var txnSerializer = new TxnSerializer(); //generated serializer
TextWriter writer = new StringWriter();
txnSerializer.Serialize(writer, response.ReturnValue);

这里有一个奇怪的部分：除了我的以外，它在团队中的所有其他开发工作站上都能正常工作。这是许多失败测试中的一个，所有失败都有相同的错误。救命啊！

System.MissingMethodException几乎总是不正确的.NET应用程序环境的症状（例如，DLL版本不匹配）。我会尝试以下行动：

重建并重新部署整个解决方案。根据您的部署选项，您可能希望在重新部署之前删除（清除）部署文件夹中的所有现有.DLL。当旧程序集在它们不应存在的位置挥之时，就会发生此异常。重新部署后重新启动IIS。
使用gacutil /u DLL_NAME从GAC中删除所有相关程序集。在此之后重新启动IIS。使用gacutil /if "<path to the assembly .dll file>"

XML Serializer抛出异常：＆＃34;找不到方法＆＃34;
