.net XML序列化程序引发异常：“0”；“未找到方法”；

正在引发以下异常：

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

奇怪的是：它在团队中除我之外的所有其他开发工作站上都可以正常工作。这是许多失败测试中的一个，所有测试都以相同的错误失败。救命啊

System.MissingMethodException几乎总是.NET应用程序环境不正确的症状（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。当旧程序集停留在不应该停留的地方时，可能会发生此异常。重新部署后重新启动IIS
• 使用

  gacutil/u DLL\u NAME

  从GAC中删除任何依赖程序集。在此之后重新启动IIS。使用

  gacutil/if”“
