            }
        }

        public string AssemblyCompany
        {
            get
            {
                object[] attributes = Assembly.GetExecutingAssembly().GetCustomAttributes(typeof(AssemblyCompanyAttribute), false);
                if (attributes.Length == 0)
                {
                    return "";
                }
                return ((AssemblyCompanyAttribute)attributes[0]).Company;
            }
        }
        #endregion
    }
}

编辑：我没有单独下载任何T4软件，因为我知道它已经随Visual Studio 2008一起提供。
