T4 An Exception was thrown while processing the template.

Question

使用T4模板来进行代码生成，因为要做成个代码代码生成的扩展，所以参照MSDN的示例： http://msdn.microsoft.com/zh-cn/library/bb126579 写了个自定义的处理引擎，本地运行没有问题，但是部署到服务器之后出现了如下的异常错误：

An Exception was thrown while processing the template.  The following Exception was thrown:
System.Runtime.Serialization.SerializationException: Type is not resolved for member 'Microsoft.VisualStudio.TextTemplating.AssemblyResolver,Microsoft.VisualStudio.TextTemplating.10.0, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
   at System.AppDomain.add_AssemblyResolve(ResolveEventHandler value)
   at Microsoft.VisualStudio.TextTemplating.Engine.CompileAndRunCode(String generatorCode, ITextTemplatingEngineHost host, TemplateProcessingSession session)
   at Microsoft.VisualStudio.TextTemplating.Engine.ProcessTemplateImplementation(TemplateProcessingSession session, String content, ITextTemplatingEngineHost host, String className, String classNamespace)

这个是调用自定义处理引擎的方法

public string GenerateCodeByT4(string databaseName, string objectName, string objectType,string baseClass)
        {
            CustomTextTemplatingEngineHost host = new CustomTextTemplatingEngineHost();
            if (objectType.First2Upper() == "Table")
            {
                var talbe = DataBaseHelper.GetTableByName(databaseName, objectName);
                host.Session = new TextTemplatingSession();
                host.Session.Add("Table", talbe);
            }
            else
            {
                var view = DataBaseHelper.GetViewByName(databaseName, objectName);
                host.Session = new TextTemplatingSession();
                host.Session.Add("View", view);
            }
            host.Session.Add("BaseClass", baseClass);
            host.Session.Add("ItemType", objectType.First2Upper());
            host.TemplateFileValue = Path.Combine(Request.PhysicalApplicationPath, "bin", "test.tt");

            string path = Path.Combine(Request.PhysicalApplicationPath,"Content","EntityClass.txt");
            if (System.IO.File.Exists(path))
            {
                using (StreamReader sr = new StreamReader(path))
                {
                    string input = sr.ReadToEnd();
                    Engine engine = new Engine();
                    string output = engine.ProcessTemplate(input, host);
                    foreach (CompilerError error in host.Errors)
                    {
                        output += error.ErrorText + "\r\n";
                    }
                    StringBuilder stb = new System.Text.StringBuilder();
                    stb.Append("<pre class=\"brush: c#; class-name:'CodeGenerate'\" >");
                    stb.Append(output);
                    stb.Append("</pre>");
                    return stb.ToString();
                }
            }
            return "T4 template doesn't exists";
        }
请各位大大帮忙看看问题，急了一天了都
